Did you want to know the history of boxes used or did you want to know what you can use today?

Note of interest: The M22 Muncie behind a small block is just about the sweetest sounding accelleration noise available to the human ear. The straight-cut gears make a whine like the cogged belts used to drive a blower. G-Force builds a T5 5-speed with straight-cut gears also.

I take it that all the 4-speeds are manuals?? Yes you are right about the straight cut dog box's making a great whine not sure If you'd be able to hear it over a throaty V8, I think i'll be going for a full twin stainless sytem with glasspacks.

I just wanted to know what box my 327 is bolted to at present as I wont know until I pull it out the car, Its a 3 speed auto havent really had a look round too much but I will have a look round for the engine number in the morning so we can norrow it down a bit Cheers!
