this engine is going into a 65 f100. im trying to figure out if i want to leave or remove the EGR. im leaning on leaving it but not sure how it is plumbed. there is no tube to the exhaustor egr valve, is it all internal in the intake and if i due keep it how do i run the vacuum lines. i removed smog pump and related componets as well. some pics of a stock egr system would be helpfull. any input would be great too.
