will be interesting to hear the value.
lots of bare intakes at carlisle for $350-450.00, but they are there year after year.
however, there seems to be an interest in poly power the last couple of years, since there are aluminum intakes and heads available for the 62-67 engines, as well as stroker kits for the same.
i don't know if anything interchanges with the earlier engines.
the only reference to the 2-4 setup i can find is 57 & 58.
please keep us updated to what you find out.
