G'day, does anyone know if there were different engines fitted to the 78 Indy Pace car model? I have seen a few pix of various examples, some seem to have smooth blue painted rocker covers, others have what looks like alloy wrinkle finish ones - would the latter be just after-market rocker covers or an indication of a totally different engine build? I have heard it said that the latter is an indication of a Mexican built & assembled 350 - appreciate your advice.
Cheers
