My brother is building a 440 for a 69 valiant we recently picked up and he had started building this engine awhile ago. The engine is a 440 block .40 overbore, arp main bolts, LY rods, keith black forged flat top pistons, no cam yet but thinking conservative solid roller around 250 @ .50 and .620 lift. edelbrock victor heads standard port not max wedge, comp 1.5 offset rockers, m1 single plane intake, hooker super comp fenderwell headers, no carb yet,or ignition, 3800-4000 9.5" converter he has and 727 manual valve body, 8 3/4 rear spool 35 spline axles and 3.91's. He has most of this stuff already. Guestimate on horsepower and any suggestions on other opinions would be appreciated.
