Edelbrock Victor JR Intake (Pics and specs) Start out with some pics shall we?
On to some specs for you technical guys
There are a total of 4 runner lengths.
Shortest (inner 4) 4 1/2 inches long
The one with the tapped bung is 6 1/2 inches and so is the one diagnal from it.
The other 2 are 6 inches
The runer height loks to be 2 5/8 inches but this is excluding the injector area. Very eyeballed. The width is 15/16 inch.
The inside of the runners are rough like a stock head casting. I probably wont port it at this time but I might at a later date.

Great pics.
Probably not an intake for someone wanting abundant torque below 4000 rpm. That manifold will really shine at 7000 rpm and above verses a FAST 90mm intake. Just the ticket for bigger motors or hot solid roller setups with stock cubes.

I would imagine it would make good numbers on bigger cubes at higher rpms.

LS1 Victor Jr Specs I've got a couple of answers for you guys:
1) The manifold is just a hair under 5" from the port flanges to the Throttle body pad. I'm pretty sure this is shorter than the GMPP manifold.
2) The basic casting is machined either for a carburetor (PN 2908 or PN 29087) or for EFI (PN 29085) as shown here.
3) Tim Schwanke Tim's Automotive in Minnesota) built an iron block, CNC head, carbureted combination and pulled 650 HP with this manifold, 20 more than the GM.
3) Air speed is related to the cross sectional area of the runner, which is a consistent 2.85 sq inches from runner to runner. The length affects the dynamic tuning rpm.
4) Unfortunately the only comparison I have to the ZO6 manifold is carbureted on the Victor Jr, and of course EFI on the ZO6. The crossover was at 4500 rpm and it gained about 15 hp at the top.
I'm looking forward to you guys flogging this piece and seeing what you get from it.

Chief_engr,
Are you affiliated with Edelbrock at all? If so, glad to have you on the site. I also have another thread I started in the Forced Induction area on this intake.
The actual height of the Edelbrock piece is taller than the GMPP unit according to Kurt @ W2W. Here is his link with a couple pictures. https://ls1tech.com/forums/showthrea...kurt+victor+jr
I think what Cheif_engr is saying though, is even though the Edelbrock unit is taller than the GMPP (From the valley cover to the top of the carb flange) the runners are shorter.
Do you happen to have a copy Tim Schwanke's dyno. I would be interested to see an overlay or even HP#'s in 100 rpm increments as I could then plot my own dots. I would be curious to know if the extra 20hp was bellow the curve as well or just at peak. How about the TQ#'s?
Nice to know the cross section info. When I called Edelbrock while waiting for my intake, the person I talked to could not tell me any info at all.
One thing to think about though is my setup is FI. I'm sure the different runner lengths may play with me a little, but I would assume in a pressurized enviroment, it would be less of an issue.
Spanky, nice to see the GMPP one fit. Most people seem to want to go with a single blade and an elbow to run a filter. When doing a full on race car, I could see using a 4150 style TB with no filter.

i would like to know this also. I was thinking it would be ok for the street and take it off for the track. what about a MAF sensor?
