Yup, Ran a Street Demon 750 on a 410 w/Isky 280 Mega but on a 106 LSA (instead of the 108) Saw 14 in/hg in park, idled fine (yes, choppy, but consistent) and had a nice strong consistent chop with about 11 in/hg in gear. Stroker, dual plane intake, EQ Magnum heads with 1.92 intake valve, ports favoring velocity etc. Combo has an impact. Throttle response was outstanding. It’s a great street carb that can be run on the strip to a point. but it’s no Holley when it come to tune ability or ease as mentioned. I’d buy one again if I had a need, they’re nice and certainly not a cheap copy of a Thermoquad. :rolleyes:
