backintrouble

i'm having trouble finding any pics of a ported super victor plenum, looking at mine its seems so restrictive so i need a rough guide on how much to remove?
if anyone could help it would be much appreciated

Besides knife edging the runners at the plenum ???

But now need to ask what its going on, lotta intake already.

Cutting back the runner ears any, or reshaping? Was thinking of cutting back the ears at the floor to give a nice radius up to the carb base if that makes sense? 364 ci on pump fuel.
The Jnr looks like it's a lot more open in the plenum, does edelbrock cast in additional material assuming people will port on the Snr?

I'm thinking about going with this intake, is there any reason that you're asking about porting it? Are these known to be restrictive or something?

I don't know? That's what I was asking too. I think I may have gone too big with this manifold for my combo, and will leave it unported. Will probably get a vic Jnr for the dyno session- I need some low down steam in this engine

Let us know how that goes Windmill, I've been contemplating on ditching my Vic Jr. Myself for the super Vic.

DO NOT knife edge the runners.

Sorry to bring back up.. we tighten the converter up from last year, fixed trans, new driveshaft, and put new axels and brakes on rear,, car been more on running back to back et's now..
last week 1.42 60fts and 6.44 at 107 mph with the vic jr
this week changed to super vic went 1.40 60fts and 6.38 at 109
we checked the plug after one run seemed it looked ok but maybe just a tad lean. we never changed jet yet.. its a bummer last couple weeks ran dead on run for money and still cant win, last night dead on 5 and lost... anyways for the money the price is just not worth for 8 hundredths ets,, but we will see if it likes alittle more timing or less and jet change...

Sounds like a good gain to me?
My intake is going to a pro in the next few months along with the heads to go on his bench and any variations between cylinders will be ironed out.
For long duration endurance races I don't wanna risk it.

I tried a super and jr back to back on dyno. Now my heads are rectangle port, but still. The jr has a 2 inch open spacer. I did not jet for the super cause I was sure it wasn't going to help much. We made 1 pull and then put the jr on. Picked up 8 horse over the sr.

it's been years for me but we saw more of a gain to make sure the ports matched up the heads perfectly, on the Dyno we saw so many variables on knife edging the intake, adding material to the runner etc, and change the carb or spacer and it all was for nothing lol This was dealing with class racers who look for the last 100th of a sec.
