Ive got a GMPP single plain intake with an elbow on the car, not carb'd but wondering if a carb plate would work between the elbow and the intake? If so which plate would you guys recommend? A nice 2 stage setup would be great.

Car is a 402, LS3 heads, 4L60, 3.73's, and a small yank. Looking to do an 80E swap soon

Yes a carb plate will work this is one of the best plates out
Speedtech Nitrous 4150 Diffuser 2-Stage Plate System

The Speedtech is probably regarded as the best out there, but it's expensive. I have a Pro Flow plate and love it.

The Speedtech 2 stage diffuser plate is a 4 hole plate from what I remember. Will that interfere with airflow since the intake is a single plane intake and the elbow being wide open above it?

The Zex paremeter plate is a nice low budget plate that works well. I paid $230 for mine with the jets. Your question was why i went with it. I was concerned about airflow with the spray bars and 4 hole setups.

I will be going with a zex or edelbrock just for that reason.

The question I am wordering to you carb style intake guys is what do you do with the map sensor?

what do you mean?

What I mean is where do you get your vacuum source from? Do you just tap into the brake booster hose or do you take vacuum off the throttle body from a vacuum port?

I just looked at the edelbrock T/B and I can't get a good enough picture to see if it has vacuum ports. Does anybody know if the Accufab T/B has vacuum ports?

I run vacuum from the brake booster hose. I have the edelbrock 4150 TB but you won't have a problem with it or the Accufab.

I'd go with NX's gemini twin plate. Its a perimeter style plate and has great distribution. Their dual stage shark plate is sweet too!

I have a Speedtech one stage plate. It will spray up to 500 and was about $600. Hits hard and distributes well according to my plugs

The accufab has a few vacuum ports that you can use or block off, that's what I use.

Inductions Solutions makes an awesome 2 stage plate that will spray as much as you could ever want to. I highly recommend going with them.

Its really not that much more expensive than any other system.But you also get what you pay for.

Well, the speedtech plate is around 600, and my pro-flow plate was 225. To me, that's quite a bit more. My plate hits just fine for what I need.

the speedtech also comes with solenoids and hoses and a bracket I believe for that 600.

The pro-flow is more in price when you include everything else.

**** I think the 2 stage pro-flow is more expensive the Speedtech.

Both make great products though. I also like SJ's plate

Yea if you just bought the plate body it was that much not for a entire kit or you bought it used.

I think I will just put an edelbrock t/b on top of the intake and not use an elbow at all. This way I can use a Speedtech 2 stage diffuser plate with the 4-hole setup
