CFM??????????

Here is the Specs

Dart Small Block
427
20cc Dished Pistons
6 inch rods
Dart Platinum Heads - 230cc Intake Runners with 72cc Combustion Chamber

Need to find an intake with fuel injector bungs?

Need to know intake manifold suggestions?

This engine might find a procharger in the next two years..

Is there a difference between a round TB and an Oval TB?

What size TB should I get?

What induction system are you planning on? SR, HSR, other. For any of these, with a 427 cubes, go with the 1000CFM TB. Also, I really dont think that there is a power difference between oval or round TBs.

With that many cubes, I'd put a HSR on it.

I dont' really like any of those restrictive intakes.. I am going to go with a single plane intake with FI bungs, I have made up my mind that I am going to go with an elbow and a round TB due to the outlet on the Supercharger in the future being Round.. not restrictions .. Makes sense to me.. I have also decided that I should go with 1300cfm TB of some kind..
