well i was wondering if a m21 or 22 would have enough gears to get em the speed i want out of the car ..or should i just get the manual in it and then worry about boosting hp over 350hp to get the power ant trq to go higher gears to ger speed ....or if there is a 5 speed newer tranny that i can get to bolt in fairly easily ..i have been looking around and cant find a company that makes a 5 speed that is a bolt in for the 396....
