Carb Intakes? Ok so I wanna run a Victor Jr. but as far as I can tell, they all come with the injector bosses machined in em. The Edelbrock web site didnt have any P/N's for a manifold without the bosses machined, neither does Summit or Jegs. But, the pitures (I know, sometimes the product doesnt exactly match the pic) show the manifolds with the bosses machined. Also, the Edelbrock web site has all the carb style manifolds listed as EFI manifolds. Do I hafta buy the more expensive GMPP manifold to get one with the bosses pluged, or what?

Ahh, ok. Thanks. I went and looked at the Edelbrock website again. All I had to do was click a different tab labled "LS1" I woulda thought all the LS1 tabs would take you to the same place, but they dont. Ohwell.
New question tho. Both the Victor Jr. and Super Victor carb manifolds are P/N 28097, so for anyone who has ordered one, how do you distinguish between the two when you order?

Ya they do, but it wouldnt be a good match for my MS3 and Patriot stage II's lol. Ya I was lookin through the stikies and saw that there is a difference between the two controllers. Ill be using the 6010 box for sure.

Its more about the power range you want to use. Pretty much any of the ms cams dont even think about power til 3-3.5k. So a manifold that works Idle to 5500 wont be a good choice no matter how much ci you run. I personally run the gmpp on all my carbed ls motors. I figure they designed the motor so they are most qualified to design an intake for it. JMHO

Thats some good reasoning there. I never really saw it that way before. Thanks for the input!

I don't know that I have seen a head to head comparison of the Edlebrock and the GMPP manifolds. GM is putting a lot more effort into their stuff than they did in the past. I would be supprised if there was a significant difference between the two products.
As for dual plane, I think a lot of people make a mistake trying to take tried and true rules from the first gen world into the gen 3&4 world. Like carbs. I have seen a number of people complain that greater than 650 CFM is too much carb for a 350 CI motor. But it is not displacement that determines carb size, it is airflow.
LS motors flow so much more air than even a built up first gen SBC that it seems a shame to use anything other than an open plenum design. Even with the open plenum they are still making more low end torque than most first gens, so one has to question the need for a dual plane.
Age old argument I guess.

ok, now you guys have me thinking.....I'm putting a carb on a STOCK 5.3l. Based on my old school thought process, a dual plane was my choice due to its better all around performance.
I'm wanting this motor to have a very streetable attitude, for a daily driver yet i also want to have power...for the stock motor. Which one, dual plane or single plane for a stock set up? Thanks!
