318 Power, with real street manners ?

Shouldn't be that hard to figure out a combinations. Mild combos with 215 @ 0.050" and under are hard to screw up. Dual plane 600-750 carb 8.5-9:1 cr duals maybe headers done. Any real serious build find a good builder and come up with a game plan.

Its the mid level ones are a little tricky.
750 airgap and headers are pretty much standard. Leaving heads to be OOTB Eddies or Eq or port stock basically 230-260cfm.
Leaving the only real decision cam cr gear and stall which all have to work as a package. The cam is probably gonna fall between 225 - 235 @ 0.050" . Which is gonna narrow cr to 9-10.5:1 depending on cam and heads. And gearing and stall are gonna be based on a huge amount of factors but most seem to run 3.55 with a 2500 plus stall. Basically we have one combo :)
