guys, can I use this for a large bridge port? seller mentions it's a holley single pump carb...humm



RB intake and holley

 

IIRC all the 4150's/ 4160's are single pumpers. BTW thats a 4160. I'd guess that 600cfm is adequate for a BP. What I'd like to know is how do you "jet" a carb from 600 to 460 cfm?????? Thats impossible. Jetting has nothing to do with it. get a model number off the carb if you really want it and cross reference it over at holleys website.

 

but if its a racing beat carb for a stock port 12a then its 460 cfm all their carbs are modded to 460 and thats not enough for a BP

 

IIRC thay have a 600 also that they sell for ported engines.

 

But it's a double pumper, not a single.

 

I hate when people run vacume advance,single feed Holleys on rotaries,

BUT I got a friend who has a 12 sec car,with that set up.


I run a double pumper
