I've run the victor and now super victor .Damn our qtr track
shut down so i didn't get to do alot of testing .
But I have a spacer on also when i did run it never got into the 9s as I did with the victor.
I'm wondering if I have to much plenum now.
going make some pass' in 2 weeks then take spacer off .

a Victor 340 on my 408. Ran best with a 1" open spacer and a Wilson 1" 4 hole tapered spacer on top.
Fastest 300

Craig, based on the decription of your cylinder head work, if the same guy
modified your M-1, it's probably pretty decent. There are probably better
intakes for you but, finding one ported correctly might be a chore. I might
post some of my Victor 340 pictures tomorrow.
Hey Vic, It looks like the intake @ heads were ported together, I am still foolin around with intake ideas, some pics of your vic would be good, I am trying to get a feel on intake runner size from the different manifolds available, the engine has been performing above my expectations so no real need for a change @ this point, I cant seem to get past the size of the large port M1 plenum so I never cut the ports to my heads, It would be nice to have a stack of different intakes sittin side by side to measure them up and try to figure this thing out,

Im really surprised that no one has suggested the Eddy Airgap???? For a motor making 500 maybe HP,wouldnt you think an Airgap would be a good choice??
If the OP is looking to make "500+ HP" from a 340 he is going to have to buz the [Edited by Moparts - Family Friendly Site - Keep it clean] out of it, and an air gap ( or any dual plane manifold ) just aint gonna get him there. To start with, he is gonna have to stick with a single plane manifold and give up some low rpm torque.

Ok now for the question of the hour.... Opinions on how a M1 stands up to a victor or sv on a small block over 400 cubes... and thanks again to Kieth and Vic for the good info, I saved it this time 
I posted this a long while back, but will again.
A local friend has a tube chassis cuda. 400 inch smallblock with b1ba heads. it had a victor intake on it. He ran a best of 9.07 with it, and the car was extremely scienced out, very repeatable, well tuned, and had been together a long while.
To improve performance, he decided to try a super victor on it. The car fell off nearly a tenth compared to having the same conditions as when the standard victor was on it. In other words, in the same air, after floggin the super, it was almost a tenth worse.
Knowing this car like i do, and the result of this test being what it was, i gotta believe its going to take a lot of inches to make the super victor shine, if in fact it ever does.
The motor above had a roller, dominator, 13+ compression etc, with a 3.79 crank. He took the super back off and put the much better running regular victor back on it. 
The car ran low 9.20's with the super on it at the time he did the testing, and low/mid teens with the regular victor.
This car is pretty well known by many members on here. It won the Saturday night gamblers race in super pro at Norwalk a few years ago running 9.0's all night.

in my humble opinion the link above is to the item that will make the supervictor intake manifold shine.
on my Commando's there isn't but a slight difference between the SV and the Indy, both have only had a port match done and the Indy was modded to fit the standard LA style head, I think that eather manifold would work well on the Eddy Victor head, I really think the added plenum volume of the Indy is what make's it work a little better,,the SV was approx 2-3 hundreths and about .5 slower but that was several tracks over the season and averaged, didn't do any back to back testing. 
Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.

the diference i think of would be the SV runners aproachangle to the cylinderhead seem to favour a raised runner head,dont realy know how much of a raised runner indy uses to compare with a comando or a comming victor head.
this is just some simple thoughts havent looked at any of these parts in reality just seen pics.

The approach angle of the super vic seems to favor a raised runner head, kinda like the mopar 598, I think the super vic is for the new 16* valve angle Edelbrock head, On my W5s with the ported M1 we tried several type spacers & showed some small gains, It appears the stock M1 plenum is just too small for 414 cubes even with the runners opened up to the max,< I know that many on here have said this for a wile.... but some times I just have to learn it by myself  > Last year we opened up the carb flange to fit a 4500 1050 dom and saw some small gains then we flipped a tapered 2" 4150 to 4500 adapter with a 1000cfm 4150 and picked up 350 rpm and almost 2 10ths, The main difference I think is the increase in plenum volume & the tapered spacer smooths out the 90* entry angle from the carb base plate to the top of the port in the plenum more like a 45*, It seems that my W5s with a tall narrow port is old school to the new cnc shorter wider port which makes the Indy intake a no brain-er but with the added raised runner height on my heads the Super Vic looks very interesting  It looks like the Indy & the victor are close in design with a flatter entry angle and the super vic & the 598 mopar are steeper but the 598 favors a squarer port shape, It kinda sucks that the super vic has not performed as well as the victor so far but it may be the answer for a angle milled or tall raised port head?

The super victor does look nice, but I think when you combine a long 4" stroke with a relatively small port cross section adding runner length (as the SV does over the standardd Vic 340) doesn't add much of anything up top. a shorter "straw" is less restricive at high charge velocities than a longer one of the same diameter. I think on a 340 or 360 the Super vic might pick up mid range torque and power over the Vic on a 500+ hp motor turning over 6800, but on a near standard port size 408-422 the stroke generates the velocity and the valve just wants the least restrictive path to the carb and the Vic 340's short runners seem to do the job well. On a big port motor (with proportional increases to the runner area through porting) the super victor might be a hotter ticket, but to me the combo would have to be past the limits of say a full ported RPM head. Once the cnc development begins with the new 2.15" valves Victor heads...well then it should get interesting.....but then we will be in a similar boat as we've gotten to with the Big blocks; we'll have readily available (I'm not including W5'$ and Indybrock$ here) intake/head combos that can easily generate enough power to go beyond the limits of a standard block. I still think Edelbrock should offer a 2.05"-ish valved 'bolt-on' Victor head option, not everyone is going to want to or choose to re-eyebrow their pistons or swap slugs after they just dropped 4500-7000 into a street stroker No reason those heads couldn't go 300+ without having to go with a larger valve....not everybody will be racing their strokers and on the street the top end advantage of the big valves doesn't typically show up until the upper middle of the port flow window... the ports can keep up just fine through the range most dual purpose motors run 85% of the time.

Vic, Nice 'Gator grain' on the ports  , I did notice on the vics that they could probably use more volume and less turn through the port, I assume that's what you're modding there. also what is the hole bored between the runner pairs in front of the plenum? I did a similar mod to an intake once where I could pump chilled washer fluid through the manifold between rounds through a pair of Tapped AN fittings that flowed below the plenum.  Not legal for super stock though
