My dad has an 82 vette with a ZZ4 engine in it with a Holley 650cfm 4bbl, Edelbrock performer intake, and 1.6 ratio rockers on it. Also has Dynomax full-length headers with a 2.5" true dual system on it with Ultraflows and an h-pipe. We've been considering strapping a nitrous system to this thing for a little extra "kick". I was wondering how well this motor can take it. For the nitrous to be worth it, we'd probably want to get a 100-150 shot out of it. All replies appreciated.

 

You should be fine, the ZZ4 has a forged crank in it. I run one in my LT1. I wouldnt worry one bit about spraying a ZZ4

 

With a aftermarket pump and a good dyno tune you should be fine with a 150 shot . If the motor has a forged crank as stated above.
