building a 70 chev stepside... customed - The 1947 - Present Chevrolet & GMC Truck Message Board Network

daesch · 05-09-2005, 10:52 PM

Anybody know if i am going to have to change my perches or shock mounts?
I have 82 or so 3/4 ton axels.. dana 44 and 14 bolt semi float axels that I am going to stuff underneath my 70 chevy sb stepside...

when I am finished it will be..

350 crate motor ( newer single rear main seal, valve covers bolt thru center)
I think i need motor mount conversion here??!?
Also not sure about transmition.. i have a sm456 with np205 but am not sure if this newer motor has a spot for putting clutch linkage?

its is going to get 6 inch of lift by bds.
35 inch tyres

pontiac gto seats..

I need headers that wont interfere with clutch linkage... anybody have any good suggestions?

just got the frame back from sand blaster.. good shape..

I have most the parts i need, except a whole lot of minor parts (about 1000 $ worth of odds and ends)

and at least a year of hard work.. ( the shame is it will never go off road.. thats what the 86 chevy and grizzly is 4)

project big toy has begun....
any advice anybody can give would be much appreciated!

short or long?

I am swapping out my rears for a 10 bolt and 14 bolt out of a '78. The front perches and shock brkts are fine, but the rear perches on the 14 bolt are further apart than the eaton was. I am having to move them in closer to work. Hope this helps......

Me and my buddy both run hooker headers on our trucks, his is a 77 Fleetside and mine is a 77 stepside. We also both run the SM465 tranny, and his has a brand new crate motor in it, so I dont see why you would have any problems with clutch linkages or anything like that. Sounds like you have a fun project there, I am working on the replacement engine for my truck, then after I get that done, the body is going to come off, needs cab corners and rocker panels, and has a small dent in the front fender and rear bedside from plowing snow. I really like my stepside, especially when it looks nice and clean, Good luck with your project. Don't worry mine has never been in the mud either, I just don't want to clean all that crap out of all the fenders, that was probably why it lasted 10 years without a day in the garage till the cab corners started rusting since we last restored the truck. My buddy with his 77 likes to take his in the mud all the time, and that is probably why he truck coudl already use cab corners after only 10 months. I will try and post of pick of my truck when I can get one.

i have a 72 with 350 and hedman hedders. the clutch linkage was in the way so the rod had to be extended and the linkage shortened to accomodate for last tube on hedder

daesch · 05-11-2005, 06:18 PM

Thanks for the info... just need to dispell some worries i have been having.

Does anybody know how many hp I need to spin all 4 on dry pavement?

I was looking at rear disc brakes but 3 hunderd + dollars just for the brackets is nuts..

bigchevrolet · 05-11-2005, 07:51 PM

lots with auto not as much with standard but lots

**special-K** · 05-12-2005, 07:05 AM

You`ll need(guessing)500+hp and a whole lot of drivetrain beefing.

Where were you looking? You can find the brackets for $65-100, then you still need calipers/rotors/hoses. It adds up. Blackbirds has the kits that include everything.

daesch · 05-12-2005, 11:45 AM

Sorry it was brakets and rotors... still. The company was http://www.tsmmfg.com..
What is the web address for blackbird?
tsmmfg uses cadi rear calipers for brakes with e-brake... i can find those in a bone yard from 30-50 bucks... where as the want 300 a pair... just trying to save some cash.

**JIMs70GMC** · 05-15-2005, 06:43 PM

look in drink2manys signature. Also: diy4x.com, shakerbuilt.com, skyindustries.com all sell brackets, you supply everything else.
