This cover was included with a used 440 block I bought. The block came out of a motor home; is it something specific to motor homes or industrial engines? Thanks for any info. Roger

I will never cut the outside edge of any dampener, never If you do your possibly asking for future troubles with the outer ring fracturing there. I have marked them with a marker or tape of some sort but I will never cut them after seeing pictures of Bob Glidden old Fairmount that explode a marked dampener That failure lead to NHRA mandated SFI spec dampeners the next year after that Last edited by Cab_Burge; 05/09/18 10:02 PM.

There was a orange connector under the hood. It was very limited what it could do. It was supposed to have a probe for checking timing but DRB came out to replace this big machine. I never like the machine it would check the battery first and failed just about every one tested! Last edited by SALEM1912; 05/10/18 02:05 AM.

IIRC, most all manufacturers had them at one time. I do remember after I became a dealer tech that the porters were cleaning the shop one weekend and pressure-washed the old Sun machine while they were at it.
