Just curious,I happen to have a new NOS plate system setup that I've had laying around(still in box) and was wondering what a safe amount of nitrous would be if I decided to use it on my 67 NYer with a 440. From the looks of the motor,the internals look to be in good shape and I plan on doing a compression test to see what readings I'm getting on all the cylinders.The mileage reads 44K miles and it appears to be original but not sure,although the engine did look exceptionally clean when I replaced the oil pan and valve cover gaskets,like it had been rebuilt.Has anyone here tried running NOS before on their 440 engine and how durable is it? I only plan on occasional use and am not looking to destroy the motor.Just wondering what a reasonable horsepower increase I might use above the stock rating of the engine without damaging anything.Any ideas?
