i have an 89 5.0 that use to be a 4cyl and judging by how much torque i have it seems that i have around a 2.76 rear end. i was wondering if anyone knew how fast i was going bc my speedometer only goes to 85.

i was in 4th gear busting it into the powerbands , my speedometer was stuck on the odometer reset, and i was hitting around 4500rpms. does anyone have a clue on about the speed i was running. i had a friend say about 120 but i dont know what hes going off of

 

105

 

thats even with maxing every gear?

 

yah, stock these cars top out abuot 130, and even that takes a little while. i recently did this on a local straightaway here(RT83). 4000rpm in 4th, i was doin 100-105

 

so 105 eh it felt like i was flying lol the car was actin like a dream

 

be careful with stock brakes doing that. i found that out the hard way. stock replacement rotors are junk at that speed. they heat up so quick that they actually warp as soon as you hit the pedal. violent shaking stops are scary.

 

i would have to agree with that... i have 2.73 with a t-5 and at 4000 in 4th im just under 100 idea say... so 105 seems bout rite... there are calculators im sure some1 has a link to one that will calcuate processly if its important to be completely sure

 

my car, stock, runs 136mph at about 5500 in 4th gear

 

you need tire diameter to be sure
