[69 Mach I]

Before you settle on that cam and carb, you should fist flow the heads and then decide on the right components. I am rebuilding a 351W right now. I went with Windsor 200 Alum. heads that are mated to Hedman long tubes. My shop had them ported and flowed and then, based on the results, had a custom grind cam done up and mated a holley 650 double pumper with mechanical secondaries. I went with forged eagle rods and forged pistons. Since 98 octane is the standard for high octane gas, I opted for a 11:1 compression ratio. You should very easily get 400 bhp out of your set up.
