Its a 9/1 compression with stock iron heads , 323 rear gears and a 727 auto trans.
I bought a edelbrock rpm manifold for it replacing the stock one and possibly a holley 750 replacing the edelbrock 650 on it.

This is a street car that im looking at doing some mild upgrades to it and looking for advice on cam selection that's got a nice idling sound to it that will perform.

it was mentioned a Comp 268H , 270H , ex268 however I have no idea what that means. I looked up Comp Cam 270H and it came up as a Chevrolet cam...be easy on me Im learning lol
