I know the most N/A RWHP out of a LT1 is about 400, maybe 415 if you have a really good set up. I was wondering what you are seeing out of your 383. I was trying to determine if it's worth it. Also, how much $ do you have in your engine. Thanks!

 

I'm sorry, my numbers were for 350 cubes. So it's not out of the norm to get 550 to the wheels. Cool, thanks man.
