I had these rebuilt by Kinsler fuel injection service and ran them in my 95 impala for about 2,xxx miles. I have the flow sheet on all of them. They replaced all the screens and back flow them. My 95 impala went 10.82 with a 150 shot. Heres what each ones flows. Will come with flow sheet and old screens. These are better then new. Heres there web site.
