The old combo in my Duster was pretty similar to what you describe - with the .557" cam and 1.5 rockers, stock stroke, unported W2s with TRW pistons, Edelbrock Vitor, 750 DP carb, TTi 1 5/8 step headers with full exhaust, 4.30 gear it went a best of 11.97. Car weighed around 3,200 - full interior, no roll bar, flat steel hood. 275 drag radial and FMVB 904. Shifted at 7,200.
