That was a great running car! What was the whole engine combination?

It was a stock 5.0 block, with a 3.25" stroke Eagle crank and rods, with flatop pistons. Cam was a solid flat tappet Comp Cams (.560ish lift, 252@.050 duration), out of the box AFR 185 heads, Victor Jr. intake & 650 DP Holley. Set of cheap 1 5/8" FlowTech long tube headers, Used a Jerico DR4, and 4.88 gears in the 8.8, with 9x29" Hoosier slicks. Dumped the clutch at 62-6400 RPM, shifted at 6800, 7000 at the finish line. Now running a "big bore" 347 SBF, (4.125"x3.25", Dart block), flat top pistons, smallish hyd. roller cam, AFR 185 heads, Parker Funnel Web intake with a Holley 750. Same headers, clutch, but switched the Jerico for a G Force G101A 4 speed, gone a best of 10.01 at 133 mph in my 78 Fairmont (2900 pounds), bracket car, still mid 1.3 60 foots.

Got in some better air, 260ft da. Went 10.32@131.31, with 6.59 eighth@105.4. 1.43 60 ft. Still need the converter loosened some. Going to run some valve lash loops, and try some thinner oil for the heck of it next time out. Not enough time in the year to send the converter off right now. Maybe get a mid 20.
