I have a Barracuda too! It's a 68fb FormulaS clone. It has a 367LA, a deep-low A833,a GVOD, and a narrowed 8.75 with 295s in the stock tubs, which have seen 325/50-15s in them. The fronts are KHers with the 4" sbps.
I too love this car style. It was completed in fall of 1999. I was 47 that summer. If you have questions you can PM me. My chassis, in the last 18 years, has seen all kinds of trannys and rear ends and 2 SBMs and several cams. I have never had a BB, but once did dream about a 400low-decker, with maybe a bit of a stroke. Since you already have the parts, I'd be leaning in that direction.
But, Mr.Happy, have you considered a turbo car? With your mechanical skills and experience, has this idea ever crossed your mind? If you brought this to completion,you would be one of the very few. I think the 360LA could make a dynomite mover. Even a teener could be more than enough for a streeter. The 360 tho,could be built to hit bigger trapspeeds on less boost,and would probably be a bit better out of the gate.This has always been a dream of mine, but at 64 this summer, I have all but given up on that one.
