The 292 is original to the truck so we are keeping it and we're trying to make it as light as possible.

OK, sounds cool. Good luck!

Battery relocation and an aluminum radiator would probably save you more up-front weight than moving the engine back a couple inches. Also an aluminum water pump, if available, and a manual steering box.
All the above are located well forward of the engine center line; some ahead of the axle line.

However, it sounds like your minds are made up on a set-back 292. I hope it works out for you.

Saw this post late. For anyone trying to remove pushrods with engine in place. There is not enough clearance for pushrod removal. '66 shown, but '67-'72 probably has the same issue. Here is what GM recommended.

The Book doesn't say what to do with all the holes after you've buttoned the engine back up.
