Hi Guys,

Last year I build my 360ci and they got 446WHP@6800 Pump Gas, using a flat tappet cam 259x264@.050 and .586in 606ex, Eddy Heads ported by myself that flowed 300cfm@.600" Super Victor Intake port matched, Mighty Demon 750 Annular boosters, 12.0:1 comp...

So three weeks ago I bought a Holley HP 950 for metanol cheap, I know that I need change the metering blocks and air bleeds to run with gasoline.

Currently I'm running with a Demon 750 annular booster. This carb is amazing and I never had any problem with them but always I'm trying improve. So I would like to have any opinions about this change...

Do you think that should I change from Demon 750 for a Holley HP 950?

Thanks...

Thanks Mr P Body.

I'm shifting at 7200 right now. Last time that I went to the track my best ET time was 1.79 60' / 4.85 330' / 7.35@99.85mph.

Terrible 60ft, because I was running with a wrong converter and my car don't spinning nothing. Now I'm changing the converter also.

The 950 will work, but requires new boosters and metering blocks going from methanol to R85 or gas.
