I am not 100% sure but I believe you have to use a retro-fit cam made for this conversion. They have a smaller base circle as not to expose the oil hole or push the lifters out of the lifter bore.
@@1194video definitely was! I’ll be rebuilding a 302 soon and was hoping this conversion was possible. Now not only do I know it’s possible, I know I can do it
That is a really cool video and I had no idea such a kit existed. but today you can get retrofit roller lifters for 99 dollars on ebay. I don't know when they started making a kit like this, but 20 years ago this would of been awesome. It still is awesome because you never know with cheap ebay stuff. I would kind of question whether or not the 99 dollar retrofit lifters were good. Anyway thanks for sharing I just learnt something.
Damn ! I went to a Howards billet solid roller about three years ago and went with the link-bars cause i didn't know about any such kit; and though I went with premium bushing solid rollers, I'd actually had a link-bar come loose on the Hydraulic roller I had prior which was why I had to change the cam out in the first place. I acutally think, (as much as they had to be compressed) that the recommended high-rev springs I installed help keep mine oriented, (though they jack the overall coolent temp a good 20 degrees) yet I think going with the kit instead of the link-bars is a better set-up just for the lesser reciprocating weight if nothing else. After having one come loose on me, I'm no longer a fan of link bars.
Great video! Any reason why this is better than using the rollers with link bars on them instead, or are they both as good as the other just different?
I read somewhere that this setup is fine as long as the cam is under .500 lift. The Trick Flow TFS-1 is a little over that on the exhaust side but seems to work fine. Any more lift than that, and the oil groove in the lifter will be exposed causing a loss in oil pressure.
@@bartsarton2212 it’s no different than any engine. Lift if how tall the lobes are on the cam that make the valves open which are operated by the lifters forcing the pushrods up operating the rockers/vale’s lift. The lifters have a groove in the middle that oil flows to from the bore in the holes in the block. He is saying that if you have a very large cam that the lifter will go too far out of the bore hole and can’t oil properly….. but unless your engine is not stock it can only handle a certain amount of lift anyways or else the piston and valve will contact causing catastrophic failure
@@1194video Sorry, I wasn't clear. I meant what does your comment, "I’m running 60 cruising" mean in relation to Random Guy's comment about valve lift?
Great video! You showed me "how to" do the roller rockers, but do I need to do anything to the distributor? Gear etc...but like I say you did a great job on the lifter how to! Two thumbs up. Thanks you very much. Cheers B
Like the video. Thanks. Girlfriend has 76 f100 that we wanted to convert to roller cam. My question is can we the original heads with the roller cam? We're trying to keep original as possible. Thanks
that lifter valley is already susceptible to cracking right down the middle of the block at power rating 500 bhp. more holes in the valley just weakens it more. i wouldn't build much more than 400 bhp on that block. dart blocks have cured this problem .
Any issues with the lifter oil band coming out of the bore? My non roller Mopar LA 360/408 has short lifter bosses and for a hydraulic roller the only roller lifter I can use are the Morel/Huges retro rollers. There in its self is a problem with the hydraulic roller being taller and the already extreme pushrod angle causes excessive wear on the lifter bore its self and the plunger inside the lifter. The morels are egging my lifter bores from the extreme side load from the poor pushrod angle and they are failing with excessive leak down while running. If I was to do it again it would be with a factory LA roller block or sleeve the lifters with a taller sleeve to accommodate/support the taller lifter better and eliminate the lifter oil band from coming exposed at high lift.
The upper lifter is taller only to accommodate the keepers that hold them in position, the lifters themselves don’t come out of the bore past the sleeve, that would be catastrophic. I could not use standard lifters or they would not line up properly with the oil valley and would t have oil pressure to oil tue rockers, the lifters I have are specifically for the conversion of flat to roller.
Those don’t require the tray since they keep each other in position from turning. The tray just holds down the keepers holing the lifter rollers straight with the cam lobes
Very good info!! I did not know about this. Thanks for sharing with us. Is it a good idea to locktite the 1/4-20's? Red or Blue? Thanks again. Cheers from Motown/Dearborn.
Personally I'd use blue locktite on 1/4" and smaller. If you do use red, only a tiny amount. I've sheared a 3/8" bolt because some yahoo used to much red.
Would like to use this in my 70 ford 302. What lifters and cam is best for this conversion? I now the oiling whole for non roller blocks are lower . Which one did you use?
Overnight to allow them to pump up before installing them. I didn’t mention because it was a video mostly about the swap to roller installing the hold down
My question is I noticed the dog bones was coming up with the lifters. I watched this because I just did this and the retro lifters raise the retainers even higher that the oem roller lifters. Have you run this engine like this?
It was not the lifters that raised the dog bi es, the side of the block was not allowing it to sit flush, you can grind it out on each bore so that it doesn’t contact the side of the valley but I left it alone. You can watch it running in my video of the red 1967 mustang
Did the engine end up working well? What lifters did you choose?? Can this be done on an SBC 350??? WHAT LIFTERS DO I USE FOR AN SBC 350???? WHAT CAM DO I USE????? Sorry lol just got questions
Yes it’s been a year since and engine is still strong, you can buy the attached roller kit for your engine which has a bridge that runs from one to another lifter and as for cam you can go any size that does not require aftermarket pistons or heads, if you decide not to go roller the cam i recomend would be comp cams no. 12-231-2. it's 206 and 214 at .050 with .432 and .453 lift. if your going for low price, summit cam k1103 would work with 214 and 224 at .050 and .442 and .465 lift. you'd notice considerably less torque and drivability with this cam than the other but it would work ok but those are for flat not roller. So if you do go roller there are kits available for those as well
So i re-used the spider tray in my 383. How much pressure should be on the dog bones? Just enough to keep them down. I have this fear that the ear of the tray will somehow bend and release the dog bone making the lifter spin.
@@1194videono I meant the part that lays over the dog bones. My actual tray is torqued with loctite. I’m curious what actual pressure needs to be applied to the dog bones. This is just my OCD talking
I got a question I got a 1992 f150 351 non roller block, comp cam kit 35-512-8. Cam, roller lifters, timing, etc. I tapped my holes, got all the lifters installed, with the sypder, and wishbones. But whenever the lifter is pumped all the way up it’s coming in contact with the wishbone pushing it up about a 8th of a inch, is that normal? Or do I need the retro lifters? I think I’m fine, I just don’t want a noise valve train cause of it.
So do I need to worry about the lifter, traveling, too high at high RPMs and the oil hole on the lifter, raising to high and shooting out causing me to lose oil pressure being the non roller block lifter bore isn’t the same as oem roller block?
@@dustin2816 I measured where mine oils and the lifter and mi e was perfectly aligned with the oil journal, I’m holding 3/4 of a gauge on my oil pressure and it rises at higher rpm. Mi e is the kit designed for the conversion though, measure in the lifter hole down to the cam on neutral and lift to the oiler hole and measure your lifter to make sure it travels within the oiling area. You definitely gotta have it piling correctly or you will have a boat anchor
I like your work, very useful, and I do have a question, will you recommend retrofit camshaft in a stock 302 and do I have to change lifters as well? I appreciate your input
From what I've researched they are the same as well guy on another video on here said the part number for the Comp Cam kit and I looked it up and it's coming up the same as a regular stock roller lifter
As for cam specs, you will have to check to make sure your block is the same just non roller, then you can add roller lifters and kit to add cam. This cam roller kit is from jeggs if you want to check them out
@@boostedperformance4529 lol no worries, ppl will still drill through not paying attention. I personally would rather just buy a roller block. I think I’m going to stick this one from the mustang in my 65 f100 and build a 351 for the 67

You don’t see people taking out roller cam shafts to do flat tappet, because flat tappet is prone to wear where roller the lifter has a roller that rides on the cam rather than the friction from a flat tappet
@@antoinehaynes8479 no not at all, a lot of old school guys live the flat tappet, you can make good power for sure and great sounding cams but they were bad about wearing if the proper measures were not taken when breaking in the engine, I like both roller and flat but I’m saying I would not choose a flat tappet over a roller lifter
I did. It was a flat tappet and I changed it to a trick flow track max roller, that’s why you see in the video, roller lifters and drilling the block for the hold down for the wish bones that keep the lifters straight, I didn’t show installing the cam because if your doing a roller cam swap there is nothing extra needed to just pull out one cam and put another in its place.
that's not good, worse if you don't use stock style lifters and don't use a small base circle camshaft. When the camshaft lobe is at its maximum, lift the hole through which the lifter fills, it is exposed to the outside of the hole in the chamfer of the block, the other problem is that the lifter guides are not well seated on the surface of the block It should be flat, as in the roller blocks, and when it is in max lift there you can see that the lifters are lifting the guides when the guides should be resting fixed on the block, that at high rpm will very likely cause them to come out the guides and the lifters turn, causing damage to the lifter shaft and filling the engine with burrs. Mexican non-roller blocks don't have that chamfer, they lend themselves better to that modification.

Roller camshafts have a high failure rate. You do not gain enough from a roller camshaft to justify the conversion. All you get from a roller camshaft is a high maintenance engine.
I am not 100% sure but I believe you have to use a retro-fit cam made for this conversion. They have a smaller base circle as not to expose the oil hole or push the lifters out of the lifter bore.
You are correct, this is a small base circle cam

It is called a MELONIZED GEAR the two for ford engines IS A JOKE both gears have one hole to mount it NOT A THREW HOLE !!I was told to drill it out WHAT ! OK summit down the street went threw 2 DIST. no go on the gears at ( $125 ) EA. All ready destroyed one trying drill it to fit !!!~ carbide drill wont work need a lath to bore it out !!! and one thing 351W IS NOT THE SAME AS A 302W !!!!! SUMMIT LOOK UP FOR 302W I STOPPED THAT !!!
@@stephensalamone-v9x you don’t have to long as you change the distributor to a modern HEI
@@1194video I have a HEI and the shaft is .511 and the hardened gears are .401 and .531 Chevy and .491 I have gone threw 5 dist. 2 mallery and ford ! use the rong gear and it will eat it till it stops 36 deg worn off .so use the steel gear on your HEI and see what happens I DID !!
@@stephensalamone-v9x dang, that would be terrible, and the shavings to boot. I haven’t have any problems out of mine thank God, you think they would I firm of which gear to use, I have a cast iron gear on my distributor. Idk how long it will last but I hope I never have issues with it.
@@1194video I think that the ford mock ! was in for 5 years and they raced it ! it was a wreck I put it back and running
Roller camshafts have a high failure rate. You do not gain enough from a roller camshaft to justify the conversion. All you get from a roller camshaft is a high maintenance engine.
Every engine pretty much past 90 is roller
You're kind dumb ain't ya. 🤦♂
Too much money!
Know what it cost? 100.00 for the kit.
LOL !!!
You, lol
Do you have to used a reduced base cam after conversion?
