Lon, yes i think the gearbox is as you say! i know guy who has similar one in 55 f100, but has the shift levers on top of cast g,box lid and has flange on output end. Yes you have described the 292/312 situation here spot on,  regards bill.

That tranny appears to be full synchro. Didn't know they were ever used behind Y-Blocks. Just found out recently that New Process full synchro 4speeds were an option on 64 trucks.

If it's any comfort I think all the hype over C1AE and C2AE blocks is just that. I'll take an EDB or B9AE any day. I've seen 272's bored to 292 that were thicker than a standard bore 292 C2AE.

I.M.O.: Take any old Y-Block and drill/taps the mains to accept ARP bolts or studs, line hone it and don't worry about it. The only blocks I avoid are EBU for obvious reasons and ECZ-C, can't install the cam in most of them. I have found that if you take the time to really clean the cam bearing bores it helps a lot.

 Your 272 main caps are stouter than any of ours anyway.

All Y-Blocks for sale over here are 312's and they all came out of T-Birds.

Thanks john for your kind comments, i agee with it all. We all thank you for carrying on the future of these engines with your new modern performance parts, as there are very few places left to buy just the simple things for them. best regards bill.

I had a C2AE 292 truck bored too a 3.80 312 size and had the heavy webbs I bought from gord in Canada. But after checking wall thickness from sonic testing there was no way the engine could be bored anymore with safty in mind because of the thinner walls this block had. I've had MUCH BETTER LUCK with 312 blocks being able to bore one hundred thousands + because of there thicker walls. It pays to sonic check a block when boring for performance. The C2AE block bored too 3.80 only had .070s left in one of the cylinders which is ok but I wouldn't recommend going anyfurther than that.

John: those Aussi main caps are stouter, because they were likely made in Canada, eh!
