Just a 284-484?

15 X 3.5" Ansens, 4 wheel drum brakes, 6 cylinder torsion bars, 002 and 003 rear springs,adjustable pinion snubber, long shocks from parts store, worn out shocks front,manual steering. so why could his 360 not make 450hp? with enough time spend on the combo, don't you think it's possible? if my old clunker ran lo 13's with problems, what would a similar 360 short block engine with Magnum heads and air-gap be good for? 360 has more torque than the 340 to get it moving quicker, lighter pistons for quicker revs.anywho, thanks for letting me put in my 2 cents worth. will give refund with SASE. Thanks! BOb
