I blocked my EGR off because it made my engine missfire horribly when cold. I used a putty knife blade with silicone on it. Runs like a champ, stock everything but the cam, with timing agt 8 or 10° with 87 octane.
Edit your post and rephrase that immediately.
i have heard of some of the cars runnin as much as 11 to 1 back then i dont know for sure though. i know a guy that had a road runner with a 340 in it who said that he had rebuilt the engine back in the early 70s and when they took the lead out that he had to redo it becouse the compression was to high.
