That’s the way I have mine. 84.5. Have left my smog pump just sitting there on mine, for now. Been 4 years lol. LMR has all these diagrams with belt sizes on their website which is what I used at the time.
I use to get rid of the smog and ac and move the ps up. Now I'm 44, I NEED ac 🤣🤣🤣
You and me both, gotta have my ac!
To be honest I always went the shorter belt version. I worried about how close the belt was to itself and kept checking. I'd rather get a new belt every 2 or 3 years and have the cleaner look. Just my opinion. The front of the motor just looks cleaner that way imo
To each their own buddy!
Foxbodylife since early 90s to present time I’ve done this more then 2dozen times over the years and it’s worked just fine Dude what are you doing listen on the 1st graph your showing ps on the drivers side and your correct way the 2nd graph is showing ac and ps on the driver side. Show me how to do it with the 1st graph witch that’s what is on my engine explain it the right way with the same graphs please foxbodylife
I liked to have never figured out how to run the belt on my 351 Windsor, no smog pump or A/C. I ended up running it exactly like you said, was the correct way.
Took me 4 different trips to the part store to finally get the correct belt for my 351
@@graigorygilbert602 yes sir, I bought 4 different belts before I got the right one ☝️
Yeah that requires some sting method to get the correct length
@@floydmarseeii4007 did you go carb or efi? I went efi and ending up with a huge part list to keep it as stock looking as possible
@@graigorygilbert602 I went with a Elderbrock performer rpm intake, 1” aluminum spacer, and a 8156 Barry Grant prepared 750 Holley carb, HO roller cam.
I need a route with only the alternator and water pump. Going to a manual rack. I've heard I need to take apart and reverse the tensioner.
i just did this today same routing on my 87 with old BBK underdrive pulleys on the crank and water pump and i've done the 3g alternator upgrade.
tried so many different belts local parts stores had on hand.. second to last try was a gates 77" and with the tensioner pulled all the way up couldnt get the belt on the alt.. so went to a 77-1/2" which was within the tensioners 'range' gauge but there was maybe a credit card's clearance between the water pump and tensioner pulley.. had to pull the alternator's original top mount bolt for a slimmer grade 8 bolt and bump the top of the alt toward the pass side about 1/4 of an inch and secured it in place a window net mounting tab for a tube chassis car between the bolt and the spot the tensioner bolts onto.. can fit the tip of my pointer finger between the pulleys now but it's gunna chew it self if it stretches.. what a day..
thinking it's time to lop off the spring tensioner side of the original alternator bracket and grab some metal dowels for spacing, a threaded sleeve, and a couple heim joints from the local tractor supply for manual adjustment. 🙃
What about alt, water pump and crank? Best route for the belt?
My truck has the smog pump delete. However, I have a larger pulleys on crank and water pump. Wound up using a 90” belt for the routing.
For the smog pump delete everyone said to go with a 84.5" belt I tried it and ended up going with a 85" belt
I have a 351W with Vortech custom bracket and smog delete. Still have to measure for belt length.
Wish I would of seen this like 6months ago I have the short belt.
Sorry boss, I am late as always
Ok
So serious question here.
I just went through this a couple of weeks ago. I studied the routing pic circulating the interwebs.
I have the 3G upgrade with the LMR bracket. So I just used the shorter belt, (I think 78.5), and drilled a hole for the tensioner pin, (not the bolt), so I could rotate it slightly, for that exact reason. So it doesn’t rub when the belt stretches. I rotated it to a point where the range needle is still relevant also.
Any way. Getting to my point.
So the routing you show at the beginning will spin the WP counterclockwise, but the one you used is clockwise. Correct? I must have traces my finger around those pics 20 times to grasp it. Lol
Are you saying the WP will work correctly spinning either direction?
I mean, I’m fine for now, but I may have to change it someday.
Thanks a bunch.
Donnie
Easy knowing the belt size👍🏼👍🏼👍🏼
What about for a car with AC delete? My 88 Tbird has AX delete and I'm upgrading to high amp alternator, want to put on a new belt at the same time.
can you clock your tensioner up? mine has 2 positions.
What is cs? Mean can you move cs with your hand? Mines hard to turn by hand is that normal? The fan is also hard to turn when car is off, please let me know.
Great video! Thanks for taking the time to show the correct way it is done! 💯👊🏾
Putting a fox style system on my 65. How about no PS, A/C, or factory tensioner? I really don’t want to use idler pulleys if I don’t have to.
Good Informative Video!!
Thats the goal boss
Dover's truck. Is the front suspension custom or a bolt in kit. Let me know the details, please. I have a '79 and have been considering the Heidt's front end kit and eventually going with a Godzilla and a 6R80. the twin I beams need to go to give me better brakes and better wheel options, such as a 5 x 4 3/4". Thanks, for all of the how to's.
How much would you say you need to drop from 84.5 inches if you’re gonna do underdrive pulleys at the same time (alternator, crank and water pump). TIA 👍🏻
Thank you for sharing this with me and others too. Okay. Keep up the great work. Okay.
Belt routing 101 so many folks dont get this right. Here it is!
I stick with what works! lol
@@FoxcastMedia yes sir !!
u have any help with the EGR vacuum emissions lines I have a leak idle surge 50 rpm wants to almost stall at redight
What is the part number on the belt?
Water pump direction
Water pump is spinning the correct direction using this routing
It doesn't change the direction the pulley turns, but rather the order they're pulled. Originally, the water pump was pulled last; w/"Caleb's way", it's pulled first.
GATES BELTS ... they don't stretch nearly as much as cheap ones.
Thats great. Unless you're only running alternator and power steering. Then you have to do it first way? Lol
Man I routed mine the same way and it squals constantly! Belt is tight but not too tight. Nothing is locked up but man it squeals constantly. Any suggestions? I was told that I need the smog delete pulley instead of bypassing it and that will stop the squealing
Probably got another pulley going bad or belt too tight or wrong routing of belt
