The June edition of Hot Rod magazine has an article on building a 292. I haven't read it yet but just got the info on old chevy trucks online this morning. I built the 292 I'm running in 1970 3/4 ton 4x4 surburban that I use for hunting and to pull a stock trailer. I learned the hard way about hardened valve seats. Crane High torque RV cam with HEI ignition from a 78 250 gives more than enough torque and now I'm more concerned about MPG. Jim
