I'm interested in the quareter mile times and engine, trans and rear combinations people have out there. If you don't mind, I'll start us off with a combination I had, and we can see where this goes!
Performance: 11.20 seconds at 120 MPH in a 67 Skylark, shift point at 6400 rpm, 100% racing gas used, road legal and driven 30 miles to local track (most times driven home as well).
Weight: 4100lbs. with X-large driver and cage.
Engine: .030 over 455, 12.5 to one J&E pistons, 0 deck and O ringed block, Oliver 4340 rods, TA block girdle, BHJ balancer, TA flexplate, TA 610 cam in at 4* advance, Gessler ported competition Stg 1 heads, flow and port matched SP1 intake, Kenne Bell 1.6 to 1 roller rockers, HV oil pump.
Trans: TH 400 with 10" ATI converter. Converter was made loose to flash stall at 4200 RPM.
Rear: 71 12 bolt posi, Moser axles, C-clip eliminators, 4.10 gear, boxed lower control arms, polly bushings, no hop bars, air bags, sway bar and stock application gas shocks. The 60' time was a best of 1.55 seconds, and The slicks used were 28" tall x 10" wide.
Exhaust: TA 2" headers, 9" collector extensions, GSCA 3" exhaust, TA large case 3" mufflers. All 1/4 mile times were through the exhaust.
Fuel System: 1/2" fuel pick-up in tank, 1/2" fuel line, Mallory 140 filter, Carb Shop ultra blue fuel pump (modified holley blue pumped 143 gph at the carb end of system), 1/2" carb spacer, modified 4781 850 cfm holley flows 990 cfm, drop base K&N sealed to cowl induction hood.
Ignition: Stinger magnetic pick up conversion, MSD 6AL ignition box. The distributor curve was 20* mechanical advance at the crank all in by 2500 rpm. It liked 29* total advance. The system was OK, but did have some timing bounce.
Front end: 1 1/4" sway bar, 255 series tire, street alignment, standard application gas shocks.
The street compromised front end and rear shocks, the too loose converter (9" would have been better) and complete exhaust system were hurting 1/4 mile performance, but it was still pretty nimble on the street. 3.55 gears were a much better street gear, but cost a 10th and some over the 4.10s at the track.
