do holley carbs have different bolt patterns?(where they mate to the intake manifold) or are different models different patterns.

i plan to adapt my stock intake manifold to accept a holley carb. i think i've seen it done before, but i can't remember where. this will probably involve drilling new holes for the studs and maybe resizing of the manifold ports.

so...is it possible?

also, i notice racing beat uses a 465cfm holley for their 12A stock port setup..so would a chokeless mech secondary 450cfm be adequite? the other alternative is a manual choke edelbrock 500cfm. do edelbrock and holley use the same bolt spacing?

 

Yes they have many different models. But for your purposes a 4150 or 4160 squarebore pattern is what you want. Peejay adapted a holley to his stock intake. izzmus or whatever is his site. A 450 will be a good fit.

went to the holley website trying to see what series this carb is..couldn't find it. any insight?


would a 600cfm be too march carb? i'm thinking it will be...but couldn't i adjust the jets to run properly?


:edit: typed in 4160 as a search at summitracing and found the carb. it states it as being a square bore.

i'm running a 600 on my 12a stock port. it must be jetted down alot, but will work just fine.

Ive used one in the past, not to bad but like my yaw better.

maybe a sterling will change that?

 

will i have to upgrade my fuel pump and add an FPR?

i beleive this carb requires 20GPH @ 6psi

 

I saw the title and thought someone had gotten a Holley to screw a Nikki and we got some sort of hybrid?!!

 

it's sorta like that. finding out if the holley carb wants to hump my stock intake mani.

anyone ever try that FPR from Victoria British? it's very inexpensive...wonder if it's worth a crap.
