Another Super Victor?
I've never ran a Super Victor but ran a Victor on my pump gas 408 and was very happy with it. The cam was a 260/264 @ .050' flat solid and with 4.10 gears it pulled from everywhere.
When I dynoed my 434 it made 13 more hp with a HVH Super Sucker, the guys at the shop told me they had sold a bunch of them after they were tried on the dyno.
