LT1 exhaust manifolds...

[Barbecue]

Hey team,

Quick question if you don't mind sharing your expertise. In my area a fellow has for sale a pair of LT1 Trans Am exhaust manifolds, not sure of year (picture attached). Apparently they were factory on some Camaros, Impala SS and Trans Am cars. The exhaust outlets look to be in perfect position to replace my stock exhaust manifolds ('86 Silverado), but what I'm not sure of is whether or not they would bolt up to my stock cylinder heads. Thoughts?

Thanks so much in advance,

BBQ

Disregard. I've figured out that apparently these will not fit due to differing bolt pattern. Cheers, guys.

I have a set of LT1 manifolds off a 96 Caprice I had on the 350 in my 81 C20. They bolt on , the rear holes don't line up and you have to drill holes in the manifold for the front holes.
