I'm building an engine and was wondering if you could recommend a suitable sized carb for it. I have a std BG Mighty Demon 750 available to use if suitable.
393ci (3.85 crank and 6' rod),
upper rpm limit 6800-7000rpm,
est power 550-600hp (yet to be run but similar combo makes this much) flat tappet solid cam 264/268 @ .50 duration with 666/678 lift @ .50 compression ratio 11.6:1 single plane manifold weight of car 3500lbs,
3 speed auto with 5000rpm converter (8 inch),
Street & Strip car, but mainly street.
Thanks for your time.
With the combination you have and considering you will drive mostly on the street I would say your Mighty Demon 750 would be perfect. If this was a race only application you could probably pick up a modest gain with a larger carb such as a 850cfm. Hope this helps.
