Friend did a re-ring /bearings and hand held hone job on a 350ci whilst putting in a XE 268 hydr. cam.
Beast would start and by the time he jumped outta the car to adjust timing, she'd die.. He tried this a couple of times and noticed carb and fuel pressure regulator had sprung leaks... Decided to shut her down for the day and gave me a call as I had a neat 600 Holley ready to go... so to speak.
He put on a decent spare regulator with the know good Holley. This was 2 days after the engine would not keep runningas gas was leaking..
He turned the key, and, instant friggin' blast came outta the psgr. side muffler.. I was on this side looking for leaks, Holy GeeMoly the front of the muffler was "bowed out" and the seam almost split.
Friend looked at me and he said I was white.. I really did not expect this... Was there residual gas left in this muffler for 2 days, and when she caught, she exploded??
Good end to story is, engine runs great with carb. How could there be liquid gas or vapors in only one muffler (psgr side) out of a dual system for 2 days???
Oh yeah, nuttin' to worry 'bout me boys, my skin color / heart rate - normal again..
