Edelbrock RPM Airgap Bolt Hole

Not sure where to post this question, if this isn't the spot. My apologies up front.

I was wondering if anyone else has purchased one of the Edelbrock 7576 SB LA intake manifolds recently and found that the 3rd bolt hole from the front passengers side has either been recess ground with a Die grinder or recess milled?


I ordered one of these from Summit a few weeks ago and noticed the Die grinder looking recess job on the above mentioned bolt hole. Called Summit and they shipped me out another manifold on the spot and gave me a shipping paid RA number for the first manifold. Great service on their part there.

The plot thickens. The next intake came in in a few days from Summit. Yep you guessed it. Same exact bole hole was recessed ground down about 0.057" deep and 0.759" diameter using possibly a Die grinder. We were 2 for 2. I called Summit and spoke to a different person. This guy I think ran the warehouse down in Arlington Tx. He said he thought he had a few extras out on the shelf. I asked him if he wouldn't mind having someone check one for me to see if the same bolt hole was ground down prior to shipping to me. I got a call back in the next day or two and was told that I would have to wait to get a new replacement manifold straight from Edelbrock. The replacement manifold ship date from Edelbrock was pushed back twice but finally came in today, with that same 3rd bolt hole recessed. Now this time it was actually machined down with what I suspect may be a mill as the recess was at least smooth, flat and uniform on the bottom.

Edelbrock had asked me to ship one of the first manifolds to them, at my expense though and I had already paid for shipping once from Summit. So since Summits RA was postage paid I just sent it back to them thinking they would complain to Edelbrock about the Quality Control??? Spoke to Edelbrock Technical Support again earlier today and told them what was still happening and was told that I should have paid the shipping to them so they could see the manifold and the problem could have been addressed as they were unaware of any issues. Technically that wasn't true because I had been in contact with there main Warranty Manager on the first two intakes and actually sent him photos of the first two manifolds as shown in attached photo below, so they were aware of the issue. Also gave the manager the LOT Date numbers on the first two (07/23/22) and gave the tech today the number on this one. Not decided if going to keep it or just send it back and go with a Wiend Stealth. I know it's a cosmetic thing but shoot for almost $500.00 it should be right.
