    350 drag race chevy engine

    I am building a 350 bored .060 over 4 bolt main for a 1500# altered. What do ya'll think of this combination. 3.48 crank, Eagle 5.7 H beam rods with L19 bolts, 12.5 to 1 CR, topped by AFR 220 Competition Heads with 65cc chambers, with Comp Cams solid roller cam with 284/292 duration at .050 lift, and 680/660 valve lift and to top it off an Edelbrock TR-1Y tunnel ram with 2-660 Holley's all fired by MSD and exhausted thru Dynatech 2 in primary's with a 3.5 inch collector. Also, the cam is on a 106* LSA.
    How much HP and TQ should this combo make, and what rpm will it make max torque and HP? I understand that I will have to spin it to 8000 to 8400rpm to make it all work on the track. Also, what ET's can I expect with this combo with a 1.76 Powerglide and 4.56 rear gears?

    I would guess mid 9's with everything running right on gas.
