Default 370 vs. 408 stroker????

I am considering a 370 combo with the following internals and I need everyones help with making a decision.

370cid+JE forged FSR pistons+Oliver Billet Rods+New Factory Crank+Calico Coated Clevite 77H Race Bearings+ARP Main/Head/Cam Bolts+Titian ICS Copper Head Gaskets+Stage II Heads w/titanium retainers and Dual springs+comp cams roller timing set+roll master dbl roller timing set+como cam 232intake/224exhaust @0.50 w/.575intake and .566 exhaust valve lift. Lobe sep is 115 installed at 112+CNC Cast Iron Block at 10:1 compression.

versus a build for a 408 stroker to fit in a 1995 SS Impala.

What possible RWHP do you think the 370 above will make and possible RWHP w/a D1SC pushing 15lbs.

Would I get close to 450RWHP on the motor with a 370 or 408?

Thanks a million,
Ron

You're gonna break 450rwhp with the 370, and you're definitely going to break it with the 408. With the 370 and those mods @ 15psi, you're probably looking at 750-800rwhp. With the 408 around 850rwhp.

BTW - People say the D1SC blower taps out around 750-800rwhp, so keep that in mind.
