Lol! its those fond memories that make life so great!

I've always wanted to try one of these out, theres guys using the similar peanut port heads in gt with success, and they have proven to work well on on street engines. I even know a guy that made 450hp with them and got 26mpg lol. The throttle body on the 454 is rumored to flow around 650, should be enough for a 5500 rpm engine. Factored at 310, while the comparable 1975 carb engine is factored at 320, with a little worse head. Also dosent weigh much more than a big block chevelle!

May not be dime 'rocket' status, but it may have potential.
