That's what I run in my street driven moderately modified 306 / C-4 / 3.25 combo. It's just right for me. I do run 1.7 roller rockers though to give a little extra valve lift (.486 vs .456). Good pwer from idle to 6000 RPM with a standard Edelbrock Performer intake and a 625 Road Demon and Tri-Y headers, 3 chamber Flows, 2.5" exhaust..
