Custom Racing Carbs - Are they worth it
 

Are custom 4150 carbs really worth the money?

Depends on what your buying it for and from what carburetor company.

I use to have a 4150 from BLP that feed my 548 no problem at all. I bought a 4500 and it made no, 0, not a thing, difference. Matter of fact my motor builder was so impressed by it he bought it. I should have kept it. It flowed a good bit more than BLP even advertised it.

You should talk to Chuck Nuytten. My 1050's flow 1220cfm

I got a pro systems carb 4150 made for my combo $705 to my door, very happy with it

i build my own carb's :!: :!:

This is a good story on custom carbs, a buddy (local engine builder and owned his own repair shop) always said I was crazy for buying custom carbs and I told him he was nuts for not. He felt his were as good as any custom would be. One winter I made a deal with him on building my motor I'd send his carb (1150 hp holley) in and get it redone. Following year he bolts it on (never had drivetrain out over winter) picks up .15 with just setting the idle, a jet change and it was .18 faster. I was not shocked but he was. A lot of good carb builders out there, very few great ones, they know their stuff and it shows on the track more often then not.
