CLASS RACER FORUM - View Single Post - Intake & Carb Recommendation for 481" BBC

Michael Pliska · 07-29-2009, 10:43 AM

I'm running a 481" BBC, with a 0.714" lift, 292°/292° duration cam, Patriot Performance match-ported 320cc heads (2.300/1.880 valves). I'm currently running the stock 850 Holley and Holley Strip Dominator from my old iron-head motor, but figure that I'm under-carbureted for this combination. I've noticed when running against similar speed cars (5.90's in 1/8 mile) I can 60' and 330' quicker, but they start pulling away in the top end, and it will only be worse in the 1/4 mile.

Any recommendations for a cost effective carb & intake to pick up a little HP?

Regards,
