have heads/cam and all that good stuff,
6 speed on et streets, took to track and pulled a few 1.90 60' ft. (needs tuning) !!

still running a completely stock rear end, i have a brand new 3rd member sitting in my garage in the box, (factory replacement) if my rear end were to break, it would be my ring & pinion usually right? so if i wanted to make it a little stronger could i put gears in that new 3rd member and stick that in there? what is the best brand of gears? i have 3:42's now and would only bump em up to 3:73's. what brand should i get? and do gears come with ring and pinions or do i need to look for that seperate? i've never messed with rear ends so i dont know,
thanks
