Adin,
I recently pulled the Jarrico toploader transmission out of the Berkeley and
sent it for overhaul. It has been installed and run at Bonneville for more
than 10 years. The only issue I found was a layer of crap in the bottom
(should have change the oil more frequently)and a white band of water that
was most likely condensate (same issue as before). All gears, dogs, etc
where in perfect condition with no pitting, cracking or even signs of wear.
This car has been 260+ with no issues.
Many Nascar transmissions are based on the Toploader and spin some pretty
good speeds for a lot longer than we ever run. Most break for strength
reasons. There are several shops that will update a stock ford unit for you
should you feel it is necessary or you can buy a "racing toploader" aka
Jarrico, etc. with all the modification already done. These shops also have
allot of empirical data on how much torque/hp/RPM a unit will take. I think
it is a good transmission and should work well for you.
John

Thanks for the quick update Rich.
The issue was couched as a sustained high rpm run - I might think that
this could happen at any power level. I understand many items (lube,
condition, etc) could contribute.
Now that I think about this . . . all the races the Cobras ran (Lemans
etc) . . . I'd just never heard this before.

Mine has been working OK. But maybe faster cars have trouble. RF
