Hello all,

I'm getting close to engine assembly time. I have a Holley 700 double pump 4150 mechanical secondary carb. Have had it for years. It was great on a hot 350 (jetted way down). Now I'm building a 396. I'm wondering if this is enough carb or if I need to explore something larger. Engine details:

396, 30 over
10 to 1 flat tops
Cam: Howards CL123315-08
----Advertised duration 280/280
-----0.050" duration 227/227
-----Valve lift 0.555" / 0.555"
Intake: Weiand Stealth
Heads: AFR Magnum 265CC Oval Port

Other details: 2500 RPM stall, 355 gears.

Appreciate whatever feedback is thrown out here!
