Thanks Lee But i have been dealing with autolite for some time now and I run the Race plug from them. So far most my engines Like The autolites the best. I got hooked up with them many years ago
and have tried many plugs. Even running different heat ranges from 1,6 -2,5- 3,4 The different ranges Made a difference when I had the Offey intake.I'm sure the clifford single would have been pretty much the same as the offey.But not a lot of difference when I ran the clifford dual and with mine I went to one range across the board
One other Old trick was to cut the tips and side gap the plugs. that was one trick My BB 396/427 Loved was to side gap the plugs.
which was like the surface gap plugs or the angle gap. }[oooooo]
God doesn't like ugly.
