It had been a wile since the 4.10's were in my car, and I need to know at what RPM in 4th are you going thru the traps at the end of the 1/4 in??

I cant remember, and I am having a new rear built, and trying to decide on 4.10's or 4.30s.

 

About 5500rpm with 26" tires

 

james.. my time is sig was in 5th gear lol.. sucks when you car falls on its face at 5200 but NA, I would finish around 5000 +/- a few hundred RPM's.. All my times where on Nitto 275-40-17... i guess weak vavle springs, and bent valves will do that.... oh well its all new on the new heads!!

 

I would go 4.10, that leaves a little room for some more MPH, should you get some more mods, etc.. 4.30's are overkill I think.. It's all about MPH, not ET.. hehe.. I would opt for the 4.10's there buddy..

 

yep... 5500
