Building a a 400 to 512 to go in a 68 Charger with auto. I would like to see 600-650 HP and 700 torque. TF 240 heads, TF intake, 1 7/8 headers with 3 inch exhaust. Street car only, 3:54 rear. Super Sniper fuel injection with Hyperspark distributor and matching ECU. Car has power brakes so I need vacuum. Talking to Comp today and tech recommended a 23-712-9. I 236 and E 242 at .050 with lobe separation of 110. Comp recommended this cam custom ground with lobe separation of 112 and 4 degrees of advance built in. Comp says this is good 2500-6200 RPM. The second choice is Crane 689551, I 234, E 242 with 112 lobe separation. Crane says 2600-6600 RPM. I would rather see less HP and torque than to have to big a cam for the FI tune. Your thoughts
