512 cam selection, what do you think of these options.
I have a 512 in my Duster with ported aluminum heads (roughly equal to TF240 heads). The other specs are kind of the same, I'm around 10:1 compression with 1 3/4 headers. I used a hyd roller cam with 246@050 duration. It has just a bit of a rough idle with a carb but with EFI I can tame it down a bit. It makes 600/600 on the dyno so plenty stout. The point is that you don't need a big cam when you have good heads even if the engine is 512 inches.
