Thanks guys for the info! At least the 885 has larger bores than the 94's and now that I know the bore of a 2GC is I got an 885 core sitting on my shelf so I will measure the bores to satisfy my curiosity. Are the bores on the 885 larger than the 1.300?
I didn't think that 2GC was that large and I remember when I used to have a 64 Pontiac with a 283 and most likely it had a 2CG.
Otherwise I like my 885 and it has served me well. It was pathetically sick last summer with the crank n hope syndrome of either flooding after shutting off the engine hot or having to pour a small shot down the air cleaner and again crank n hope when hot. It had both symptoms even though it started great cold. I ordered a number of kits from Daytona Parts and now it starts very fast hot or cold with a tap on the button!
Since I got a core I can really scrutinize it along with my intakes because I got 3 flathead cores in my shed. My intake on my Mercury is of the cast iron flavor but boring it won't be difficult especially since I know somebody locally who has a small milling machine.
