The gmmp i believe is a little shorter but virtually the same. A friend of mine on here, Chris-M, runs the gmmp intake. I run the victor JR.

They are very simular but the gmpp gives you an extra half inch hood clearence.

I thought I remember reading somewhere that the GMPP is a bit more beefy too compared to the thin casting of the Victor Jr.

Yeah that was in my thread about the victor jr cracking around the o-rings. The victor jr is only thin around the 'outside'. The inside there is plenty room to port.

super victor is superior to all of the above
plenty of metal everywhere, flows better, and taller design. different runner shape and design

Depends on which heads you go with. THe Victor won't fit on the L92's, but will work on all the other LS heads.

BTW, I've got a damn near new Vic. Jr. I'll sell since I went with the GMPP for the L92's I have!

i got the GMPP as edelbrock couldnt get a casting done in 6 months i was waiting, and when they did the manifold wasnt released due to flaws in the casting batch. the GM one seems very well made and fitted perfectly. you need Felpro paper type gaskets with it. mine made 405 bhp@ hubs with a 220/220 cam and msd 6010 box, plus demon 750cfm carb. idles and drives great.

glad i come across this thread.
i have back to back testing of each manifold.
3400 pd
5000 stall
430 gear
235/237 cam
shifting 6900
victor jr was worth .07 in the 1/8 mile. would be a full .10 in the 1/4.
had bo white port it and picked up another .04 with it.
if you are looking for a quality product and driveability wise, the GMPP is where its at. you get some nice hood clearance too.
hard to beat the vic jr for all out et. max HP......
id like to do a test on a super victor, but its not gonna clear my small hood.

Wow Im glad to find out the Victor doesn't fit the L92's, I was going that route! Now I will look for a GMPP thanks guys

SUPER Victor and JR. are only for cathedral port heads
GMPP is the only one who makes L92 rectangle port intake for L92 heads
thus far
