Another vote for Q-jet

I personally like Q-jets. No, I don't own any chevy stuff but an Olds instead. It is not an all-out performance piece, and is quite complicated, but are possibly one of the best street carbs around.

Excellent fuel economy and throttle response from small primaries, but plenty of flow capacity. And they are real cheap as most chevy dudes are too stupid to rebuild them properly! I got the one on my '72 442 for FREE!!! It worked measures better than the 600 Edelbrock that was on the 455 before.

I would urge you to try one on a 460, if I still had one I would. I would like to try a thermoquad but I haven't found one around for my budget (cheap...)

My '78 Fairmont has dual 500 edelbrocks on its 306. Still tuning....

For a high-effort street strip ride I would try a 850 annular Mighty Demon. I don't think much if any difference from a well-tuned holley could be seen, though.

Cheers,
Andy
