Bill - I did a bit of web searching using that casting number. Below are a couple links to discussions on Canadian 6's that refer to that block casting number.

2015 AACA thread on engine identification - refers to casting# 3695408 and a "C" series engine serial number (includes pictures).

2008 "Chevytalk" forum thread - refers to Canadian car/truck engine ID info.

I also found this particular casting number in 3 spots in Greg Wapling's "CANADIAN CHEVROLET GMC/PONTIAC SERIAL NUMBERS AND ENGINE NUMBERS" web page - Listing shows three different vehicles/engines, all Canadian built or Canadian sourced (the Holden in NZ).

Hope this added info may be of some help. smile
