Finally got around to starting the '57 rebuilt 235 (from a bel air in a "53 truck). I know from reading the forums the proper way to do it is to run it for 20 min or so even if it doesn't run great to break it in, then do adjustments. My question is below. I'm not the mechanic, my cousin is, and he kept wanting to start it for a minute, shut it dow and adjust and do that over. He did this 3 times as the carb needed adjusting, the timing was a bit off, and i know the valves need some adjustment. When i said I'd really like to just keep it going for 20 min (which i believe it would do) to make sure oil gets everywhere, he took great offense that i questioned him instead of just saying how great it was it would run (which i did do, but apparently not enough). I'm not a mechanic and he thinks this is the way to do it, that is, he says getting it running better before letting it run for so long is the way to go. When i told him what i read, he said to let "those" people work on it then. We are friends, and this didn't cause a huge fallout, but before i go back, i just want to know how horrible it would be to just let him do it his way. Oh, and we did use assembly lube and primed it really good. It also has all stock parts (cam and such), if that helps. Thanks for any advice
