4.5 bore and stroke ross 10.1 pistons 7.100 rods. heads are new iron heads that have been opened up. Solid roller cam 254 265 at 50 633 lift. roller rockers two 750 aed carburators on a opened up new cross ram intake msd 6al msd pro billet distributor and 10.4 mm wires I'm hopeing for 700 to 800 hp n tq what do you all think.

I hope you achieve your goals but 800 seems like a lot to ask from a pump gas crossram. I would expect 800 with max compression and a mod man intake. Good luck.

not enough cam or compression for 800 hp. torque around 725-750.

I'm not sure what the numbers will be.. but it'll be a beast on the streets.. good luck with your build

Probably more dependent on the head flow than anything. The last 572 MP Crossram Hemi I did had pretty mild aluminum heads that flowed 404 CFM at 28", a bit over 12:1 comp and a more aggressive cam, but it also made 915+ HP and 800+ TQ. Of course, an alum head 12:1 motor is closer to the equivalent of a 11:1 Cast iron head motor, so you are giving up some HP/TQ in both compression and cam.
