I had an E-brock 1406 on a SBC, and my experience tells me that you will be putting primary throttle shaft bushings in it at about 30k miles. Once that is done, it'll be probably good to go, but I also had a ton of boil over from the heat here in California. And the insulator that was supposed to keep the carb cool leaked vacuum so badly that I ended up sealing it with shellac. I'll never buy another E-Brock. YMMV.
