Thanks in advance Jason.

Jason
I too have a TR224 I'll be installing when my heads are completed.
It is a low mileage item with p/n R7972 on the end.
I'd like to know for sure what I got.

Found the specs on the cam grind above

Can you help me out with another it has the letter R (is this
for reverse split) above the last grind number Y8879
Other numbers are 3728R/3110S HR 110.
I'm told it's a Thunder racing spec cam

Thanks in advance

Les
