O.K. ,; It's *FRIDAY* and my brother is coming over so I plan to yank the pre - smog cylinder head off my '66 292 engine and send it out for major rebuilding , it'll go back on my '60 C/10's ailing 250 , I'l prolly slap in a set of " gapless " piston rings and rod bearing shells too if needed (this is supposed to be a low mileage rebuilt bottom end) , that'll stop the incessant oil burning and spark plug fouling . At the same time , I'll replace the old exhaust manifold for one I found with a working heat risor and fix the Choke Stove too , that's been a bee in my bonnet since I bought this truck last year ~ I like to have everything working .
