Hi Gang,
Sunday I was warming my truck up for a drive in my '62 up to Lodi, 10 mins of warming up the engine while loading the bed with supplies for the trip, I noticed she was smoking a whiteish haze smoke out the exhaust pipe.
I then tapped the gas peddle, then a cloud of black smoke came out.

:confused:
The temp outside at the time was 76-78 degrees. Also she doesn't have no oomph when engine is at running temp. :confused:
Could the exhaust pipe be loading up? Or could the 235 need a valve job?
TIA,
David
