Q: Carb to suit a mild 318 stroker

I just put a 670 Street Avenger on my 360 and love it. I tried a 600, 725 and 750 prior to this carb. The 670 has the low mid range throttle response of the 600 and the top end of the 725 or 750. Plus I picked up 2 mpg over the 600.

Fo my application the jetting was spot on out of the box and the carb only required setting the idle speed and a slight tweak to the choke (needed it to stay closed a little longer with the open plenum intake).
