wideopen231:
Building 526 TFX Hemi for my FED.Have been playing with desktop dyno.Normally its pretty dang close given correct info. Seems its estimates are high this time for what I would expect. So lets get a few guess as to what yout think out put would be.
4.310 bore
4.500 crank
7.196 rods
13:1 compression total seal low drag rings
BAE heads fuel style 2.375/2.00
stage 5 roller rockers
Sheetmetal intake w/
enderle injection
mag 12
282/278@.050 116cL .800 lift roller cam
give it a shot winner gets high 5 by the way.Down side will not know for sure real answer for while but maybe idea if I am off or program is off. Heck hopefully me.

go a head and make a SWAG guys.Not like your going to be called to front of room if wrong,heck no wrong here since true answer is not known yet.
Pipe Dreams:
I'll play along. Say........ 950ish.
wideopen231:
well pipe dreams I will say you are closer to what I am thinking than what computer program says Hopefully we are both wrong when its actual dyno time.

Chris I don't know too much about those Hemi heads . Do you think that 2.0 hp per cube is reasonable ? My sons 572 big block with Big Chief heads is around 1000 hp.Most of the comp stuff is up around 2.9 today .
