I am wondering where I can make some more power. My engine combo is: 350 stock bottom end 4 bolt untouched; had 8.3:1 original compression with 76cc heads AFR 0916 180cc Heads with 65cc chamber making 9:1 compression; I am measuring 150-160 cylinder pressure. Comp Cams XE262H Xtreme Engery cam; .462/.469 lift, 262/270 duration, 110 lobe seperation 670 Holley Street Avenger dual feed, vacuum secondary Edelbrock 7101 performer RPM intake 1 5/8 headers, 3" collectors, 2 1/2 dual exhaust with converters 1.5:1 rockers Timing set at 12 initial, 33 mechanical all in at 3000 Stock stall converter with TH400 trans 342 rear gear, 26" tires 77 camaro, 3500 lbs running 14.1 at 99mph I figure the engine is making just about 300hp. I hoped this combination would make 350 or so. My goal is low 13 1/4 mile. I am thinking not enough cam. Considering 1.6 ratio rockers. I did reuse the original timing gear/chain set which looked like new. I am also considering new timing set and installing using the 4 degree advanced keyway. Any thoughts about the combination or what I might change?
