I ran almost identical combo!

Jim your combo looks great especially with street driving in mind. I ran the same pistons and the f-,246 cam Torker and tried both 850 and 750. The trans I had was c6 and 28 inch slicks and 514 gear. The car ran 2mph quicker with 750 carb, giving me a best of 12.80 at 107 so as you can see by my mph I should've been able to go low 12 with some suspension work. I never dynoed that combo but I figured about 425 flywheel. I regularly drove that combo 60 miles or more at a time. Your car with t5 will free up power and your about 200 lbs lighters than I was then so that will help.
