Dunno about the particulars for your engine, but it sounds about right . .
Heat's OK, E.T.s consistent. It's a "Bracket car" . . Got any idea of what your EGT was? That'll tell you a lot when tuning an alky car . .
But I don't have much Eighth Mile Experience, and what I have is with a Blown 540" Aluminum "B" Mopar in an Altered . . So anything I come up with is probably a SWAG . . .
Personally, you seem to be doing pretty shiny . . Keep it up . .
