I am original owner of a 64"E" coupe with a 3.77 rear end ratio. This car was very fast. At the high speed the car flattens out and sort of hesitates and ocassionally coughs. I have checked / replaced all the things you can think of. Replaced a new SU fuel pump etc.The distributor is original, todate I have not replaced it, however I obtained a new Petronix complete distributor ready for installation. The C.R ratio is about 155 psi in all 6 cylinders.
Please any ideas.

Like Mr. Brady says, it's probably timing. Make sure the rubber boot at the vacuum advance on the dist. is making a good seal. I would probably start with a fresh set of plugs too, couldn't hurt.

THANK YOU FELLOWS FOR RESPONDING. I HAVE REMOVED THE AIR FILTER COMPLETELY. THE CARBS ARE OPEN. INTERESTING,. I BELIEVE THE PLUGS ARE GAPPED AT .025.
