im running a 327 in a 81 Z28
9.5/1 comp 218 dur cam with 454 lift
dome cast piston and cromolly rings
stock 76cc heads 194 intake and 150 exsaust
ran a 14.6 at 95mph
crank is cast 10/10 bearings
how much spray will it handle and how much will my
1/4 time and speed change

 

Sent you a PM.

 

just browsed your link but didnt see a kit for my car how much would i be looking at

 

I wouldn't run more than a 100 shot on cast pistons. The amount of time it will take off depends alot on how the car is set up and how fast you are going already. Nitrous works better with a little tighter converter, but I would expect .5 to 1 second time reduction in the 1/4 with a 100 shot.

 

I agree with not using more than a 100 maybe 150 on the stock cast pistons.
I would look into the NX systems for a great carburated plate system we offer several different catagorires that would work great for you.
I am assuming being a 81 you car is carburated.What carb are yoiu running.
Let me know if I can help.The NX system have the best product on the market and the newest plate desighn.

id suggest a nice plate system also, theres other ways to introduce nitrous into a carburated motor, but for a stock internaled motor id stick with the plate system.
