393 head question...
I am in the process of collecting parts and designing a 393 to be put in a '68 EB. My truck already has a 351w in it, so I'm not concerned with the swap issues. I will be looking to build the motor at about 9.5:1 compression, with a roller cam and rockers. I was thinking about doing this as budget as possible, so I might go with a set of rebuilt gt40 heads with a homemade port job.
I am "only" looking for about 350 horsepower, with torque to match. The engine will eventually be Mass-Air'd. Would these heads work for this combo or should I step up to some Roush 200 or Windsor SR.? Would I be better off saving my $$$ and using a flat tappet cam? Any help would be appreciated...
