I've always had really good results with AED carbs, and I have used the 650 on a 327 which worked very well right out of the box. Here's one with a choke, but they also have versions with the air horn removed if you prefer.
I think I've made my decision to go with the qft 650 now I'm running a winters intake anything in particular I might need to hook this thing up other than a single to a dual inlet?
My Pontiac M/T crossram does not have enopugh meat for the Holley bolt pattern so to use the 715s I have(ran on the '09 back in the '70s) I'll have to use an adapter.
