I bought some headers at a swap meet that are supposedly off of an older chevy pickup small block. They are in great shape and was going to try throw them on my sons 75 chevy tomorow as his exhaust fell off this weekend. Now I can pull the air pump too.

My question is: The only number stamped on these headers are "7301". Can anyone identify them?
Thanks
Tom

All I could find was a 3797901 or 7901 using the last four #s. They were ram's horns used on '63 Corvettes. Are they 2" or 2 1/2" exhaust?

His exhaust fell off this weekend

Oh no, better get velcro! I hope you mean like the muffler or pipes. If the manifolds fell off, new set of headers may just be the tip of the iceburg.
