I Know this ? has been asked before, but can't find the post. Some racers are planning on going to the PUDUCAH INTER. RACEWAY in KENTUCKY. I'd like to go w/ but don't have a clue what final gear to run in a 355,3spd.,3080lb.,s/s? And is there anything I CAN'T OR CAN run?? I'll call the track but just trying to save some LONG-DISTANCE. HEHEHE
THANKS TERP

I have ran there with 305 hoosiers and I ran a 6:33 and turned 7000 rpm. This was their pro street class. The street class runs the smaller ump tires. I had a friend rum there with a 6:50 on the smaller tires. He turned about the same rpm if I recall right. Be prepared for black slick. It always gets that way for the street cars after the late models run. Good Luck. One more thing, if you intend to run street, you must weigh 3300 or you will have to run pro class against limited late models and 410 cu in.

i run at a 3/8 with long straights and tight corners. my car weighs 2800 lbs. and i use a 5.29 and turn 6600 with an 11:1 393 ford.

i like to use a taller gear beacause there is more speed potential. you have to be careful picking up the throttle so you don't get the tires spinning. with a taller gear, once you get them spinning its harder to get the car to hook back up.
