exhaust manifold

Hi. I just aquired a set of manifolds off of a 99 Tahoe 5.7 will they bolt up to my 79 350 heads. thanks bill

 

Nope don't think so.

 

the short answer is yes, but the outlets don't hug the block as closely as the older models and may interfere with the chassis. there is an egr gas outlet on the left manifold that will need to be plugged as well

 

Thanks they are going into my 49 merc it sounds like the wider outlets will be just what I need. bill

 

Lots of circle try guys around here use them with their Crate series motors. Supposedly gives them a few extra hp.
