I spent time last night tearing down an early SBC that I traded for a while back. The codes indicate it's a late-56 production date for an early 57 4-barrel Powerglide car. The heads are later Powerpacks from 62-67, but I have some staggered-bolt heads coming. My plan is to polish this turd to a mild runner, not interested in making 250+ hp! It will eventually find its way into my 31 Tudor. I'll either paint it orange (for that just-pulled look, or black for covert operations...either way, it will get mated to an early Ford trans. I stripped it down to a short block and flipped it over to inspect the bottom end. I pulled the #1 connecting rod cap and the #2 main cap just to see what the bearing surfaces looked like. Here's what I found... Connecting rod Main cap Now, my question....Assuming the others are in the same condition, would you run this or have it machined?
