39g lifter fitting to T4

[Massive Type IV]

The new lifters are much nicer than the older ones.....

I have pics of a severe failure of 3 lifters in the same engine, and 2 others in another engine, both had less than 1 hour of run time on them....

The new ones are better for sure, but I think I'll be using my TI converts for a good long while after getting bit by them....

Oliver, thnaks for updating the lifters..
