all u need is a 302 roller shortblock from 86-01 dude then get the 347 done and swap parts from the explorer

if you go with a 347 regular GT-40 heads will not really support that much motor. they will either have to be ported or step up to a set of aftermarket heads. You could run un ported GT-40s but they will not flow enough to feed the motor effectivly at high RPMs

If you're going to buy an engine kit and start from scratch (i.e. no reuseable parts fro ma previous motor) then a 351 based stroker will give greater bang for the buck

400HP is about the limit for unported GT-40 heads with a 347 or 351 and a reasonable street cam. Nothing wrong with that if you throw a 150 shot on top of it.

Less than $1200 for a balanced forged piston rotating assy.
