Ok so ill try to keep this short, Ive been building this old Cuda for about 5 years now and I'm almost ready to fire it up. I had this 408 LA built about a year ago, I had to swap oil pans because the Moroso It came with sat to low to the ground. when I pulled the pan I could visually see up and down scratch marks in cylinders 3,5 and 4. I couldn't really feel the marks with my finger but they were there, Unfortunately I didn't have the for-site to take pictures. The engine was only run for the dyno and I was pleased with those numbers. (I didn't see it run.) After much digging around the site I've come to the conclusion that there probably from the builder failing to clean up the ends of the rings (debur). At the time I told myself it would be fine and just to run it and see how it goes. But I cant seem to get it out of my head! Is it something i should fix before I start it up. I know what everyone is going to say. Send it back to the builder, but logistically that's a nightmare for me and I'm not sure I'm willing to wait another 6 or 7 months for them to get to it and its a couple states away. So the question should I go ahead and run it and see how it goes? What damage do I risk by running it? Would the smartest thing be to just tear it down now? 408, fully forged, KB pistons, 10 to 1 CR, eddy heads, Howards cam.
