SB victor 340 vs Super Victor? Any back to back?

Any test these 2 on a 400+ inch motor? I think the SV should work better on a 340-370" motor up top, but I'm not convinced it would work better on a 4" stroke motor, unless somebody can prove it to me otherwise.

The old Vic has really short runners and with a HVH or Wilson 2" spacer ( 4 hole tapered for first 1" and then open below) seems to work really well on 408-414's with good heads.

I can't see the longer runners of the SV being a plus On a stroker but they may be a lot bigger cross sectionally, haven't compared them side by side though. The taper from the plenum on the SV looks pretty impressive though.

Any back to back tests and conclusions out there??

I have posted this before but it's been a while
Local area friend and racer has a tube chassis 2400ish pound Cuda. It is ultra well sorted out 400 inch b1ba headed small block. Has different stouter mid 8 sec small block now, but he ran the Brodix heads forever
The car had been a best of I believe 9.03, more typical 9.07-9.13. He used a victor.
Swapped to a super victor, and could barely get it to run real high teens, knocked about a tenth out of it, and the car is/ was real well scienced out, definitely gave the super a chance to work

Thanks, Don

Kind of goes along with my thoughts that longer runners are not really much of an advantage on long stroke/high piston speed motors.

Hoping Vic Bloomer ( who knows the old 340 Vic inside-out) and Brian OU812 at IMM can chime in. Really would like to see a true invective back to back both OOTB, with spacers and modded on a 600 horse 408-416 test mule.

About a year and a half ago,I tested Vic Bloomer's Victor against my Super Victor. His Victor was pretty well worked over compared to mine though.
I will have to get my sheets out and let you know the results again,but off the top of my head they weren't all that much different with the same carb/ spacer combination

Dustin,

Please refresh my memory...

Was the Vic 340 Vic's hand ported one going against an OOTB SV? Also, what did the heads flow on that dyno motor. That was a flat tappet cam IIRC, right?

Yes I believe so, not totally apples to apples but It's the only test I can recall. Keith, who just posted right above you it is his engine and he did the dynoing.

Thanks,

My Vic is a pretty nice piece, probably not as well sciences out as Vic's but I've massaged it pretty well and it's well beyond stock. Been using them for 30+ yrs so I'm comfortable knowing where they need work, as I said the HVH seems to work really well on the Vic.

I was thinking about the SV since it's new to me and it doesn't look like it hurts anything much. The Rocky has plenty of hood clearance and with the Airwolfs the big end should pick up quite a bit up top....headers are still tiny 1 5/8 but I just cut off the 3" collector and welded up a 3 1/2" Schoenfeld slip on combined with a 3 1/2" to 3" flowmaster tapered extender. Too small a collector (almost regardless of primary tube size) will always limit your peak torque RPM and also as a direct result lower your peak HP trajectory (rate of hp gain per 100 rpm)

So I'd like to try an SV, but I don't really have the time to science out any porting gains, so running it OOTB might give me some torque through the middle but looks like it might hurt the top end a tad. My very top end will still be limited by the header tube size, so maxing the torque might help anyway. The combo is light (2950 w/d) but definately aero-challenged on the big end

I didn't test mine back to back but I was not bolting on the SV as is. It had heavy port mismatch as well as flange area being cast heavy.

Seems it is made to whittle on. It was my big top end setup that was tested and didn't want to leave a ton on the table.

As Dave said,definitely made to be whittled on.
The ports as cast were about 318 sized. No way can you just bolt one on and see any gains. I mocked mine up and had Vic do a deep port match and he also did some minor work at the carburetor flange.

My Super Victor wasn't so super out of the box but after some worked it picked up some. I picked it up in a package deal but after playing with it I would never remove a ported victor and replace it with a Super Victor.

All good info, my thanks to everybody!

I'm thinking the only real meaningful "step up" might be a TR with maybe an 1150 Dommy on it

Well somebody bought the Tunnel Ram that's been on the Local Charlotte Crsigslist so I'll be on the lookout for another one.

But I did score a virgin 71 360 block, so now I gotta decide whether to go 4.125" or 4.25" stroke. I'm looking for a fun tow vehicle to tow the Rocky around.

Nobody try tunnel rm on their stroker against a Vic?

Hey Wise Ive not tried it but have been following around 1/2 dozen back to back t ram vs single set ups, it seems the t ram will ave out to a min of 20 ft lbs & 20 hp more some saw 50 hp gains depending on the combo.
