Chrysler 360 w/ W2 Econo Heads, Headers, 30.over

You don't need a street avenger, that is last carb I would put on any motor with some real cam in it, been there done that w/770 on a 440 10.1 284* .538 lift
3200 converter/4.30 gear.
Thing had a lean idle circuit, kinda like a 600 vac sec.
I would set the blades right to the slot and it would idle for s***, needed drilling of the butterflys.
Instead I had it returned for an 830 chokless, WAY BETTER CARB!

Avengers are for stock to 'mild' engines with milage in mind hence the leaness out of the box.....
