Okay. I'll be using GLMs and stock risers which is why my cam specs are so mild. The motor will burn 93 octane because my cam will give a decent dynamic compression ratio (8.2). I won't get 490 hp...hoping for 415-420.

Thats impressive. And just 9.6:1 comp and a 650 carb. Those AFR 195's, are they the new ones that flow 300 cfm?

For the cam, how mild is "mild". I am building a very similar motor with a 214/218 duration cam with a 112 lobe sep. Curious to see what my combo might do.

Cool, thanks. Did you have to use aftermarket manifolds?

Yes, Stainless Marine.

Yep, #1034 AFR Eliminator 195`s w/65cc chambers, tried a 850 carb on dyno was 488hp but low end torque dropped off, so 650 carb was just right for this one.
