manual trans ratios
 
Let me hear about your four speed manual trans ratios.

My application is local brackets in a 3050-pound door car. The engine is an LS series small block, 372 C I. Sweet spot range for the engine will be about 5400 – 7200 RPM. I estimate the engine will be about 525 – 535 horse; performance will be low 10’s.

Rear tire will be 29 X 11, rear gear 4.88

I plan to use a Rob Youngblood Advance Clutch system and a G Force, four speed.

Thanks
Larry Woodfin
