say if i added 100 hp with a topend engine kit to a stock (and i mean stock no exhaust and intake nothing) 1990 mustang 5.0L(not cobra) what do u think it would run in the 1/4 mile
What does your topend engine kit include? And how do you know it adds a 100 hp with a stock intake? A stock cobra only flows well to 400 hp. Need more info before you can estimate 1/4 times. If you just want numbers use a quarter mile calculator.
it will go faster than that. i ran 12.60s in my GT with ported cobra intake, B303 cam, GT40 iron heads(NOT THE P HEADS), 3:73s and some other dumb shit. all done on a drag radial. i couldnt even drive that well back then i was 16!
