I purchased a 1956 292 from an f100, It has been bored .60 over and .10 on the crank. I am building it for my 1956 ford fairlane. I want to get a mild cam for it, will i have to change anything? Also with the rings do I have to gap them or do anything to them since its been bored? Also with the heads, can I use any 292-312 heads? Clearance?

'56 Ford custom: Changing to a little hotter cam, if you intend to wind the engine above about 4500, you'll need a little stiffer valve springs. Not a lot, maybe 90# on the seat and 250# fully open. Then, you should replace the pushrods with tubular ones. The stock solid rods are marginal, even with stock springs. Get .060 oversize rings and you should be fine. Wouldn't hurt to put them in the cylinder, square them up with a piston, and measure the end gap, just to be sure.

Did they change your cam bearings? Might be a good idea since you are getting a new cam. Pay particular attention to the center cam bearing and holes orientation as they feed oil to the heads. While you're at it, get a good roller chain set.
"G" heads and 113 heads are the best with 1.92" intake valves. If the valve seats are shot, put hardened seats in the exahust side for unleaded gas.
Do you have good rocker shafts? Each rocker arm has two oil holes. Are yours clear of dirt and varnish?
You didn't mention rod bearings...
How about moly rings? When you buy rings, they will be "file to fit" if you want them that way.
Normally, the machine shop measures the pistons, and hones the bores to them within .002" max clearance.
Buy a "Best Full Gasket Set". It's less expensive than Fel-Pro, and has neoprene rear seals.

If you aren't comfy building your Y-block, maybe you can have an experienced engine builder do it for you. If you tell us where you live, I'm sure someone here will steer you towards a good engine builder/machine shop. Everything you need is still available.

56 ford custom I know he is busy from time to time but I would recommend Tim (mctim64) from this site. He did my 272 this winter and was great to deal with. Bing

I really want to build it. I just dont understand why i would have "trim" the rings if they came with the .60 over pistons from the machine shop.

It is highly unlikely you would have to "file fit" the rings as supplied. File fit rings have to be ordered special. I would still suggest checking them though, mistakes in packaging do occur.

Yes, the Y-Block book is worthwhile, and the only aftermarket book available. However, it does contain a couple of errors & one or two questionable items. The photo of the timing chain installation is incorrect. And while some might disagree, I'd ignore the stuff about the valley oiling mods. Also get an original manual or copy of one if you can Others on this site may want to comment further..
