Randy,
That 292 is looking fantastic! Rebuild kits are on ebay for as low as $320...You can also get lifters there to I believe...I know Napa has a rebuild kit for these as well...Call them an see if they have lifters. I'm fully hotrodding mine...more cam, punched out pistons, more compression, bigger valves, lump ports ect....But if ya ever need some info bout them...give me a holler.
Far as the frame and truck....Looking good!
