I have a little steel rod info for ya. I to am building a turbo 292 so I've been looking for some aftermarket steel rods. Pauter give me a quote of $1290.00 a set with 5-6 weeks delivery. Carrillo gave me a quote of $378.00 per rod. Holy crap are they proud of those? I was also quoted $780.00 for a set of GRP aluminum. I'm not sure I can't get away with some reconditioned stockers but according to Leo's book their pretty weak. Good luck with your project.
