- In this video Rob picks up a small block Chevy Vortec 350 and tears it down to see if the engine can be saved and be useable. He pulls out the crank, pistons, connecting rods, main caps hydraulic roller cam shaft, timing chain to get it ready to go to the machine shop.
$300 near me , you get a cleaned block with bore over cylinders to what ever size you want , new freeze plugs and cam bearings
Where's that?

Rebuilding mine right now. Std. bore flat top pistons, aftermarket rods, ZZ4 cam, roller rockers, thin shim head gaskets, Mild porting, 1" intake spacer, hand made as you can't get the Taylor billet one any more, SS headers, opened up throttle body, and doing heads right now to get clearance for the cam.
That engine is supposed to have hydraulic roller tappet cam. I wouldnt change it. You dont have to worry about wiping cam lobes.
Understandable, like I said at the end of the video, plans have completely changed for what I was originally going to do with this engine. So it is not getting a flat tappet or even a hydraulic roller.
The cutlass is my favorite car. Cant wait to see more stuff from you
@@daniel202010 Thanks! Just a little hint hint… the Cutlass does need an engine… not sure where to find one though. 🤔🙄😆 (full sarcasm intended)
Yeah I'm looking for a 4 bolt main
Good information here, thank for sharing!
Awesome video bro! A lot of great information 👍
Glad that you enjoyed!
@@BoneyardRevivals yes sir! I’ve got a vortec 350 as well gettin ready to teardown
Thanks
Not all the l31s are drilled for a mechanical fuel pump, the housing in the block will be but they skip the drilling on most of them
Yea that’s why I was surprised to see that this one was drilled. It’s kinda cool because you could go with a retro hydraulic roller cam or if you where on an extreme budget go old school with a hydraulic flat tappet.
@@BoneyardRevivals yea, lucky find no doubt! Make sure if u go roller cam you get the right style. Retrofit roller cams are made for blocks that are non roller or basically anything not a vortec 😅 OE roller cam is what u will want for it, also called step nose cam but the oe step nose style using the cam retainer plate and a oe roller style timing/cam gear because the bolts sit closer together on the front of cam because that step nose for the plate also using the retainer plate theres no need for a cam button. The retrofit front of cam is flat like a flat tappet cam and can use the regular gear and bolt spacing but since it doesn't use the retainer plate u need the cam button to hold it in the block and keep from walking. Hopefully this made sense 😂 and if u already knew all that my bad haha maybe someone else can use the info. I didn't really get the difference on my first roller block until I had done some reading lol. The main thing u want to watch is matching your timing set and cam gear up with the right style or else you won't be able to bolt it on and have to deal with all that bs of replacing it.
Also u can use either style cam in the block either a retrofit roller or an oe style step nose roller. You just have to know about the cam retainer plate vs a cam button and the cam gear bolt spacing for timing set. Either style lifters u can go with. The stock style are cheaper then the link bar lifters and since you already have the dog bones that hold those id stay with oe style lifters and save a few hundred bucks not getting link bars.
I don’t want to spoil to much info but I’ll just leave these few words here: (Full Solid roller) I’ll let you and anyone else who reads these comments to paint the picture for the future plans on this engine. Thank you for sharing all that awesome info!
@@BoneyardRevivals Hell yea! Go big or go home, I like it..Definitely staying up to date on it 😁
All vortex 350 engine had a main problem. The rear main is about one thousand too small . If you don't turn the crank get with a local engine builder her can get the proper main bearing kit . This is not my opinion. It's a fact. Good luck.
No worries, she’s at the machine shop right now. We got a pretty snazzy build in mind for it. Thanks for the info!
Bro I've swapped the exact same engine into a 95 GMC Safari, I bought it, machined the crank, threw all new bearings and rings in it, flat top pistons, hei distributor, 4bbl carb and intake, re used the factory roller lifters with a small roller cam, I drive it all the time and I've been beating the hell out of it for 11 years now, it starts instantly even in the dead of winter.
Heres mine, this was about three years ago. ua-cam.com/video/Epd-8FjNaXM/v-deo.html
@@quietcool4884 I had plans for something similar to your build when I first got the engine but now my plans have changed.
@@BoneyardRevivals Cool, I'll watch and see what you do. I just added a GT45 turbo to mine last fall but haven't made a vid yet.
You bring a little comic relief in your vid.
I'm looking for a 350 Chevy motor for my 87 Chevy caprice classic
The Caprices are cool! Look around in some local junkyards you might be able to find one.
I want to buy a Vortec to get the roller cam .
They are definitely one of the best cam set ups to run now days especially considering you don’t have to do any break in procedure like you do with a hydraulic flat tappet. But the prices to get a good quality set hydraulic roller lifters ain’t cheap either. But over all the hydraulic roller set ups are super nice and easy.
Why the hell would you put a flat tapper cam in it?
It would keep the build way more affordable but no worries, that is not what is going in it. We changed some plans.
You can reuse factory roller lifters. I’ve
Done it. Just changed the cam and springs
It’s never a good idea to reuse lifters in my opinion. I am sure you can get away with it since it’s a hydraulic roller but you can not do that with a hydraulic flat tappet, but like I said we are taking this engine in a completely different direction.
@@BoneyardRevivals you Definitely can’t do it with a flat tappet. You can wilth a roller though.
@@canabox7112 it’s definitely not a good idea but don’t think it can’t be done I’ve reused flattappet lifters aswell. I’ve done it a few times with great luck. Old hotrodders have done about anything you can think of. But yes hydraulic rollers are 100% ok to reuse if the rollers are in good condition
amazing how most V8s on UA-cam are 4 bolt main..
We have a 2 bolt main build video too
@@BoneyardRevivals Honestly that's a lot of horsepower for a 4-bolt main to be required, I just wanted to be lucky enough to find one lol
How much did you get charged to remachine the block
The block is still at the shop getting built into a 383
@@BoneyardRevivals so its gonna be like 5500?
@@jeffklonowski6816 I wish 🤣🤣🤣. I forgot to mention the part where it will be a 600 horse solid roller cam 383. So probably double your original guess. 🤣
plans always do a 180.....lol...
Originally it was going to be a slightly better then stock rebuild with a carb swap, but now… well let’s just say those horse powers are going to be up while the bank account will be down. 😂
@@BoneyardRevivals can't have fun with money that sits in the bank....lol
What year is the vortex
96 97 98 trucks and vans. Some vans in 99
They were actually put in some vans into the early 2000s. I think 02 or 03. Not sure what year this block is and it’s currently at the machine shop so I cant run the casting numbers. I do know it came out of a K-2500 or K-3500 pick up.
Got a chance to look at the casting number on my block. It is 10243880 which would date this block from 1995 to 2000. And as I mentioned before, it is a 4 bolt main out of a heavy duty truck.
Where are you located and can you replace mine same engine
I can spell vortec . I hate auto correct.
