at what rpm is the stock rev limiter set at for an 89 gt.. and what does everyone think of a safe rpm to shift at if im running it? it only has 56,000 original miles, just had the tranny rebuilt and was curious. Thanks a lot guys!

rev limiter is at 6250rpm...

and if your engine is stock, or rebuilt with stock parts... ~5200 should be your max

alright thank you very much... i kinda figured around 5, i feel sketchy going past that but im getting an msd 6al and i was gonna set the rev limiter at 5500 what do you think?

Really 5200? **** I bring mine up to redline a fair bit? Isnt redline 5700? Am I hurting my engine?

not hurting it yet but you aren't making any power.
stock 5.0 internals are completely done making power at 5250ish

the only thing you are hurting... is your times

does anyone know where i could get a picture of the stock hp/tq? and is there anywhere i could go to est. hp/tq with the installed parts?

AdderMk2

if you car is stock, chances are REALLY good that you arent making more than 200rwhp

and if you tell us what parts you are installing/want installed.. we can give you approximate gains
