I have a set of the Goode Parts roller rockers in my TR-3.  They are very nicely
made pieces.  I originally helped him with the design, as I sent him some stock
ones to work from, so I am not entirely un-biased.

I think those are roller rockers, not roller lifters.  I do agree that 
the GoodParts roller rockers are good stuff.

 Hi
To the best of my knowledge, there is no roller CAM out there for TR3/4/6.
I know there was interest a while back, maybe 15 years ago, but I don't thi=
nk it ever panned out. Note that this was around the time that everyone sta=
rted seeing cam and lifter failures due to issues including the oil composi=
tion.
But I know with TR6, there would be a lot of machine work to get a decent r=
oller lifter in there... if you hear otherwise, we're all ears!

Regards,Bob Lang

I remember looking a few years back and finding a Ford roller tappet that
was >.< *almost* the same size as the tappets for the TR6. ISTR it was just
a touch larger. The problem was they came in pairs that are linked
together, which didn't work in the TR6. Rollers at both ends of the pushrod
would be really nice.

Roller cams and lifters are not a panacea. They have some severe 
geometric limitations that no one seems to talk about. When I have tried 
to create a decent lift curve for our engines, I end up with a convex 
flank that cannot be ground with standard cam grinders. If I flatten the 
flank, I get a mild low lift cam.
