excellent information. you are correct on all counts. Nothing wrong with a zr1 4 cam. engine is best thing about it period. a real work horse and as stable as they come. Unfortunately, technology will eventually win in the end. It took me a while to accept the fact that the ls platform was here to stay. they make power, cheaply!! lots of it. I can buy a 376 ls3 crate motor pushing 525 horsepower for 6500!!! new. I can buy a supercharger for 5400 and push over 600 rwhp!!! then again, when will i ever use that? My only comment was to the gentleman considering a zr1 is to buy modded if he wants to be relevent and not get killed at every stop light buy mustangs....camaros.... late model vettes... challengers.....330-340 horse wont get it done any more. In the day, KOTH..today court jester unless modded.
