I'll be putting in my MN12 fairly soon, must admit I'm excited about it.

I wouldn't start in 3rd for a roll unless it was 60+.

Your car should be good at 30, 40, and 60 rolls.
Ah, the 3.23s explain why your car probably doesn't wind out ridiculously fast like mine does. I'm sure it's a totally different animal with the longer gearing.

Sorry about the anger in the previous response, too. I was pissed off and venting it all out on LS1Tech.

No problem, I'm sure it is completely different. I can't say that I'd enjoy your setup though, it honestly sounds incredibly frustrating. I'd sincerely consider dropping to 3.73 or 3.42 with this tranny. I don't think I'd ever go higher than 3.73 because of the problems you're experiencing with the incredibly short gears.

Yeah, I've got like 2 weeks to figure out what cam I'm using as well as what tranny so it's pretty rough here. I'm not even sure if the ms4 is the way to go. I'm really going purely for street fun. I'm wondering if all the power at the very top is the best idea from the ms4 or if I should get something that spreads the power out. so many questions.. so many questions.



Quick Reply: M12, or T56 for my set up?
