Rated 5 out of 5 by from Works fine, no adjustment needed. If I had it to do over I would have bought the 500 c.f.m. with a choke. Was under the impression that I could add a choke to the one I bought but cannot. No fault of the 450.

Rated 5 out of 5 by from great carbs though a bit costly, I found the carbs to be great. I just installed two carbs on a tunnel ram and they ran great, even without tuning. the factory did a great job of wet testing the carbs before I got them.

427 side-oiler engine that currently has two 750cfm drag carbs on it (tunnel ram). Runs WAY too rich. Looking to drive on the weekends around town. Will two of these work in place of the 750's for better drivability?

Asked by: JB Fin
The Holley 510-0-9776 carb will bolt in place of Holley 750's.

restoring 64 ford f-100 pickup with 292 four barrel 3 speed will the 450 work?

Asked by: robert S
The CFM size is ok for your Ford F100. You just need to ensure the manifold you are using has the 4150/4160 square bore bolt pattern.

I have an '85 Monte Carlo I'm restoring, would this fit?

Asked by: Mep2ceciltucky
This will work with an adapter if you have the standard Q-Jet intake. This is the adapter -https://www.jegs.com/i/JEGS-Performance-Products/555/15440/10002/-1

Hello: I am looking for a small 4bb carb.  I’ve got a Jeep in-line 6 with an offinhauser 4bbl intake.  I’ve tried a 600 cut, way too big, tried a 500 com and had a hard time tuning it, ran rich or after jet change was a dog.  So I’m looking for smaller.

I want to put a tunnel ram intake on a 1967 327 Chevy 2 bolt main block that I have. Are 2 Holley 450's ok to use. The engine will be mildly built. Will this work ok or should I use a 350 4 bolt main ?

Asked by: John1962
Yes, you can use the Holley 450 carburetors. The 4 bolt main block would be best, but the 2 bolt main can be used for a mild application.
