For years now the carbs have had some kind of check valve that prevent blow-outs. I've never even looked into how it works, but never had another blow-out.
The only old vehicle I have now is my 69 C10, and it has a very old Edelbrock #1406. It works just fine, but I'm thinking about an AVS2 just because.  |
I used to hafta keep a spare 8.5''Hg Power Valve in my glovebox. I guess they fixed that issue, but it was too late for me.
Sorry about the rabbit hole. I think I was trying to suggest Self Reliance to the OP.
The 1405 is what I think of as an equivalent to my Federal Mogul Carter AFB 9635S. I use the Edelbrock manual. Same as a 1406 but with manual choke. That's on a 350 in my '71 GMC Jimmy. [~600 CFM]
The 292 in the '68 Stepside has a 1404, manual choke but 500 CFM.
