Since I need a new project I'm going to try a Double Pumper. I was leaning toward Holley since I have tuning kits and some experience with them. I'll be removing a 770 street avenger with Vac secondary's and was thinking a 750 Dp is this the best size to use. It's a 408 stroker with supposedly 520hp but I don't have the engine internal details.
