Hey All,
I just ran a compression test on my 8-400 and cannot seem to find the factory specs for my 79 F150 Custom. The Chilton manual says that it does not have an actual spec, but instead to make sure that all of the cylinders are similar to each other. Does anyone know of a max or a min I should be looking for? Thanks for any help.
between 115 and 130 is what i have always gone by. and no more then 10% between the highest number and the lowest number. and remember to have the carb at WOT to do this test
