I wanted to know what you were runing you your engine, who makes it, and what size shot?
What do you run on a 305?
What do you run on a 350?
I have a carbed Z with the stock intake manifold and edelbrook 750 vaccume secondary.
I'm not sure what the engine is, but it is fairly new.
The guy that sold it to me said he had a rebuilt 350 put in, its a new engine fresh paint all over with a new thin film of leaked oil on one side.
I had a mirror on a stick and a light, I could part of the block casting # (GM140- couldn't see any more) I need to move some wires and I'll be able see all of them.
I will get a head # soon too.
It has an older engine with out the 5.7 or 5.0 on the driver side.

 

check this out you'll see what i run in my 305!!
