I purchased SPF 2378 from Dynamic in Reno. Great experience dealing with the folks there, I purchased the polished Roush 427IR and had the TREMEC 5008 which had a higher 5th gear in it. Would not recommend this transmission for your application, the guys at Dynamic and Steve at R.E.D can work out the details. I trusted their recommendations and couldn't be more pleased with the outcome, go with what they suggest. Steve at R.E.D did a superb job on the installation and all the tweeks that go into making everything work. Still breaking the car in so I can't give you actual details on performance. I have two Porsches one that puts out over 400 HP (RSR) and I know the SPF will outperform those cars. I haven't driven the RSR since I bought the SPF.
