TH375/NP205 Combo?

[kwmech]

The 375 output shaft is too long for the 4.5'' adapter, and there is not enough spline to cut down. If you insist on running a turbo 400 you'll have to get the correct parts and machine the 205 case for the 210 bearing

Thanks everyone for the replies.

I couldn't find any info on the TH375 output shaft length, thanks for the info. I'm fairly sure a rebuilt TH350 will live behind my stock (aka weak) 454, but I plan on adding power in the future and I only want to pull the transmission once. Since I have to pull the engine and transmission before spring anyway I figure it would be a good idea to put a capable transmission in there now.

I scored an NP205 with the 32 spline input shaft and a TH400 adapter attached for a decent price, so it looks like I'm committed to finding a TH400 now
