340 intake and carb combo

That’s the problem. Most of those who claim they are junk claim they can tune them. But they cant.

I would go with the carb that you or someone you know can setup correctly.

For me I do much better with the Holly dual line setups but I have more experience with them. Not so much with the avs or tq style, so I don't run them.

For me it's easier to drain a bowl and swap out jets or valve if needed and easy to adjust float levels but again that's just one guys opinion.

Hope it works out.
