Looking at the alternate list, it would appear that my proposed Y-Blk entry has now moved up to the number 14 spot from 15. The engine build is going forward and the block is expected to go to cryogenic treatment this week as the general checkover, vatting, and rough bore has now taken place. Looks like the final bore will end up between 3.820" and 3.824". Picking out a set of C2 rods this week and prepping them is next on the list at which point pistons will be ordered once the final length of the rods is known.

Ted, I have a set of C2AE rods that I started to prep. They have been magnafluxed and polished. I think I have ARP bolts for them too. Let me know if you can use'em.

Ted, did you see my post under Technical about a possible source for 302-332 rocker stands? Chucks Trucks is a big " junkyard " that specializes in early Ford truck parts.Gary. Thanks for the contact info regarding potential sourcing for the LYB steel stands. I contacted Chuck last week and spoke to him regarding the parts I needed. He knows the whereabouts of two plus sets but has to verify that they are the steel units and not the aluminum pieces. I'm just waiting for him to get back to me at this point. Thanks again.

Ted, I used to have a 337 E-series flathead forum ( I gave it away ) someone there was looking for 337 exhaust manifolds, I refered them to Chucks Trucks, and it took forever and a day for Chuck to respond that time. Dont let too much time slip by before you bug Chuck again if you are on a tight schedule.Gary. Chuck at Chuck's Trucks responded back quite quickly and although He did locate several NOS rocker stands at other locations, they were just priced too high for what I need them for. For the quoted prices, I can build them from steel stock and come out ahead including my time. I'll continue to use the used steel stands as I come across them as they serve the purpose just as well as new ones. Thanks for hooking me up with Chuck just the same though.

Ted: Can you explain to my feeble brain why it makes a difference what the stands are made of? My thinking is that it is the bolts that keep the rocker shafts in proper position regardless of the material of the stands. Thanks. John

I think he said something about the steel ones being taller, or something, so they can be milled to get the rocker arm geometry right.

Ted: Can you explain to my feeble brain why it makes a difference what the stands are made of? My thinking is that it is the bolts that keep the rocker shafts in proper position regardless of the material of the stands. Thanks. JohnThe reasoning for selecting steel or iron over aluminum for the rocker shaft supports has to do with deflection of the rocker shafts at their unsupported ends. Although the Y-Block is not as sensitive to this as the Fe and MEL engines by lieu of being bolted down on each side of the shaft rather than through the shaft itself, it’s still an issue when increasing the valve spring pressures and running these engines into the higher rpm ranges. The steel stands just give an additional amount of rigidity of the rocker shafts at the unsupported ends over the aluminum units and especially if using stock rocker shafts. If just trying to control rocker shaft deflection at the shaft ends, the steel stands are actually only required at the outer positions while the inner positions could potentially still use the aluminum supports. But with expansion rate differences between the aluminum and steel being taken into account, best practice is to stay completely with one material or the other.
.
But as Charlie and Gary both reitterated, I’m partial to the LYB stands as they actually place the rocker shafts up to 0.300” higher on a Y-Block which gives plenty of latitude for adjusting the rocker arm geometry without adding shims to the bottom of stock Y-Block stands. The fact that the LYB stands were also offered in steel for the later model production LYB truck engines is just a bonus.

Ted, were the LYB 302-332 rocker stands cast iron or forged steel ?They'd be cast iron.

Hey Pegleg: There's another big money making project for you. Make Lincoln cast iron stands, with instructions to install them one way on the Lincoln and the other way on the Y Block. You might sell 15-20 sets, and the tooling to cast them and the machining would probably only cost you a couple hundred bucks a set. But the cost of casting them would be really cheap after the tooling is paid for. Look what that would do for your bank account! John
