Re: Switch from Qjet to Holley
I would keep the q-jet maybe send it to a carb shop for tuning. I have tried a 750 Holley on my 327 and I couldn't get it tuned properly. I now have a 600 Edelbrock which works much better. I'm tempted to put the old q-jet back on, but it now has a square mounting intake. I would have to use an adapter etc. The problem as I see it is the 750 Holley's have to big of primaries. The 600 is better, but the old Q-jet has even smaller primaries, which will give you better street manners. A 327 doesn't need a 750.
