Either the stock Qjet or 76-up Qjet custom tuned for your application. Everyday Performance does a good job and is affordable. If you provide the core and skip the plating, custom tune with bushing work was around $250 for me. It ended up about $100 cheaper than the Street Demon carb. The 625 cfm Street Demon is another option, based off the Carter Thermoquad with many improvements in an all new 3 barrel castings. There is Aerospace polymer or aluminum body options, black ceramic coating, full tuning kits and even a tps available to run an electronic trans.
