196x Ford F100, 292

I'm considering buying a 60-something Ford F100 with a 292 cid, 4-speed, and 9" rearend. It's only rusted in 2 spots (bottom corner of the cab) but not all the way through (just starting to rust). The engine uses no oil and has been an every-day driver for about 2 years now.

I have a few questions about the engine, though. First off, what does the combustion chamber look like in these engines? I'm planning on doing some cylinder head mods, but they require good squish to work. Also, what compression do they come with from the factory? The chamber mods will increase the detonation threshold, and if the chamber is shaped right (allowing my mods) will be able to run around 13:1 on 87 octane without pinging. Are the pistons flat-topped? What's the squish clearance? If the chamber has good squish, but the pistons are dished, I'll have to replace pistons to get good compression. How expensive/rare/hard-to-find are pistons (and other parts) for these old engines?

The heads will pretty much make or break my project, and is the single biggest deciding factor in whether or not I buy the pickup. If anyone has any pics of the chamber side of the cylinder head would you please post them up?? That'd be greatly appreciated.

If you're interested in reading about the chamber mods, go to MPG Research and search for Singh Grooves, Edging, Varible PowreLynz, PowreValvz, and Surface Turbulence Valves. Or read my post here.
