My '75 350 slc Euro lost power and started making a horrible clacking noise. I checked compression. cylinders 1 thru 4 175PSI 5=0 PSI 6=90 PSI 7&8=0 PSI. Removed the valve cover to find a considerable bit of chain slack.
Is the 350 V8 an Intereference engine? If so, is it possible that I just skipped a tooth or 2 and didn't damage valves?
Can anyone explain cylinder 6 having some compression while 5, 7, & 8 have None?
Where should I go from here?
Thanks for any help.
