So i have an 1982 camaro with a 350 swap from a second gen z28. Recently I noticed an exhaust leak and realized there are screws on the back of the manifold and a couple of them came loose. First question is what the heck are those screws for?!? Second is there something I can do to plug the holes since the threads are messed up (welding it or something)? Third....I went to the local junkyard and looked for a replacement but didn't find anything close...so is there a stock replacement for the drivers side I can buy?

THANKS!

 

this is what i need a replacement for....its a stock exhaust manifold for a second gen camaro 350. if you have one PM me!!! if u know where to get a cheap one PM me! THANKS

 

that looks more like a third gen manifold to me.

try a dorman part #674-518. $85 at advance auto or im sure you could do a search and find it cheaper or closer to you.

Or dorman# 674-276 $109 at advance 2nd gen camaro w/ CA emissions

 

Those holes look like where A.I.R. tubes go. 1/4" NPT pipe plugs will plug them right up.

 

I am not familiar with A.I.R. and the plugs have basically broken off so cant plug them anymore... tried to JB weld but it melts at 600

 

Thanks! thats what i was looking for...now to find a cheap price lol

 

You could weld those holes shut, or tap new threads & get bigger plugs to fit those threads.

Cheaper than buying whole new parts.

 

was going to try but i guess welding cast is hard....have to stick weld....

 

Braze them closed if the threads are all f**ked up.
