I really want to be able to use 5th & 6th without worry. Does anyone know of an economical way to get a 1pc countershaft into an F body? I'm considering a T56 Magnum since it has one along with other upgrades but that's not a direct swap. The F body T56 Magnum is too expensive, any ideas/thought/input?

What kind of power is your car making?

Initially a 425-450 rwhp turning up to 7k rpms. Later I'd like to push past 550 with a stroker. I'd really like more rpms as well as the ability to use 5th & 6th. I know that some use them with a 2pc countershaft without issue while others have had problems. I would like to be worry free for my power level goals. I would not use nitrous in those gears either.

The only production T56 1pc counters were the early viper units, which Dodge/Mopar started refusing to sell without a viper VIN (and claimed to only work with a viper input shaft) and the '06-'07 Z06 units.

As I wrote in the SSR-Hybrid PDF, the Z06 1pc isn't so bad, but the unique 5, 6, rev drive gears required to use it more than double the pricetag.

Yeah the C6 Z06 cluster would be your best option but as said, you have to change out the 5-6 stuff that rides on it.

PM me if you would consider going 32 spline MN6 direct bolt-in.
