383 Combo Suggestions

I budget-built a '77 cast crank 400 from a Newport using the complete engine with a deglazed bores ring/ polished crank bearing job, good valve job and some select milling. I milled the 452 heads .060" on the deck and .072" on the intake face (so any unmilled intake would fit perfectly) to up the compression substantially. I also used the .018" shim head gaskets, and the pistons were whatever abysmal negative deck they came with. Used drop-in Crane single valve springs (roughly equivalent to Comp 911 springs, I had them laying around) and a Comp Cams "Dual Energy" 275 cam (still available, listed in "specialty cams" section of the catalog) with 219/235*@.050" duration and .462/.482" lift, 110LSA. With a DP4B intake, 750 AFB carb and HP manifolds with full 2.5" exhaust and Hooker short turbo mufflers it was a beast (at least per dollar)!! I had it in a Challenger with 3.23 gears and a factory 11" hi-stall converter (2400rpm?), and people swore it was a 451. Sounded lopey but pulled from pretty much idle to 6500rpm effortlessly. I love that combo!!!
