Okay my plan is for the first real power adders are these heads SUM-152123 and this cam Comp Xtreme Energy Camshafts 08-502-8 then when i have the money i am going to get a supercharger from procharger, how much power would you say i could make n/a and boosted just asking?

Why those heads? Those are basically new camel humps or whatever. What intake manifold? Prolly wont make over 220 whp with that cam but with boost i can see 100-150 more hp reliably on stock blocks
