I found this and I am really interested.Has anybody had experience with it?Sounds like a good deal to me.I would like to put a super ram or stealth ram on it.http://www.masperformance.com/460_383.htm

 

Looks OK to me, as far as it goes. Only 2 minor snags: the cam they use (which they don't say what it is) to get that kind of HP figure won't be very friendly to fuel injection; and the E-tec heads have the Vortec intake port configuration, but neither the SuperRam nor the Stealth Ram are available with the intake ports moved to that location. i.e. the ports won't line up and might not even seal a gasket, let alone flow properly.

 

Well they have other options,like this one with vortec heads.Click on the mas performance logo at the top left to see other options.http://www.masperformance.com/420_383.htm

 

Ummm, that one has Vortec heads too. Same deal.

 

The one with the vortec heads is 500 bucks cheaper.

 

Cast iron GM Vortec heads vs. aluminum Edelbrock E-Tec heads. 40HP for $500 ($12.50/HP).

Both require a Vortec-style intake manifold.

 

So, how are you going to put a manifold that doesn't match the ports of Vortec heads, on Vortec heads??

If you are wanting either of those 2 intakes, you can't use Vortec or Vortec-style heads, period. Those motors aren't for you.

If you really want a motor with Vortec heads, then those intakes aren't for you.

One or the other. Can't have both.

 

Miniram III.

Goes with "Vortec".

Or "EFI".

Especially both.

it's designed for the Miniram but it should work with a superram / stealth ram setup as well.

 

Wow........ Lots of misinfo floating around here.............

Mini Ram III will only bolt up to Fast Burn Heads, period........

This is because the Fast Burns are tapped for traditional or vortec bolt pattern intakes.

The Mini Ram III is drilled for traditional bolt pattern, NOT VORTEC.......

Vortec and E-Tec are only tapped for vortec bolt pattern.

Oh and by the way, I have a Superram sitting atop my E-Tec 170s using a SDPC base, and there is supposed to be HSR for Vortec on the way for late this year, according to Doug Flyn at Holley.

 

Guess the originator will have to decide which intake he really wants to use, and get an engine with the appropriate heads.

 

There's more to it than the "bolt pattern".

"Vortec" is GM-speak for "we put the intake ports in a different place". Specifically, about ¼" higher up. They did this, in order for the incoming air to have a straighter shot and less of a bend, right as it gets to the valve. Which means, that if you put a non-Voretc intake on Vortec heads, the ports won't line up; there will be a ¼" step at the top and bottom of the ports; and depending on what gaskets you use and how thick your intake castings are, the intake might not even completely cover the ports at all.

You want a Vortec motor, you gotta have a Vortec intake. Period. Bolts be damned, that's just a tiny inconvenience, compared to the real issue.

 

So far I havent read anywhere in this thread where anyone has talked about crossbreeding a traditional intake to a vortec port.

The SDPC base is designed and cast to match the raised runner vortec port. I own one.

The Ramjet is also cast to match the raised runner vortec port. Gm designed for the Vortec head.

According to Holley the Vortec HSR will also be cast to match the raised runner vortec port. Holley Comments

As far as the Miniram III, TPIS states clearly it is only for the FastBurn head and not Vortec. They talk about running another part number on actuall Vortecs, but state the alternate part number requires a personal conversation so TPIS can rework the ports.

I smell a rat over at TPIS over anything advertised as Vortec or Fastburn. I truelly dont believe they recast the Miniram and are just drilling holes and making claims in order to sell product.

But there most certainly are real deal FI options available to run on Vortec/E-tec heads. That come right out of the box with proper bolt holes and proper runner design.

 

So, what's the smog inspection/testing proceedure in South Lake Tahoe?

 

You only have to smog it when you buy it,then your done.Originally I wanted to keep all the smog but I'm willing to change that.I didn't realize about the heads on those engines so I'll look somewhere else.Merlin7734 gave a good link so I am going to look there.I plan on puting a supercharger on in the next couple of years so mated to the engine in merlins link would be a monster.Thanks for all the feedback.

 

Until they actually do it, it isn't done yet. At this time it doesn't exist.

— The Holley guy

As we like to say at work, "Hope is not a plan", and "hope is not the same as reality". Hope something into one hand and defecate into the other, and see which one fills up faster.

If Holley does in fact re-tool their old Street Ram casting to where it will actually bolt up correctly to the Vortec ports, then the idea of using them together will have some basis in fact. Until they do, it's pie-in-the-sky dreaming and otherwise wishful thinking, and as we all know, you can wish and dream all day long, but the parts still won't go together right.

The reason no one has talked about "crossbreeding" is because in most cases, it's a non-issue. There isn't enough material at the top of a conventional intake port, to allow it to be "crossbred" (ported) to match the different port location of the Vortec heads.

"Vortec"® = intake ports are in a different place

Take your pick: Vortec heads; or a Stealth Ram or SuperRam. One or the other. Those heads, or one of those intakes. You can't have both.

If you put a blower on a motor, the properties of the intake tract lose their significance in proportion to the amount of boost you run. So if you're really planning on blowing the motor, pick the intake system that hooks up the easiest and with the least trouble to a blower, and don't worry so much about whether the runners are raised or not. When the car can't be used to its full potential because you can't keep some gasket or hose or duct from blowing off the car, it doesn't matter very much which intake or heads you have. And, don't make the mistake of thinking you'r egoing to build / buy some mountain motor, and "add" a supercharger "in a couple of years"; optimizing a motor for boost is very dfifferent from optimizing it for N/A. ALOT of things have to change, starting with the compression ratio; which means tearing the motor all the way down to its lowest component parts. Like the Vortec/StealthRam deal, it's either/or, one or the other; not both. If you are really planning on using a supercharger and not just spanking off about it, then build a motor that's right for that, and realize that in the meantime, it's going to be pretty lame. Solidify your plans now, and proceed directly in the direction you are going, because the path you will take is very different, based on that choice. The fork in the road is right now, not at the time you actually decide to order the blower.

 

Ive been curious about that for a while now. For those who dont know, So. Lake Tahoe is right on the border of Cali and Nevada. Since Nevada is less stringent when it comes to smogging, can you register your car in Nevada, or does it have to match the state of your residence (although i dont know who would want to live on the cali side of lake tahoe due to the higher taxes)?

 

And why is it that you are stating you cant run Vortec heads and a Super Ram, again???

Vortec Head + SDPC Base + Superram Plenum/Runners = Combo run by at least 3 people on these boards.

 

You're right; excuse me; you can do that. I was assuming, since the original post made no mention of the intake base but only the plenum & runners, that he was thinking he could use that with no further purchases necessary. What I get for "assuming" I guess.

Of course, then you'd have far more $$$$ tied up in it than alot of other choices that would go faster and be alot easier to deal with in general, so it doesn't make good economic sense, unless you have California visual inspection; but that's different from being unable to use it.

The Stealth Ram non-fit won't be helped by the SDPC base though.

 

before you drop 5 grand on any crate motor you should give Aaron over at www.badasscars.com a ring -- hes over in Sonoma, not far from where I am.
He might be busy, might not. . . you might not want to wait as long as i did for my 355 but i think i got a really strong setup at a good price, and of course hes a blast to work with.
