nitro question

i am building my engine its going to be a 383 stroker forged with new 200cc heads and rrs and 58 mm throttle body .. how much nos can i shoot to it ...i currently have 150 how high can i go??

Need more info on the set-up. 2 bolt or 4 bolt main caps? What rods & pistons?

also, is it LTx based or LSx based. it seems to take more work to run alot of dope on LSx engines than LTx engines. LSx engines like to stretch head bolts and pressurize the coolant system when it gets a 300hp or more shot of the dope.
