VORTEC MANIFOLD BASE

I'm in the process of getting quotes for tooling on a new manifold base that would allow the use of later model Vortec V6 Heads on SY/TY engines. We'd do some performance engineering this time around and possibly develop a new upper plenum for Air to Air setups. Tooling for a base would probably run in the neighborhood of $30,000. My goal would be to break even on the project! NOT LOSE MONEY.

FYI: BrianGreen said screw that and just hack a RAMJET 350 Manifold and weld it together!

Since the FORUM is where things happen I have decided to put it to a vote! Anyone interested?

thats a lot of $. I bet people would be willing to spend 600-750 tops for this. That means you'd need to get 40-50 participants. And there is no way that many people will fork over the $.

$30k sounds a tad high. Did you farm out this idea to other vendors, or just go to a local shop/friend? I was expecting more like $10k to be able to cast these kinds of manifolds. I too was toying with this idea, and find it interesting that there is another person doing the same.

There is a guy on s-seriesforum.com that has hacked togethor a Ramjet intake for his 4.3. I believe that his truck is a '99 so he has teh new heads. From what I understand it was a pretty major undertaking. I'll see if I can dig up the post and some pics.

I have been considering doing this for awhile now. Problem is the expense of tooling up for a casting. A sheetmetal version would be cheaper IMO.

I want to retain the look of the stocker otherwise I would use a regular manifold setup for MPI.

I think if you were going to tool up for a new upper/lower to fit the Vortecs the best option would be to use composites. It would be lighter and would not be subject to heat soak allowing lower IAT's

It sounds HIGH to me as well. I'll update this once the quotes are in. My ultimate GOAL with this is to bring a whole new generation of S Trucks into turbo power. With the very limited production #'s of the SY/TY program parts are expensive and scarce. We have aftermarket headers so the exhaust is covered, A/A intercoolers, why NOT a good intake manifold?

I like the RAMJET approach actually. Green pooh poohed my desire for messing with the stock intake setup in favor of this swap. I want to see the ramjet work myself.

As we speak the BRAPHOON is being shredded of its turbo drivetrain and I'm installing everything into a 1995 L35 4x4 S10. This time around we're adding a PT52 and a PROTORQUE converter in the trans. I'll chassis dyno her with the 4WD T/C and swap the 4472 AWD over after the DFI's tuned in. I'll make sure I take pictures

For the 94 up "pipe dreamer crowd" the later PCM's are a hassle especially the 94/95 VCM crapola unit that also controls the Antilock brakes. GENIOUS HUH? Since I'm a partner in a Chicago based company called Digital Horsepower, Inc. and we specialize in OBD2 PCM's. The 98up trucks could become a reality with the DHP boxes.

We all KNOW that SY/TY's are a blast to drive. I like the later model sleepers cause I can drive em in the snow and park em at the mall and they stay MINE! :D No one knows there's a 10K drivetrain making 550hp under the hood!

didn't think GM went into production with the ramjet intakes. i figured finding one of them would be just as much of a pain as finding an exta syty intake.
