Does anyone know of a upgraded cam for a hp500efi?
 

Someone posted that thay new of one some time back. Im getting ready to pull the moters out the 390 and I thought what the hell.

Call Tommy at Chief Motors in Florida, He will have a selection of new and used ones that will work great.

You will see a great deal of increased power and punch with a different cam then stock
