right now i have a all stock 1989 305 automatic iroc with 2.73 gears in it and it runs 10.5 in the 1/8 mile and i have just recently bought some 3.73 gears for my car what do u think i will run with the new gears????


thanks.

 

About 4/10's faster in the 1/8th, providing you hook.

 

u running TBI or TPI?

posi going in w/ those new gears?

 

no i really do want to get a posi befor i put them in but cant find any for cheap do any of u know were i can find a cheap pritty good posi and i am running tbi

 

You won't be running anything unless that 3:73 gear set is for a 2-series carrier/or you have a spacer.

 

idk if it came with any of that how will i know i just got the gears and a master instalation kit???

 

10.50s @ Kennedale?

 

You will know when the person trys installing them. I take it you did not to much research on this subject. Good luck

 

yes at kennedale fast355 i guess ur from around were i live. do u ever race ur car there??? And when i orderd the gears the discription said that they would fit my car.

 

Good Luck....It should list something on the invoice what series carrier they fit.

 

i orderd the gears along time ago so i dont remeber what it said. will it say this on the box of the gears???

 

you should also get a detroit true trac LSD from drivetrainspecialists.com

 

Actually I am from Hurst and run a Fullsize Chevy Van at Kennedale on a few street nights a year. 350 TBI ran a 9.47 @ 76 last time I was there.
