Rebuilding A 4150 750cfm Carb | How To Rebuild A Holley Carburetor | Holley Carb Secrets |

We are looking at rebuilding my 750cfm e85 4150 carburetor. this carburetor has been installed in my 600hp turbocharged ls swapped dodge w100. Its time to give the carburetor a refresh so rebuilding the 4150 carb is on the to do list. The carb in question is a proform 750 race series carburetor that was designed as an e85 carburetor. the process of rebuilding an e85 carburetor and gasoline carburetor are largely the same so I hope you can use the info shown in this video to help build your own carburetor.

The cheapest way to convert your carburetor to E85 guaranteed. In this video I will be going in detail by detail as to what it takes to convert a regular gasoline 4150 style holley, proform, quickful, AED, etc. To E85. The gas to e85 conversion has been discussed several times but each time it ends with you having to buy more and more parts. I'm here to tell you that that is not necessary and here are the tips that you will need to successfully convert your carb to e85 laid out in this video. The carburetor in this video was provided by @PROFORMParts but this video is my own doing with no input from Proform.

Hello i have this carburetor but wen at full throttle it just bogs

[@NightWrencher]

If its a mechanical secondary, it will tend to bog at wide open if the engine is not set up for it.

So I got a summit 750 race carb looks exactly like this. My question is I plan on doing a torque storm supercharger on my sbc. So I want to make my carb a blow thru. What major changes beside the power valve have you change to make it a blow through carb. I’m am staying on pump gas at the moment.

I had to check out the summit 750 because I had no idea that summit came out with a new carb. It looks similar to the proform at first glance, but the two carbs are definately different. The main difference being that the proform has symetrical radius entries, similar to the Holley HP but the summit one looks like it used to have a choke horn and someone milled it off. I have a whole 3 part series going over all the modifications that I've done to convert my carbs.
