Calling 340 with Holley 650 dp

Wrt lumpy low vacuum cams and the typical Holley 4777 type carb(std 650DP), I’ve found the idle manners are much better after you convert them to 4 corner idle.

-I just had a little flash back…..
I bought my first Holley carb from Super Shops on Watt Ave in Sacramento Ca in like 1980.
It was a 650DP, #4777 for $115.
