1972 chevy LS-1 swap
 

I am currently doing a frame off 1972 chevy 4x4 blazer and installing a LS-1 engine and need to find out if anyone has done this and can you help with the exhaust manifolds?

Re: 1972 chevy LS-1 swap
 

Corvette manifolds I believe stay tighter to the engine. I've always just made headers to work

Re: 1972 chevy LS-1 swap
 

do you make and sell?

Re: 1972 chevy LS-1 swap
 

I think the tbss manifolds work. And I gonna watch your progress I'm going to be doing the same thing. What did you use for the cross member?

Re: 1972 chevy LS-1 swap
 

For Trans used the stock one and for the motor used the Pacific fab cross member!

what year?

Re: 1972 chevy LS-1 swap
 

I have pacesetter long tube headers for a TBSS and they hit my shackles so I have to have them modified. I think Doug Thorley makes a conversion header.

Re: 1972 chevy LS-1 swap
 

There's some 4x4 swap guys out there. I was going to use the TBSS manifolds on mine but put headers on instead. I'll sell them if you need them. You also need a special engine cross member unless you plan on fabbing one yourself. I got mine from Pacific Fabrication.

that is where I got mine from!

Re: 1972 chevy LS-1 swap
 

GMC you have some headers for sale? For this application?

Re: 1972 chevy LS-1 swap
 

I have the TBSS factory manifolds. I ended up buying Doug Thorley headears. They were like 6 or 7 hundred bucks, I forget.

I do, but I need the truck, each set I build are one off to fit a particular request or requirement

2010 + Camaro manifolds tuck tight to the block and are 2.5" at the collector.

Check out this thread and the LSx section in general....

GMC. Which Tri-Y'S did you buy?

Re: 1972 chevy LS-1 swap
 

I used 2012 Camaro manifolds. They fit like a glove.

TBSS work good

Re: 1972 chevy LS-1 swap
 

I used TBSS manifolds, cut the flanges off, and welded some pipe to them to extend down under the truck, to V-bands
