At 70 mph my 94 GT runs 2380 RPM with 3:55's somebody post the 3:73's info please Oh yeah T5 manual trans,.
I did some searching around and I guess with a stock engine 355s are perfect for the T5 tranny. The average street driver would not even notice 1 or 2 tenths. The time differences between them would be negligible and that the 3.55s also have their advantages over the 3.73s depending on where or how the person drives.
3.73 will be reving pretty tight by the time you hit the end of the track. 3.55's will allow a couple hundred RPMs of breathing room before having to shift into 5th. .08 difference is less than a tenth if one had the OEM 273's or 308's then pick the steeper ratio.To change 355's to 373's would be a waste of money when talking about a street car application.
410s would give you a really short 1st gear... if talking about the OEM power band it will be short but If you got h/c/i which extends the power band ... it becomes longer
