What gear ratios are you running for 2nd and 3rd, and Ring and Pinion (LS1 guys 350-450 horse)?

Not sure on gears but when McMullen rebuilt my 2d he changed the R&P from 514 to 486. Made my spyder nicer to drive. You can now go more than 10 feet in first without banging off rev limiter and second has a bit longer legs.

I would call Kevin McMullin. He is a stand up guy. He will tell you what you need to be running. Plus he rebuilt mine in 7 days.
