Chucky is this helping

i was just thinking that...

what i would do is get a good tach... see what your cruizing rpm is @ different speeds...

this will help you fibd what rpm the engine is happiest..

then get a tire and gear combo to keep up with your hwy speeds and your good to go... but over 55/60 you'll start hurting milage
