Bruce, good score. I can tell you it is nice to have spares to work with.
It is also nice to be able to swap and compare stuff, pipe to pipe, tire to tire, etc.
Hold on to your parts until you can test them out, then sell what you don't want. One man's fish is another man's poison.
Time to start putting a motor together. If you are new to this, start with your worst parts and go cheap.
Piston and gasket kit, honed, stock carb, stock air box and filter, NO porting, stock base gasket and headgasket.
Buy a flywheel puller ($12-$25) and a buy or make a leakdown tester. Buy a PASSEL of plugs. At least 4. Get the proper type.
Save the mods and the porting for later, do a stock build first if you need to learn. Then build power on, bit by bit.
If it is stock or nearly so, it is not so likely to blow up, and set-up information is more readily available.
How many posts have we seen:
"I've got a ported and polished bbk stroker with +4 timing, 35mm carb and custom exhaust that has no power. What is wrong?"
Where do you start?
Once the worst motor is together and you are running, you can start hopping it up bit by bit, or rebuilding motor #2, just a bit hotter.
Trust me on this. I have done it both ways!
