Is the 383 rebuilt, original, or what? If its original is it a '68-'71?
Good question. I was told it was a "late 60's" 383 and the heads were changed to 452's to use todays fuels. To be honest, I have not so much as pulled the aircleaner off, let alone a valve cover, so I can't really confirm anything. I can however confirm that it runs good, doesn't smoke or tick and holds good oil pressure. I was told the heads were recently rebuilt. I have no clue what compression ratio, but my guess fwiw is 9-1, maybe less.
Id check the numbers. If its an early (pre-68) engine Id look at another cam, your compression will be absolutely terrible. Maybe even in the 7s. If its a '68 and later engine 9:1 is a decent guess.
