On the summit racing website, they have the LT4 conversion kit for my 95Z28 and claim to give it 425+ hp. My car is completely stock, so what kind of realistic gains could I receive from this conversion?

 

please do a site search this same exact question was asked not one week ago. youll find lots of info and opinions on the conversion in this forum. IMO its worth it, but read on and see what other say and form your own opinion. Trey
