Quality control??

Don't feel too bad. This is my brand new Air Gap intake. After it was powder coated and gasket matched, I set the carb on and noticed the throttle wouldn't open at all. After closer inspection, it was evident that the carb mount holes were off center from the plenum. I set my 4 hole spacer on and saw the same offset. I traced the spacer hole pattern to the intake and did a little carbide bit work. It's fine now. But I wish I'd caught it sooner, before powder coating, so I could have returned it to Summit.

Wow, that's a sad deal. This is a "heads up" for everyone.

I'd be curious on the Summit and Edelbrock reaction to such a blatant defect. Have you inquired or responded with a product review of the issue with them?

Definitely a heads up for sure. I have not contacted them or reviewed the purchase. Might be too late now. Been about 4 months ago. I'll check on it. Figured it's too late for them to do anything meaningful about it, since they're not gonna cover powdercoating cost.

Btw. The same shift caused the runners to be off slightly at the head. Not much, but noticeable. Blended all runners to match gaskets.

20+ years ago a friend went down with another guy to Scott Shafiroffs place in LI to watch them dyno test a new all aluminum, dry sumped, big chief headed, sheet metal TR equipped 632 BBC.
As soon as the engine started, a stream of coolant started oozing out of the brand new, cnc ported, titanium valve filled cylinder head.
Engine was shut down……. And apparently there was no panic on the scene.
Out came the drill & tap, and pipe plug with sealer.
Within 10 minutes the engine was back up and running.
They said “we see stuff like that all the time”.

The real question is, when is the “dyno test thread” planned to make it onto the board?

My first thought would have been "how do we know there's not a constant stream of coolant going into the valley of the engine?" A little pressure or vacuum testing can go a long way before assembling that level of stuff. Seems like that would even become S.O.P. after the first time... Scares me to death!

Not much has changed I had a ho;;et street dominator that had many vacuum leaks beause of porous casting , that was in 1975
