Hello everyone I have a question for all the experts here, I bought a Offenhoauser 4bbl intake manifold for my 225/6 and I am wondering if a 750 holly would be to big for it naturally aspirated "while I figure out a FI setup" the /6 is a 225 bored 30 over, I was running it on a 1720 holly 1bbl factory carb but now I want to get a little more out of it, so would a 750CFM be to big it is a "list 3310-3" Holley is good condition that a friend gave me, so im not out any money. just wondering.
 
i think yes its waaay to big.but you should try it for ***** and giggles,not saying some highly modified /6 it would work on.but a stock6 ,i would say not
 
my idea disconnect the secondary's. and run it one the front only. cant hurt. you may like it. i put a 318 2bbl on a slant 6 once. it was like adding an other engine. a stock slant 6 does not need a lot of air.
 
ok , BTW what was the hyper pack 4bbl that was used? I have found an adapter for the FI so will use that.
 
It was a Carter AFB #3083.
 
how much CFM? I looked it up on search engines but no luck on CFM
