Anybody here do any port work on the Edelbrock?

I know that for many years Cad Co. has offered a modified Performer they claim resolves the distribution problems.

Anybody ever see one or know what they do to one?

What cylinders run lean with the Performer?

Thanks

From the posts by LUXLX (about Gordy's Studebaker) and R.E.D. it seems the tapered spacer fixes alot of the problem. Why would that be, though? I have an Edelbrock that Kruzick worked on a long time ago but it didn't do much to even the distibution. Just a minor cleaning and cutting the plenum divider down some. Nothing major.
 
Sean,
Tapered open spacer? What sort of taper? They work better than a straight open spacer?

In any case, maybe the added intake tract length below the carb allows for a better mix before it crashes into the plenum floors?

Sean,

  You wouldn't happen to have any pics that you can post of that modified manifold do you?

Thanks

Link to RED's intake. About halfway down he writes about his combo. .    .http://www.cowboyseven.us/forum/http:// ... 2157 

What LUXLX wrote about was on the old board ,iirc. He said Gordy's car had even distribution with a wedged spacer

I don't have any pics of my intake and it is on the turbo coupe right now. I've welded and hacked on it since then, too. Kruzick just cleaned the last few inches of the port up and lowered the divider plenum a little. My welding was just to allow it to seal to the BD head's raised runners. Never tried it on them though.
 
Qoute from RED caddy, aka Paul

Terry, it's a slick'ed and trick'ed 850. Built for a 560 BBC. The carb change from a worked Q-jet was less impressive than the gain from the added plenum and the leveling wedge, that's how I evened out the cyl to cyl distribution problems I had after the heads were ported. Lot's of time invested in smoothing and matching, from the carb base to the valve pocket. The full flow/bypass fuel setup lets me run lower pressure at the fuel inlet valve, without losing volume. No slosh or float bounce problems. R&D continues on the tall tube tunnel ram... Paul


My bold highlighting. Sean
 
Wonder if you could machine the e-intake at an angle to get the same effect if you didn't need/want the extra height?
 
Hmm thats possible done at the carb base.  I bet that would be difficult though.  Naturally it could be done to a spacer a lot easier.  Some car truck/ tranny combos mount with the front of the engine in the air a lot more so than others.  Mine mounted pretty level.  I think when I put taller back tires on and shorter front tires on that my carb will set relatively level.  When I put the new tires on I will check it to see how close to level the carb sets. 
 
plugs will give you some indication of whats going on but the only ways of truly knowing whats going on is flowbench testing both the manifold and then the manifold thru the head
and EGT temp on the dyno everything else is basically a guess at best.....JW
