Jason:
  As soon as there is a solution to allow me to bolt up an NV-4500
(advance adaptors? or some existing bellhousing?)  I'll switch.
With my 4.10 ratios, a direct high gear puts my engine too high
in RPM going down the freeway.  But I like the 4.10 for when
I have the camper on and around town.  The T-34 has dropped my
RPM to the 2100-2200 range for freeway driving (60 MPH limit).
The 3-4 gap is pretty wide, but not impossible to live with.

I do know where there is a T-36 (I think) in a school bus if someone
is interested.

For those running the Holley pro-jection, does anyone have dual
gas tanks?  Do you need to buy 2 electric fuel pumps in that
situation?  And is the 670 CFM setup that seems so popular
the closed circuit digital unit, or the open loop analog unit?
