I've got one of the JAM Holley kits on my '73 M110. Works great. Their electric choke fits and I can use the stock air cleaner. Linkage all fits.

I've also used an Autolite 2 BBL, a Rochester Quadrajet and a 2 BBL Carter. Solexes are good carbs but usually by the time we get the car they have been abused past the point of recovery.
