Gear combos for the 1/4?
[quote="zipper06]
I run 5.43 gears with a 3200lb car 1.41 60' and run 124.85 1/4 with 14X32 tires. someone told me about 1 hr ago i can't run the QTR. with 5.43 gears, i said come watch. What RPM am i crossing the finish line, i don't know, probably 7500/7800, but it's still there for next round if i win.

Can't run 5.43's in the 1/4, HMMM?
Well, 20 years ago, my ChevyII, 336ci, Lunati roller, 750 carb, Brodix heads, steel crank, steel rods, speed pro pistons, TCI powerglide, 8" converter, 3300 lb car w/driver, 5.67 rear gear, 14x32's ran 10.90's @ 122 all nite long. Ran that combo for about two seasons before we quit racing. It would run 6.7's in the 1/8. Still have it all.
I'll give an even more insane combination. In the late 70's, I ran a stock 67 Mustang, used a good top loader 4 speed, had a Weber pressure plate, Hays clutch, Weber 50lb flywheel, 57 Ford 9" rearend with a 5.67 gear. It ran low 8's in the 1/8 mile with 10.5x 28 slicks. Car left hard, did run out of rpm on the high end, LOL!
I plan to do a somewhat similar set up with a later model Mustang, only plan to use an automatic with a 9/10" converter, if I can ever score one I like. Probably dial the gear back a bunch, don't believe the 8.8's go quite that deep, yet.
