How big of a 4 barrel on a stock 1970 318?

Apparently experiences May differ on this? I've never had that happen more than just maybe having to rekick it down or something and maybe let it high idle for a few seconds but nothing extremely irritating like it stays on for another half hour or something while it's warm.

Could be. Then, it could be the warm climate we have here, too. I just like having more control over it.
