Me too, hopefully you can get to your 470 pretty soon. The cam is from Hughes, I bought it 2nd hand from a member here. What were you hoping to do for intake and carb ?
For my build, I was recommended something in the 260's @ .050 and around 0.650" lift, so similar to yours. I've got a Victor 383 intake and a few 4150 carbs to choose from (2 different 950's and an old school Holley 4781 850).
