hi all, since my forged 4 valve block did not sell i have decided to keep it and use it for my next mustang. it is 9.5:1 compression with B heads. how much power would i expect to make at the crank approx if i used Ford GT heads, degreed 96-98 cobra cams, short tube headers (cali), 99-01 cobra intake with adapter, underdrive pulleys, catted midpipe and a tune on 91? how much would i make if i made the compression to 11:1? if anyone is wondering the internals are cobra 8 bolt crank, manley rods and manley forged pistons, however i was wondering if i should switch out the rod bolts, theyre arp 8750s.

I would venture a guess around 300-315rwhp....so about 360-375hp @ the crank

Engine Might have to get a Dart block but don't want to and if I do, then 363 instead of 331. Thoughts on what I've already bought so far.......
