Greg, I have the 4.1 in my mildly tuned TR4A. It is hard to compare, but the
acceleration
off the line in better.... But is it significant? If you need every secong
in an autocross, then yes.
It is significant on the road? Maybe yes.
You need the OD to drop highway revs back down to "normal" (actually a couple
of hundred less
than the 3.7 at highway speed)
If you want REAL highway cruzin', then use the 3.7 and add the OD!
The ebay parts seemed a little pricy to me, I'd expect to pay that for the
entire pumpkin, used, ready to
go.
The downside of the 4.1 rear is the speedometer. You need a considerably
different
calibration number and there are hard to find. You might get made a soeedometer
"adapter" which turns 41 rotations into 37 rotations.
