Hello from BluePrint Engines!

still working out some variables. may end up going 4 speed...auto
Good modern converters aren't cheap though either. Dust your wallet off and make some calls to dynamic, ultimate, PTC, etc.
yup

Mopowers is correct. The generic answer is 1800 - 2400, BUT....you want a custom converter made..
agreed, and they're going to need gear ratio, car weight, intended use, ect

..I'd suggest dont under stall, just call! (a converter company!)
:)
thanks
