[TR] TR4 Compression Ratio question

[James Henningsen]

Thanks again for all the reponses on the poweder coating of the steel wheels.
I had the ten year old tires taken off today, ready to go to the bead blaster
and found out the rims are TR3 (4 inch width and not 4 1/2).  So if anyone
needs 4 inch rims, I have four good ones. I still can't believe there were
P205/75/15s on those 4 inch rims.

The compression readings on my "new" 62 TR4 are 185, 199, 196, 195.  No
history on the motor except it had a new cam and rocker arm assembly
installed.  Might have been more but no record and no access to prev owner.
This car was off the road for almost four years sitting outside.  Got it
running and it runs well!  How are these numbers compared to fresh engine,
shaved head for modified use etc.  They seem high to me, but my comparison
point is a modified TR6 engine and those run mid 170s for a fresh engine.
Thanks,
Jim Henningsen
