Holley vs. Berry Grant Carbs?

Question

I have used Holly carbs in the past and I have been VERY disapointed in their quality control. I have had to fight and tune them almost as a daily ritual. I know that Berry Grant is almost identical to the Holly's but what I want to know is if they have to be tuned up daily like a Holly?

The reaons I am asking is because I am looking at putting a supercharger on and the kits will only accept Holly or Berry Grant. I don't like that because I am a die hard Eddleborck man. Is Berry Grant better than that POS Holly?

This is from the First Generation Monte Carlo Club web site.
"Ok, this pains me to do, but I have to warn any of you who are looking at buying a carb any time and are searching the forums for information and opinions. I have always been a Holley guy, and recently "upgraded" to a Barry Grant 750 Speed Demon Carb for the benefits of billet metering blocks and base plate, smoother venturi etc. It has actually been great so far. At the same time (within the last year) that I bought mine, a friend of mine also got a new carb for the same reasons. He got a 750 Annular Discharge Mighty Demon. . . ~$500 carb. All was good, carb looked excellent. Well, we've recently been tuning it in using the wideband O2 sensor he got, and he had to take the metering blocks off and he found metal shavings everywhere Holes were mostly plugged up, there were shavings stuck in the metering block gasket where they had just slapped it together not cleaning the surfaces! He was unable to even get one of the main jets out becasue it was screwed into the block with shavings in the threads. He had to vice grip that one out, destroying it in the process. Unbelievable!

After he went through the carb and cleaned it up, it is going well, and tuning up great, but how crappy is that that your new $500 carb is full of metal. I am beside myself, and afraid to open mine up as I haven't had my metering blocks off yet, although it will happen later this week to be safe. We've both decided that the next carb we get will be a Holley. I wish I'd done that from the beginning now as I worry about my Demon."
And
QC, Crap in the carb like you found, Alot of poor performance issues that couldn't be tuned out. These were the main reasons. The real bigge was BG's refuseal to accept warranty claims on obviously defective units!
There were many cases were Summit would send a replacement from stock, return the carb to BG, only to be told it was end user abuse that caused the problem and it would not be warrantied!
OK maybe a few, but what about the ones that Summit simply pulled from the shelf and sent back and were told the same story? We're talking still with the tag on the linkage arm and still with the factory mineral spirits in it?!!!!!!
Here we have a company that is wanting to charge for repairs on never installed carbs?
I wasn't there personally but a guy that I worked closely with at The Paddock worked there before and after his time at Paddock is were I got my info on the Summit/BG deal.

if you set the holley right the first time you dont need to adjust it any more the holley will out perform the grant carb and will give you more power if you are adjusting the holley everyday you may need to have it rebuilt if you have had it for a while that is all i will use on my cars and i dont touch them once they are set you will be best to stay with the holley

Answer 3

I like Holley. They always works for me! Maybe your car is the problem? Or maybe you put the carb on wrong.
