512 Stroker

I think the heads you plan on using will be what holds you back. I wouldn't use those heads with a stroker build. you will need some decent flow to make power with that stroker.

this is interesting reading. I`m expecting much more power out of my build that what your after.
.030 over 440 block-4.250 forged crank-dished pis.72cc alum heads,fully cnc ported,.039 head gasket-.620-.628 lift 254-260 duration @.050,street roller-all the normal tricks w/ stud girdle on the bottom end. the big problem I see coming is, it doesn`t look like it`s going to fit under my 6 pack scoop. thinking about dropping back to the shorter torker 2 . haven`t made up my mind about carb or fuel inj.(pricey)expecting around 700 h.p., 650ish torque. (all comments welcome on this, good or bad)
hopefully about a 3000 lbs. 68 barracuda street car, w/ 373 ndana 60-727t.f. in it 10x28 drag radials. comments?---( never too much h.p.!)
by the way "fast 2 fuel inj." now good to 1200 h.p. ----bob
