Ron, Sounds like you have the same plant as mine: 400, 6X #8's, 600 Edelbrock, Performer intake, cam and HEI, 2.78 open [was a 2.78 but now 3.55], TH350 Trans. With that old setup I ran 15.02. Car was tuned pretty well but not perfect, Late OCT and about 60-65 outside so the air was a bit better. Havent ran since I put the 3.55's in.
