360 and a blower

With him recommending it, there’s nothing better for your setup for your intended goals. That whole setup is going to be a lot of fun. It’s should work well enough long enough that you may not ever see the need in the big power blown RB. I would like to see a pair of 4150 DP’s or a single dominator, though. There’s almost no such thing as too much pump shot with a supercharger. It’s a lot safer than not enough pump shot with a blower.
I figured the cam I had is very close to his recommendation, so I used it.
I do have a pair of 650 dp holleys I'm thinking about using. The blower came with the Edelbrock linkage and I have two good working carbs so I'm going to try that first. I still may get the holley linkage before I dyno it and do both sets of carbs.
An if I really feel like dumping in air, I have two 800 holley double pumper as well.
