GT40 Lightning PU--Now what

Hey guys. I have two 351 Lightnings (93'&94'). Both will be approached differently, but, the 93'model is down for a head gasket and won't go together until I decide what to do with the performance issue. Basically, I want to do everything reasonably possible for better perfomance, but to stay with pump gas (89-93 octane) the EFI and intake. This includes potential stroker kits. My problem is that I've never dealt with the 351, and I don't know where its limitations are. The EFI has a Ford SD to MAF conversion, but nothing else, except that the headers appear to be Bassini-type. The pistons are stock low compression, and the valvetrain has roller rockers, and a hydraulic flat tappet (probably stock). I do know that Ford kept the compression low (8.8, I think) and that the cam is a very lov profile, probably less than "RV"status. Obviously, I need to change cam/pistons, but, I don't know if the GT40 head and intake will support more cubes, if I go stroker. Any thoughts and ideas are greatly appreciated.

Re: GT40 Lightning PU--Now what

They should, but if you're stroking the engine, you might as well have the heads ported.

Ever notice that there's so many high performance parts available for GM products?

Did you ever think that maybe they NEED them?
