Hi, Here are some numbers off of my flywheel. C5AE 6380-E 2617 Can someone confirm they are correct for stock flywheel on 351c? Machine shop guy tells me it can't be stock because the flywheel is from 1965 and might belong to a 390. Wondering if I should really leave it there for him to look at if he is so far off on what it is. Thanks, Sean Mundy
