66 suburban 5.3 swap
I'm building a 66 suburban trying to put the 5.3 out of an 04 Chevy truck into it. I have the motor mounts figured out and I'm gathering up other parts for the swap. My question is and I know it has probably been asked a hundred times will the truck exhaust manifolds fit without doing anything to the frame or do I need to try and find Camaro manifolds or headers? I will only be lowering truck about 2-3 inches so ground clearance isn't an issue.

Re: 66 suburban 5.3 swap
From what i have read you can not use the factory truck manifolds without cutting/heating bending the frame. 1998-200? 2010 up camaro or trail blazer manifolds fit most swaps. Hooker makes swap manifolds that fit

Re: 66 suburban 5.3 swap
A friend built a 66 Suburban with the 5.3 and he used the Trailblazer SS manifolds.

Re: 66 suburban 5.3 swap
Started the install of the 5.3 into the 66 looks like the ac compressor is going to be a tight fit in the lower position . Will it clear or is there another route to take looking for some ideas thanks

Re: 66 suburban 5.3 swap
best to use the high mount.
I used Docs Blocks and trimmed the frame rail a tad. I don't know if Docs Blocks are used any longer. actually here they are. http://www.acsource.com/hoseblockhor...oringtype.aspx

Re: 66 suburban 5.3 swap
Thanks for all the replies I found a set of 2010 Camaro exhaust manifolds with the cats still on them locally. Tried them on and only had a small amount of clearance problem on motor mount nothing big. Decided to try and keep the ac compressor on the bottom for now and had to make a small notch on the frame. Tomorrow night maybe I can make the trans mount and get it all bolted in.
