April issue of Super Chevy Magazine page 15 shows Edelbrock has the new Vortec TPI Base manifold part# 3817.

 

Any other info on the Base? You think they made the corrections to fit most runners? Like the SR..

 

Remember, Edelbrock made the Vortec intake for Scoggin Dickey. I'm sure its the exact same manifold with no changes.

 

I saw the same ad. It say's its compatible with all current OEM and aftermarket equipment, including the stock EGR valve. That presents some interesting possiblities.

 

Might be better buying some aluminum heads that would work with the stock intake, serious money for that intake. Is there a set of heads that will work on the later TPI intake? Anyway Summit has the intake listed;

Yes, stock iron Vortec truck heads work, as well as Edelbrock ETEC 170 and 200 cc heads.

Those are for what this intake is designed.

 

Stock EGR valve doesn't mean stock plumbing. Have to run external EGR, that "kit" cost $70 from SDPC.

Not sure that the Edelbrock/SDPC base flows any better than the stock one (maybe due to slight runner redesign?) but if you ask me, running some good heads that don't require a $400+ base is a much better idea than trying to work around the Vortec issues, especially if emissions are a concern.

Formula for good (emissions) heads for me is fastburn chamber, good flow, exhaust crossover, ability to use stock base (if thats all you want) screw in studs, good valves and springs. If you can get all of that in an aftermarket head, I sure would over vortecs. I ended up with vortecs because I planned to go carbed, after the injection idea entered my head, they became less of a good idea, but I managed to get a "cheap" SDPC base and am running them anyways.

Perhaps you did not see the ad, but the picture I saw places the EGR Valve in the stock location. But thanks for the other information just the same.

 

IIRC, the problem is the heads, they dont have the heat crossover/EGR tube to where it is on the intake so... you need the Corvette setup to plumb from the RH header/exhaust to the back of the intake manifold.

I knew it was just a matter of time before Edelcrock sold that manifold under their own name... probably a licensing deal with SDPC of some sort. And as always with Edelcrock, allow time to test fit the piece of junk they send you so that you can fix or replace it later (my token pick on Edelcrock for the day).

 

Absolutely correct. You can't run stock EGR with Vortecs, it just not possible. There is no heat crossover to draw from. EGR is in stock location, doesn't mean the source for the gas is the same,and its not.

As to fit, amazingly enough for an Edelbrock piece (mine is SDPC but I knew Edelbrock was casting them even then) I don't recall any fitment issues. Oh wait, yes I can. With the engine on the stand, I couldn't run a stock oil pressure sender from the back of the block because the intake covered it. If it was installed BEFORE the intake you could, but then never get the fitting off without pulling the intake. Also had to trim the EGR gasket to fit as there wasn't quite enough clearance for that, but that could be an aftermarket piece of garbage gasket issue.

 

Thats only if the manifold was actually cast and machined right. They dont have a QC department, so you just might get a manifold with one entire side machined wrong enough that its not usable... like on, say, something as common as a Performer RPM manifold.

Keep a set of gaskets handy to verify by eye before you even attempt any sort of trial fitment, and save yourself the headache of even trying to go that far with something that would never work. And definitely dont call them about it, they will just tell you that your factory block isnt machined right.

 

Yes, the EGR valve is in the same location under the plenum, but the EGR gasses come from the port on the passenger side like the Corvettes do.

Hey Kevin! Post more angles of that picture so everyone can see how it works.

 

2 posts in one thread denouncing Eldelbrock?
An axe to grind?

 

I bad mouth their junk every chance I get.

There, now its 3 in one post.

I guess I wouldnt be so upset if they didnt have an attitude problem, didnt lie about their product, and actually made parts that were not only something that you could make fit but lasted more than a minute or two. But, to summarize... I guess I was a bit upset with going through 3 water pumps in less than 3 minutes, and getting a manifold that was nowhere near being close to cast OR machined right. As I said, they have no QC department. Then they try to blame the problem on you or your vehicle, when in fact I had a still bolted together from GM engine, and I took off a water pump with 20k+ miles that I ended up putting back on to run another 40k+ miles. I only took it off to swap to serpentine.

If I ever get an apology besides a form letter saying "Sorry", I might have a better attitude but until then, they get nothing but bad rep from me. And FYI guys if you are reading this, I still have the water pump with the Czech bearing that you insisted was a made in the good ol US of A by Pioneer. Not by a longshot. I might just put it up for display for all to see for themselves... 2 minute water pump. I could rig up some PVC and a garden hose with silicone, JB Weld, and Krazy Glue to last longer than that before it leaked.

Damn it Chris, you better not jinx me...
I got one of their bases extrude honed ready to install in my room.

Think happy thoughts

 

The edlebrock is the same as the S-D manifold that has been around for a couple years and is also known to keep you car solid in the 13's.....

 

BSing aside, I dont think the base would be the reason for that. Arent the TPIS, Accel, and Edelbrock all the same castings?

I know youre talking about the SD/Edelbrock vortec base, but it should still flow comprably as the other 3 standard intake pattern bases.

 

actually from looking at Dons vortec manifold, I think the path had less of a kink than the regular TPI manifold design.

I wouldn't worry about your edelbrock manifold and the extrude hone should equalize any differences between them and the accel base. But if you wanna buy an accel base......

 

Just keep the T56 in solid condition, youngsta, and no one has to get hurt...

I had enough space on mine to run the EGR behind the valve cover so I could pull the cover without messing with the EGR tube.

2.8L F-bodies (and probably many others) use a steel flex pipe for EGR that can probably be used instead of the $70 kit, although from what I've seen, there is no fitting for EGR temp switch in them like there is in the SDPC EGR kit. (which is a Corvette pipe IIRC)

 

about Edelbrock lieing.. yes they do.. they claim "made in the USA"..

i had a water pump that essetially fell apart.. there were parts in the pump, the impeller, that had "Made in Taiwan" on them... as well as where the bearings for the impeller..

nice.. why dont they say "Assembled in USA" not made.

 

Ask "Jerry who" about Edelbrock/Scoggin-Dicky bases. At least S-D, backs the bases they buy from Edelbrock and force Edelbrock to do the right thing. If you buy from Edelbrock and it isn't right, good luck getting it exchanged.
