Gee guys what happen to all the old truck builders out there. Seems like all you guys hop up new or fairly new trucks. I am doing a ground up building on a 1972 chevy p.u. swaping in a 5.3 vortec and overdrive trans.
Anyone care to show some input. Ordered the conversion mounts. But looking for a company that makes 5.3 headers for the 72. Also thinkin of changing the intake to a LS-1 if it will fit and help. Any ideas on a hi-output cam. Its a weekend driver,automatic with stall torque converter. Thanks !!!!

 

check out firstgen. i know there are a few more but i forget names.

don't waste your money on the ls1 intake. the truck mani is better for trucks do your self a favor and search on it first. search is your friend. complicated at times but friendly.

 

i am currently doing a 5.3 swap on my 81 c10. I would like to find a set of headers for that.

Street and performance makes a set of headers for the 72 style truck i am pretty sure.

 

I Have A Friend That Put An Ls1 In A S10 Blazer And He Did Some Research And He Ended Up Putting The Vette Manifolds They R Like Shorts And Were Cheap

 

I would like to help you out with headers but frankly dont know what will fit.I just started work for a custom header manufacturer.we do custom work for people who bring thier truck in but if you cant,We still have all the flanges and stuff.maybe you can get a set of Ls1 headers cheap and modify them.if you dont like the way they come out then we can copy them and make a nice set.good luck--Todd

 

street and performance "HAS" a set for the 68-72 trucks. You might give them a call
