Compression test, can you do it before break in????

[79 bronco]

I just got done doing a leakage test on the blaster's new CT 252 bigbore stroker and its looks good, and i was thinking about doing a compression test before i do the break in procedure, BUT i was told not to because the compression test will look bad and just frighten me because you have to do the break in procedure first to SEAT the RINGS to get a good reading.... IS THIS TRUE????


LOOK CT break in procedureVVVVVVVVVVVVVVVVVVVVVVVVVVVVVV

I would do it just to see the differnce in the rings seated and unseated

The number before a proper break-in doesn't mean anything but you can do one.

My compression came up about 10 PSI after break-in.

I did one before my breakin came back at 118 I was terrified and tore it all down and checked... everything was fine so I went through break in and it went up to 160 I was very happy then... the compression will rise slightly still after breakin cause the rings still are Not fully seated. But it wont jump more than a couple Psi after

If done correctly, the compression should come up 8-10lbs after the break in.
