Panic, Agree on corrosion. I'm mint in that dept. Started driving Chev farm trucks as kid in '47.Dad let me drive his CJ2 in '48' Did lots of service calls and plowing w/ F head wagon during '50s at garage. Been building other peoples toys for 65 yrs, it's time I had one. Have a blueprint 215 on stand that customer didn't take. They're great little engs. Remember the Specials at the shop early '60s. Want to do a neat job or I'll stay w/ the Hurricane. There's a few 153 and 181 chevs here. That's a sensible swap that's been done by some, but wanted to learn of pros/cons first. Thanks, David
