Stroker intake question and guidance, mainly guidance.
I ran the Air-gap and Victor on my old 410 motor. The Air-gap was only ~1 tenth slower at the track (10.89vs 10.7x) under similar air conditions. I thought the Air-gap had better throttle response...felt a little more torquey (if that's a word)...but since I race more than I drive on the street, I stuck with the Victor. Obviously this is combo dependent, so here is what I was running at that time.
410 stroker, small street roller (248/254 @0.05, ~.575 lift), ported Eddy's, Air-gap with 1" tapered spacer, 750 carb (gasoline), 10.8:1 compression, 8" converter, 727, 4.10 gear, 3200# Barracuda.
I would go with the Air-gap.
