View attachment 1715171316 I know a lot of guys have had great luck with the victor but my combo liked the M1 (best 11.47 @ 118 mph) over the victor 340 (best 11.68 @ 116 MPH) intake. Combo is 372 CID, 4 speed manual, 4.56 gears, all steel body, full exhaust and interior. The M1 was consistently 2/10 quicker in the 1/4 and 2 MPH faster. I never ran it unmodified as I used moroso A/B epoxy on the carb flange to better match my Holley carb but I’m not sure how much it helped. I just made the switch to a modified Weiand action plus and will take it to the track in the near future to see how it does compared to the single planes on my combo.
