The 350 i'm finishing has an expected 425-440 ft/lbs @ 4500. To help w/ fuel milage i plan to mate it to a T-5 or T-56, that I'd rebuild. Are there any internal components to beef up the T-5 or an LT-1 T-56 on a budget?

 

Yes, but they won't be cheap. There are variuos parts that can be changed with the parts used in the Viper transmission. That aside, the stock T56 can pretty much take what a 350 inch engine can dish out.

 

Can the stock LT1 T56 handler 440 ft/lbs?... i thought it's rated @ 400 ft/lbs.
