Hi guys,i did a search here on my question but didnt find anything so here go's.
Can anyone tell me what approx cruise rpm would be @ 60 & 70mph in 5th gear with 2:73, 3:08 & 3:55 gear ratios for my 91 5.0GT 5SPD with stock 16" tires?
Also need to know what the correct speedo gear would be for stock oem 2:73 & 3:08 gear ratio too.
Reason i am asking this is i recently bought 91 5.0 that looks to be bone stock but it seems to be running considerably more rpm at cruise speed then i think it should with oem 2:73 or the optional 3:08 ratios.
So i looked at the rear end cover it seemed to have bolts that dont look stock so maybe someone had the dif cover off to change the ring & pinion.
I also did a quick check to see how many times the drive shaft turned for 1 rotation of a rear wheel and it was approx 3.5 turns of d-shaft for 1 tire rotation so i figure 3:55's might currently be in the car.
Thanks in advance for your help.
