i have the block and im trying to get 12-1 compression and can i have some nitrous on top of that, im going to sleeve the block have to be a street car have to drive it to work im going to get a jg head need to know how good is that head for a street car. the best place to get a LSD transmission thanks for the help

 

Good luck running 12:1 on pump gas every day. It's possible, but tuning is gonna be a bitch.
I don't recommend going over 11.5:1 on a daily driver.
Check with http://www.hmotorsonline.com for a LSD transmission. They go up for sale on here from time to time as well.

 

Have you done much research on your own? Your questions seem so vague that I'm guessing you haven't.

 

i have done some research not a lot thats why im on here asking some questions
