Edelbrock 1406 whistling
Hey, Oldmanmopar, the first pic is of a SBC I snagged off the web, before I took pics of my carb for this post. :) It's not my intake or carb.
But, I think you might have hit on the issue about the intake/carb base match. I put the new Mr. Gasket gasket on the car, started it up, and it did the exact same thing. Whistle City.
EXCEPT this time, the leak was on the passenger side, under the choke, and across the front of the base plate. Absolutely NO leakage at the secondary shaft this time. Grrrrrrrr. Looks like it was a coincidence all along.
So tomorrow I'm going to order a high-quality Edelbrock gasket, and I'm thinking one of these:
This is the 1/16" spread-bore adapter plate that adapts spread-bore carbs to Edelbrock manifolds without regular mounting flange...or so the info says. It looks like it might work; it's a helluva lot wider on the sides than the standard setup. Here's what Jegs says:
Putting A Square-Flange Carb On A Dual Pattern Intake? You gotta have this if you're installing a square flange carburetor on an aftermarket intake with dual square bore/spread bore flange. Eliminates vacuum leaks common to this combination.
What do you guys think?
