About the injectors. I dont know. I have a set of them that I want to sell but I dont know the info yet.About the stock internals. I saw a guy run 475 at the wheels for 3 weeks before breaking. The highest safe hp would be 425 at the wheels. I would not go above 400 if you really want to be safe. I am running 450 at the crank and 375 at the wheels. I am going to do an exhaust then build the motor after a year or so. I am a woose though and I really dont want to blow it up.This is just what I have found with my research and I could be wrong so other input would really be helpful.Thank youeric

Sweet! What have you done to make 450HP? Got any pics?

I will tell you like this bro I have seen a TON of Z's blow at under 400whp and seen a ton hold up to 500whp for how long its hard to say. I dumped my motor at 420 last april. anything beyond a SC I would get 550cc injectors or larger I am running 440cc now with a SC

but the stock internals suck on all Z's and its just a matter of time
