My L6 acted 180 that of my BB 396 which had a 12-1 and you couldn't get it fire off On Pump gas Not even by pushing it @ 45mph in 4th gear. But drop a little 110 down the carb and it would fire up and Run But Once the motor was stone cold again NO Way it fire.

Here was how the motor went. a 307 12-1 pop-up Fly cut .225 Still had a good size dome and a 194 head milled.Back In 84 I had asked Glen Self and a few others what they thought the copression may have been and they all had said with Out really crunching the numbers that motor was in the range of 13.9-1 to 15-1. Mind you if I took the car to the track It would Maybe??? make 3 passes before blowing that gasket. But it would run pretty much for ever on the street as Long as I did not get on it Hard to offen.another words Not RPMing it over the 6000 mark If i pulled it past that The gasket would blow. with out a dout.
