Boosted slant?
Why? Most of the defective ones have been out of the system for a long time. There was a TSB on them I believe and most got replaced. I have one that had I pressure tested that's excellent. I like them. They are light as a feather.
Because I can't tell the difference between one that was replaced under warranty and one that wasn't just by looking at it, and having worked at a few dealerships, many folks don't get their car serviced there & ignore snail-mail, e-mail, & even messages on the freakin' dashboard that there is a recall/campaign that is safety related.
Some folks just drive, I'm betting there are tons of Tecata airbags ready to frag an unsuspecting passenger right now, even tho' it's been all over the news & a major story for several years.
I like 'em too, but the thought of a pressurized backfire splitting one in two or whatever doesn't appeal to Me, for the 15.5lbs it saves over the iron one I just wouldn't w/o a high-pressure test or just re-welded w/a TIG.
Then there's the carb base, it has a big scallop between the mounting holes on the valve cover side, actually slightly undercutting the BBD gasket shape, I had to epoxy fill&file that in just to put the bigger 2245 Holley on the K6.
Just food for thought, in both the iron & 2pc Al I opened the base to an oval.
