150 IN THE LIFE OF A STREET CAR WOULD PROBLY BE PRONE TO MORE AIR POLUTION , AND NOT GETTING HOT ENOUGH TO KEEP MOISTURE OUT OF YOUR OIL ! HELL my mufflers sweat more than that .
Not if you can get the tune up correct. Most of the pollution comes from wet fuel running into the chambers and either not burning completely or burning so late that it runs EGT’s and head temps through the roof and burns in the header.
