Id say yes but i wouldnt use too much as stock motors arent built for the higher temperatures and more power. but if you only use a low shot it should hold on for a few races. its a chevy so you know its built good
first of all why?!?!?!?! if you wanna go fast, get a real car. plus NOS isn't good for any engine if you use it enough. it burns really hot and if it gets too hot you could blow some peices.
