  1. Hi If you have the original converter you can do A B measurement. In height of the converters, I remember that my original converter moved about 10mm. When torqued to the flywheel.
  2. Finally they arrived, and are now on the Mach1. Seems like good quality.
  3. Hi Check the coil, maybe do a swap test for another, a bad coil can produce that kind of problem. Does the Petronix getting a clean 12 volt ? Spark plugs wire quality ?

I would start with the coil and ignition system then Fuel then valvetrain :-)
  4. Hi Before going to EFI you probably had a mechanic curve on the dizzy. If that was working good build a timing table from those settings. Drive around and take some datalogs. Listen to the engine, and combined with info from datalog etc tune the engine. Don´t forget to look at the spark plugs, even with EFI its a good check.
  5. Bore the motor 0.30 if needed. Refurbish rods, polish crank. Flat tappet cam will be fine, hydraulic lifters and choose the cam after how you gonna use the car and transmission. New timing chain and gears. Electric ignition pertronix, new wires , coil Use the 2v heads they will do fine, change the valve to one piece. Mill the heads for a compression around 9.5 thats about 67.68 cc chamber Maybe a better intake RPM Airgap or similar. New bolts ARP, in critical places. Stock oil pump will be fine, arp driveshaft for oilpump, Headers. Lots of this stuff you wont even see, bu
