Ok, we're getting somewhere; I have one engine (the slower one) with a 
pulley and a 0.64" (approx) fan shaft; the other (the engine I'm 
thinking of putting in that car) has a harmonic balancer and a 0.74" 
(approx) fan shaft. I'll grovel & get some numbers presently, but I'm 
guessing that points to my having one 145" and one 164" engine? Both 
cars have alternators.
