I have a 350 and turbo 400 setup in my 87. Its got a holley 600 and an hei distributor. It runs great until you hit 2500 rpms in third gear. Any other gear it fine but in third it falls on its face and won't do anything until you let off the throttle completely and it picks itself back up. I've replaced the distributor, fuel pump, and fuel filter. The only other thing is that it has a valvetrain tick to it. I havent got a chance to check it out with a vacuum gauge but other than that I'm stumped.
