Just finished a DART 427 stroker. 4.185 bore x 4 stroke with 6in eagle "H" rods, mild cam (16in vacuum at 1000rpm, 21in at 1600rpm).
Running a Holley 4150 carb (750cfm) and Brodix heads, MSD ign.
75 square jets for a bit more fuel, mechanical advance in the MSD (18deg max movement) base is at 16deg wot 34deg. I will give up a bit of HP for reliability.

Dyno showed 502hp at 5600rpm. 521 ft lbs at 3600rpm. Torque curve showed aver 500ft lbs from 3000rpm on up....
Yes, the engine produces over 500hp, but more important to my requirement is that the engine will idle and be very drivable. I will have my 500hp, a very strong bottom end of both the engine and acceleration, but I have a reliable, driveable package that should give many happy years of service!!!!!!

MANY THANKS to Lee and the guys at Lab Machine in NY for building such a package!
