Next build motor????

any 318 after 85 will have the boss' for roller cam spider plate. some car motors got rollers as early as 85 but more common after 88. factory roller motors were painted black and non roller painted blue. when i got my 85 van i thought it had a roller motor but the rebuilder painted it black when rebuilt. i can see blue under the chips in the black. but i could just get a roller set up and change it over.
