I am running an L28 in my 80zx. I have triple webers on an E88 head, big valves, header, 280 cam with 460 lift, 2 1/4" exhaust. Does anybody have an estimate of what kinda power I have compared to stock?

 

Take it to the drag strip and make a couple of passes. Only real way to tell how much HP you have and provide a number that can be truly compared to other cars. Not only are you going to have a blast (guaranteed you will be hooked) but you will get a feel for what state of tune your car is in.

Big difference between what you should have on paper and what you really have.
