The pulley/generator on eBay is not the hipo pulley, it is bigger than the =
stock Tiger pulley, but the 4 1/4 hipo.

Many thanks to all of you for sharing your collective wisdom. =C2=A0The exp=
ertise available through all of you here on the List, and the willingness t=
o share it, continues to amaze.
I did find what might be a useful under drive pulley. =C2=A0
https://www.npdlink.com/store/products/mustang_pulley_generator_stamped_fin=
s-100767-431.html
But at $280 it does not make sense to spend that amount of money together w=
ith the $110 for the remanufactured generator, I would have $390 invested i=
n a solution that is inferior to an generator look-alike alternator for abo=
ut the same amount of money. =C2=A0 Plus something tells me that the pulley=
may only be 3.75 inches in diameter, whick would onlu give me about a 12 p=
ercent speed reduction. =C2=A0 That is based on what I see for $900 on ebay=
:
http://www.ebay.com/itm/Ford-Mustang-AC-Cobra-OE-Restored-Fomoco-HIPO-Gener=
ator-Dynamo-/350893612053?hash=3Ditem51b2e39c15&vxp=3Dmtr
Cost aside, I had not factored in the possibility my 347 may need a pusher =
fan for cooling in very hot, slow speed weather/driving conditions. =C2=A0S=
o far in 80 degree weather last year, the griffin radiator, 6 blade fan and=
reduced diameter pulley keep things nicely in the desired 195-205 degree e=
ngine temp range. =C2=A0Have not had a chance to see how things go under mo=
re stressful conditions. =C2=A0 Thanks Mark L for mentioning a cooling aspe=
ct I had not thought of. =C2=A0Hate to have a generator setup that will not=
drive a pusher fan near idle if it turns out I need one.
So for the time being I will just stick with the new generator and stock pu=
lley. =C2=A0 We will see it it lasts through its one year replacement warra=
nty.!
I learned a lot through asking the questions, thanks again everyone for sha=
ring your knowledge.
Best regards, =C2=A0Gene
