Intake manifold choice

**stephen02ws6** · 06-05-2010, 02:31 PM

Hello, i have a cammed 02 WS6 and i want to put an intake manifold on it when i get back from training. I plan on building a 408/427 something stroker later on and twin turbo/supercharging it. i would like to just buy one intake manifold that would work on my motor now and that will hold up to the boost and feed the bigger motor later. I was wondering about the FAST intake but i heard it isnt a good intake for boost since it is a 3 piece design. i was also thinking about the edelbroc intake manifold for half the price. What intake manifold do you guys recomend i get?

I'm running an Edelbrock Proflo XT on my 408 stroker in my 04 goat, and love it...but its tall as hell and have "heard" you need to notch the cowl on the F-bodies to get it to fit...I had to put a small scoop on mine.

I've also seen sevral people running the Vic jr manifold with a 90 degree elbow

I think holley makes an aluminum manifold that is able to be ported and can be modified for forced induction and such. I saw it on thunder racing

Stay away from thunder racing! Most people prefer the fast for bigger than stock cubic inches,I wouldn't think boost would damage a fast intake?interested in hearing other opinions on this.

I've seen pictures of FAST intakes blown apart from FI. I personally would think an aluminum intake would be better for FI applications.

On a naturally aspirated car the FAST would be the better choice since it's plastic and being that aluminum would act as a heat sink.

a aluminum intake is a better choice for FI.fast dose sell burst plates for the 92mm,I don't know about the 102mm.

does anyone know what size inlet comes on the weiand ls6 intake and which throttle body u should probably go with?

any other opinions? i was wondering about the victor jr with the low profile elbow,

Vic Jr is a good choice... Wouldn't do a FAST on an FI car myself...

will i see a gain over the LS6? will it fit under the cowl with the low profile elbow? and would it feed the bigger motor?

I ran a Vic Jr on my 408 (10.60's@127 MPH on motor), mine was ported and port-matched to the heads and I ran an elbow from intakeelbows.com - taller than the Edelbrock low profile, and you have to cut the inside of the hood.

With the forced induction, you won't see a lot of difference because you are pushing the air through it - flow charecteristics are not as important as strength and one piece design (FAST intakes leak where the two sections meet).

The Vic Jr will be a little much for the little motor, but if you want to buy only one, that is the way to go IMO...

Mark "heard" right. You have to notch the cowl remove the wipers and cut the hood. BUT it screams up top! Mine is currently on a stock cammed 346 hoping to find a bigger motor over the winter.

thats for the Proflo XT right? i thought the victor jr with the low profile elbow will fit under the cowl?

ok i thought so. i think with the victor jr, it all depends on the elbow you use.

**stephen02ws6** · 08-12-2010, 10:08 AM

does anyone have experiance with the Victor JR manifold with the ultralow profile elbow? is there going to be a gain over the LS6 i have now? im cammed if that helps.

**LSXZ28** · 08-12-2010, 12:10 PM

If I was in your shoes, with your future goals, I would leave the LS6 that you have on it there and get a Vic Jr when you go to the stroker... spend your money elsewhere, or just save it for the big stuff you want later.
