I'm in the process of putting a blower motor together and would appreciate any input as to the combo. 40 over 350 SRP Forged Pistons 20.4 cc dish H beam Rods with ARP Bolts Forged 3.75 stroke crank with 1/4 in. keyway Brodix IK 200 heads 72cc Doug Herbert roller cam Adv. duration 280 int. 280 exh. And at 050 it's 240 int. 240 exh. Lift is 555- 555. LSA-112 Dyers 6-71 blower 2 660 Holley carbs Rotating assembly is internal balanced This engine is going into a 66 Chevelle that weighs about 3200 lbs with 430 gears and either a turbo 400 or a glide, haven't decided yet.Only thing in question is the cam, wish I would have put a little more thought into it because I don't think that is the best choise for the combo.
