Best 273 and 318 builds (NO 360's please)

My IDEA.. a 273 - The stock forged crank
I have a set of good 1970 340 rods - a good set of forged pistons (www.flatlanderracing.com) - LD4B intake (a-body hood clearance) - Avenger EFI throttle body kit - 70's 318 heads with the 273 adjustable rockers - Comp Cams xs268 cam - topped with a Procharger @ 6-8 psi to make up for the low comp.
