Can someone tell me when changes were made? I have a Firestone 3.6, 1946 and a Wizard 3.6 without a id tag. they are similar but different. cylinder, block, head. 4 bolt head on firestone, 6 bolt head on wizard-mcc. Checking out parts I find that maybe in 1952 they changed design. Sometimes I see some on ebay and I'm not sure if they are early or late models. I have only ran these motors briefly, not lake tested, but it sounds like the firestone is a little more throaty sounding if you know what I mean. maybe bigger displacement or more power, don't know. any info is always appreciated.
