I have used the AVS II carbs, very nice on the street. Much improved off the idle response. I also love a well set up Thermoquad.Have you tried the new AVS II carbs from Edelbrock yet? If so, comments?
I have never been all that impressed with previous Edelbrock carburetors on stock configurations nor have I been impressed with the AVS factory carbs either. I always felt the Holley 4160s from the factory on some Chrysler models always had more impressive off the line performance with strong performance from the get go (when they were new and the metering blocks were not all warped as most were after a couple years). Not so with the AVS carburetors - they always felt weak.
Pre 71 I will go AVSII after 71 I try for a good 74 down Thermoquad
biggest issue with Thermoquads is the little wells that leak. and some throttle shafts worn
