If you will indulge me, I want to bump this up. I would really really like to hear from anyone who has actually done this conversion. I have to make a decision whether to just go with stock 261 rods and pistons or give the cad 292 combo a try. I already have a race prepped set of 292 rods so it's just pistons and crank grinding but I don't want to go down that path if it does not really work or is not durable.
