So is that the reason have a '47 with a steel head and a older '47 with an aluminum head? Or was the replacement head always aluminum? I always wondered that.
The ID plate looks respectable for it. Looking good as always Matt
Isn't there a difference on some of the parts for the older style 8s vs the newer ones? I can't remember if he has the newer one or not on his saw.
Model N's could of had an aluminum or iron head even on the earlier ones. It didn't have anything to do with year. Briggs used both depending on application. I have a 46 with an aluminum head, and I have a 52 with the iron head.
As far as differences between the round, and square 8's go, the internals are the same. The magplate, and shroud are different, and the head is different, although the chamber, and bolt pattern are the same. I recentley put a early round top mag plate, and shroud on a square 8, and everything bolted up, and the engine ran fine. Now everything changed when the 8B started, as it was an aluminum engine. Hope this helped.
