Hi Everyone Does anyone out there have a 750vac holley 4010 carb on there Vette I'm looking at buying one to replace the 600vac any advice on them would be great !!! Cheers Mick

If its a small block then you will be way over jetted. You will have to do some modifications. I have put a few on 350's and had some work to do to get them to run smooth. Also with that size on the small block you are better to run mech. seconds than vac. due to having to change things in that area also. Just my opinion from what I've worked on.

Thanks Vetteman thats the best way to learn from others who have been there and do it Thanks for the time to answer!cheers Mick

Holley no longer makes this carb so I would steer clear of it just because parts may be hard to find should you need to fix or tune anything.

Thanks thats what i needed to know i seen them on Ebay cheap now i know why Thanks for your advice Cheers Mick

I would stear clear of this carb as well. I see alot of them at swap meets cheap. I am currently running a Holley 750 vac. 3310, (different design). This is a popular and reliable carb. These are not that expense new. Another popular carb that is similar is the Demon Carbs by Barry Grant. These carbs are not direct bolt-ons to the stock Chevy Q-jet intake. Didn't notice if you had an after market intake...
