I am building a 632 Chev, on alcohol (injected), for a dragster. The car has gone 7.70 @ 170mph.Car weighs 2100 lbs, 4;10 gear, 33.5 X 16 X 15 slicks, usually , about 3700 ft air. 6500 stall convertor, 7400 thru the traps. Engine is 15.5:1, Brodix HH 383 CNC heads, reworked to flow 490 cfm ( 28") @ .850 lift . The two cams I am considering (car ran with 1 st cam)are , 1- 288* @.05, IN, 312* .05, EX..877 lift In, .817 , EX.LSA 116. OR second choice- 286* @.05, IN. 294* @.05 EX..875 lift IN...800 lift EX.114LSA. Both have 7/4 swap. I am leaning towards the second cam, mostly, with the idea of closing the intake earlier & get the cranking comp up from 180, to maybe 240 or so. Also trying to keep some of the heat in the motor, by shortening up the EX dur.Am I on the right track? Headers are 25' long pri, 2 1/4 -2 3/8 step, 9"merge collector. Any opinions, OR experience will be greatly appreciated. Thanks for the help
