Yeah that is very similar to the 292/292/108 Mopar; if perhaps a lil smaller.
I've had no trouble getting that down to 800, and with a lil finessing 750, even 700 with conservative timing. You just gotta get the transfer slot set right, and all the air entering the engine has to have fuel in it. So if you're cracking the secondaries for Idle-Air bypass, you better have a 4-corner idle carb. Or some method of getting that secondary air entrained with fuel.The right amount of fuel.
