If using a 292, you might be able to use the original bellhousing and rear motor mounts with the 292 with one of these plates. http://www.transmissionadapters.com/Chev%20235%20six%20cylinder%20to%20Chev%20V8%20Style.htm

That would allow you to bolt the brake and clutch pedals up like original and let you use all of your original clutch linkages. this would locate your 292 a little bit forward, but the bellhousing would be in the exact same position the factory put it. You would have to fabricate your own front or side mounts for the 292.

I'm not 100% certain this will work. The 292 flywheel may have to be spaced back, and there may be problems with the starter fitting. A 1955-1959 chevy or gmc 12 volt stomp starter may bolt up and allow you to continue using the stomp start.

I am guessing here, as I have never done the swap.
