I am curious if there is an adapter plate that may be used to mount a Holly 600cfm onto the stock 12A manifold????

Just curious if someone knows of an adapter plate. Yes i know RB sells kits etc.... But I am just after a plate. Any suggestions, warnings, or flames?

I know the adapter you are talking about. It was really popular with the Ricans in NY. If you have Rican friends check with them.

I will follow up with a friend and I'll let you know.

I havent seen those plates in a few years. I did see a guy that took a Holley base, cut the stock Nikki base and welded and ported the Holley plate on the stock manifold

Yeah, my Rican buddies all wont let go of the ones they have I may have to get a pattern for it and go to town with my plasma cutter and drill press ...

ugh, fabrication is nice but i was hoping for some instant gratification

I made one fit long ago, here's the post https://www.rx7club.com/1st-generation-specific-1979-1985-18/holley-stock-12a-manifold-530325/
Wasn't all that tough, just a common holley to small afb adaptor off the shelf, a drill press, a grinder, some ultra blue silicone, some JB Weld and presto chango...

Considering the fact I had all this sitting in the garage as junk, it was an interesting experiment that worked.

I uhm, am pondering using an Ellison EFS 10 or EFS 5 flat slide carb.

It has adjustable venturi's so you can enrich or lean the mixture out on the fly....

These carbs are for aviation use but i cant seem to find any reason they wont work on the street, i may try it since a buddy has an Ellison EFS 10 i can borrow for a bit. I will just need to fab it up to the 12A intake. Granted, nobody wants to constantly adjust A/F ratio... But the idea of being able to adjust the A/F ratio from inside the car while at a stoplight or even while driving is just irresistable to me...

If i can get my hands on this carb and get it fabbed up, I will see about putting it through some violent turns and slaloms to see what happens...

But for now, I will still seek out the adapter plate for a holly. Great link by the way on the fab job for holly.

Thanks!
