Safe Rev Limits and Valve Float?

try a 3.73lsd

for a 7500rpm redline you'd need a schrick 288 or 304. no point in going much past 6500 with a stock cam.

stock (new) springs start to float past 7200 in my experience. haven't had any trouble with the rockers. if you have an original head you probably don't want to turn it that high either, as it will float earlier and break rockers.

old head, new rockers so float above 7k could be an issue then..

DIE 3.73 nazis DIE!! 4.10 FTMFW!!

RE: gearbox, its an 89 325is box with slightly overdriven 5th, not quite 1:1 in 5th with the 4.10.
