Cool
Zimmy,

Plagued? I rather enjoy that sound. I have seen both the 427 and 428 heads from Edelbrock. I would be prepard for a small amount of porting to match your intake for best results. Not porting the heads pre se, but rather matching your intake to the ports which I imagine will take a little work..

I think your problem will not go away with changing the heads.. what you are probably experiencing is more likely a slight overlap in valve timing and ignition timing since you changed the cam.. The good news is you are making lots of power, the bad news is you are doing it at the sake of driveability...

Like I said I like the sounds and smell of a really hot cam doing its thing. It reminds me of the Can-Am and Trans-Am races I attended as a boy. I am not completely sure but there may be a connection between the "problem" you are having and the timing you ended up running. I remember you were considering somethinh over 38 degrees.. Where did you fianally end up? Have you tried dialing it back a bit??

I won't make quite as much power but it might help your situation..

Regards,
