Dang thats nice.. Factory 6's must be a rare bird these days. The guy I bought my last 2.0 engine from just before I sold my '73 had just yanked it and put in a 2.7 out of an early Carrera into his 74 special edition (remember the black & gold ones?) He put the proper kit in that enabled the original 4's to put flat 6's in them.

I'll have to dig up some pics and post them somewhere.. Received on Thu Feb 05 2009 - 23:39:03 CST
