Thanks for those Dave! Could I trouble you for a measurement? Could I ask for the O.D. of the distributor just above the intake? If it isn't to much trouble???

I also notice your PCV is on the left front of the motor. Where I usually set it to the right rear. Works the same I know, just a different approach...

Is that the fuel filter across the rear of the intake? I'll bet you never expected so many questions from 2 pictures!! LOL..
