Thanks

Yes, that Tremec 3550 is a bit on the fragile side for the power your engine can put down. Most will choose a beefier Tremec TKO (it replaced the 3550 and was built to be stronger and smoother than the 3550) to bolt that engine to. What's the final drive ratio of his fifth gear? Should be either .68 or .82.
