My '87 Mustang GT came from the factory with roller hydraulic lifters. My
understanding is that the cam grind is significantly different on roller
lifters, so there's some R & D that would need to be done on the cam side
for the TR motors - not many cars to use to repay the R&D costs... Also,
it is my understanding that the roller lifters are usually larger in
diameter than the TR lifters - getting a usable roller in the end of a TR
lifter is not in the cards. The TR motor does have the lifters siamesed so
that having a bar between them is not completely out of the question. But,
I think the lifter bores would need to be machined out more than the block
allows.
Plus, of course, this would not be vintage legal... (But still way kool!)
