I have a 73 BB 402 +.060 otherwise pretty stock, rebuilt about 8 years ago but only about 2,500 miles on it, runs great but just started smoking blue-ish after full warm up when you come to a slow-down or stop, then clears up after you drive it along again. I have new pennzoil and a wicks filter and it's never been beat...really. Thanx for your help!!!!

Got a choke on it? Could be stuck 'on'

Check the intake bolts. Check the head bolts.....They may just need retorqueing...
