Edelbrock Clevor

I got this back from Dennis Carrico of DSC Motorsports:

"Hi Dennis. No flow sheets. I do check as I'm in the Heads working, but only keep sheets for the street/strip and max port efforts. There was a big write up in one of the mags on a Clevor engine recently. Your's would compare favorably, I'm sure, to the Ed Heads that were used in the build for that engine.

The AFD and CHI Heads are not street performance items like the ED heads are. They are baseline + race Cylinder Heads as delivered, and have more port and Valve area, AND flow potential than the ED's do.
The ED's you have can be made to do MUCH more than they are right now in your current use. Email me in regards to that.
If you need more to begin with, I offer the BT 3.6" and 4.3" Cleveland Heads as an alternative to the CHI and AFD Heads. The BT's are superior in EVERY way to those heads and will crush them as far as power potential and output."

Let me know if this settles the arguement. Thanks, dennis

If I recall correctly the BT's (Blue Thunder?) heads are considered race heads. I believe that is why they were not seen at the Engine Masters competition.

That would not be an apples to apples comparison as the CHI's are considered a street head, as are the Edelbrock's.

So Dennis is your engine builder saying that even after porting the Edelbrocks don't make the same powers as the CHI's?

When you quote him he says the CHI's have more port and valve area and flow potential than the Edelbrock product.

Would that not seem to indicate that they SHOULD be making more power than the Edelbrock product?

That's what he's saying. The eddies are made to be milder street heads. If you read the post he says that the CHI's have more valve and port area which indicate more flow potential. Comparing the CHI to the BT is like comparing the Edelbrocks to the CHI, all different designs with different purposes in mind. I never claimed that the Edelbrock made as much or more HP than the CHI's, just that they were a cheaper alternative so you can stop defending your choice. No one has put the HCI's down, they are great heads no doubt. There are many factors to the choices we make for our car (performance, price budget, asthetics etc.) That's what makes this car great, personalization.

Just returned from a vacation in Hawaii (Hilo/Wikiki) and saw this thread. I finally have 6958 running good after a complete rebuild having solved the thermostat/msd problem, may need to jet down the 770 holley a bit. I've got approx 10 miles on my it now. It has ED heads / Airgap manifold. I had a Torqer and 4V stock heads. So far I am happy with the drive ability and performance, the first time I jumped on it a bit the clutch slipped from the power. I adjusted it (from the setting the old motor had) and wow what a ride. I have a crane roller cam with roller rockers and a jomar stud girdle. I would have liked a bit more lift cam but the .600 max limited it. I wanted to keep it close to stock but have a bit more and still keep it dependable and it seems to be ok so far, even after getting things a bit hot when the thermostat stuck closed. I've been through the days of high lift cams and always tinkering with things and just wanted something mild with adjustable rockers and the ED heads so far have fit the bill. Just my 2 cents worth

Stock Edelbrock flow sheets.

Anyone have flow numbers for the Blue Thunders?

What is the part number for the Edelbrock Cleveland heads?

The heads for the cleveland are the Performer RPM #61629. The Performer RPM Clevor heads for the Windsor are #61699.
