588" motor in 68 cuda

Update the heads are done. They tried something a little different. They kept the port a little smaller, to help with it being a street car Wink. Still very good flow for that CC port. When he really opens them up, he said he gets about 415-420 cfm. I am also having him port the hell out of a mopar 337 manifold. I will be dynoing both the 337 and a 440-3x. Larry Smith is the head porter. He does a lot of nascar stuff.

This is a note from my engine builder:
Cool with me. Progress being made. Heads done and assembled. Larry tried something a little different on your head porting. We got them up to 405 on the intakes. Oh yeah the different part, they are only about 335cc runners. That is 50cc smaller than the Indy CNC 385 and virtually the same flow……….it being a street motor and all…….LOL!
