I’ve got a set of reworked cast iron Vortec heads, Edelbrock Comp intake, mild cam, jetted Edelbrock 600 cfm carb and long tube headers on a 307 in my 70 C10 ( all of which I had accumulated over the years except the cam and lifters that were bought new) A real budget build that pulled 300 HP on the best of 3 pulls on the dyno. If you’re happy with that kind of HP it can be done. You can get a little bit more HP but the bang isn’t worth the buck at that point. Small gains at big costs getting anything over 290-300 HP.
