Joe,
I am about where a Stage 2 head would be for head flow, cam is not a drag racing cam, 242/246@.050, .595 110 LSA on 105
What we did on my RPM was a port match, and went about 2 inches into the port.
Then we did some mild plenum work, I dont have a finished picture, but here is the first step. We cut the plenum divider down slightly (1/2 inch) but left vertical wings and a blunt edge on the divider in it at Edelbrock's back shop recommendation.
I also matched the 1 inch phenolic spacer to it, and what wasnt finished in this picture is we rolled the edge of roof a bit, especially the rood of the top plane with a cartridge roll to make a more gradual turn. Basically, in the pic below,where you see alum under the spacer there we dressed it and rolled it back to a nice rounded edge, not much taken off
With and without the spacer doesnt change any part throttle drivability but with the matched spacer it gains a ton of butt-dyno up top.
I also have a matching spacer with a sheetmetal plenum divider I made to block everything I cut out so I could compare afterwards, again, no noticeable change down low either way, but you can feel it loses on top with the full divider to the carb
The question is, do you think an as cast Victor with a clean up would be worse in the 1800-2500 rpm range?
Seems like a silly range in this crowd, but with 3.70's and a .64 OD, I am in 5th gear I have a 2.36 final drive, I plan to go 4.11s soon, but it will still only be a 2.63 in 5th, so it spends some time idling around (and I dont want to downshift LOL)
Here is a pic of the intake about 1/2 way through, what is your opinion on how the Victor would behave in town, not WOT
