CorvAircraft> cam question

[Michael Amick]

The # 1605  is also on a cam's box being sold on ebay within 5 hours. 
Item number: 320201344959  It was a perfect circle reverse cam converted 
to reverse rotation by KEP.   "perfect circle part number 229-1605."  I 
wrote the seller he had no more info.  I spoke to the folks @ KEP & they 
looked through their files but could not find the references.  Perfect 
Circle is no longer.  My best guess is that it would be another perfect 
circle brand of cam with a different profile.  You may find info in an 
older reference book though a former dealer/parts house.  If no other 
info is available you can still determine lift & timing without removing 
the heads by using a dial gauge at the valves & Mark Langford's handy 
degree template.  Better still find a dyno like WW's & test for torque 
values at your expected rpm.

> Hello,    This may be an impossible question,  I have an engine here that I bought from an estate, that was supposedly converted for aircraft use.   The cam itself is stamped on the end with 1605 and  252-26    The cam gear says GM 6255610    they both look new   Can anyone tell me anything that might help me figure out what kind of cam it is?   thanks  Gary Richmond
