I have an Edelbrock Performer on my '78 K25 GMC. It's a good carburetor except for the fact that the throttle linkage is cheaply made, and in the 2 years I've had it on there, it has worn a flat spot, which causes my throttle to stick every now and then. My brother has a 2-barrel Holley on his '67 International Pickup, and hasn't had any problems. If I had to do it again, I would probably get a Holley.
