454 Mag stroked to 496 w/ProcCharge what carb
 

Winter project trying to get finished buliding 454 stroke to 496 run 8.7:1 comp, Bob Madara cam, 781 heads with work, inconel valves port polish, Question is what size carb. I have been told to go smaller blow thru like 450 cfm I currnetly have 850 but told to much carb and would not work.(Run Lean) My thinking is i need more since pushing air 3.5 boost. M3sc procharger

Any thoughts, sorry if I left any info out,

im thinking around 750 cfm,call quickfuel carbs,they make a great carb and have experiance with blow threw setups.

+1, 750 cfm should be perfect,,if you want a B i t c h i n carberator for your set up and not have to worrie about the temp changes go with a c&s specialties aerosol carberator...they are real responsive too!

Eric,

Did Vrbancic Bros. Racing (AKA The Carb Shop) provide you with that recommendation?

Regards,

Bob

if you deside to go wit hsomeone elses recomendation at leaste have them put auunlar boosters in tghe carb..with the c&s carb theirs vary little restriction unlike a regular booster type carberator..

I'm running 509 w/MSC3 used a 950 from prosystems, was spot on out of the box...patrick is who you need to talk to...Rob
