Mark Maras Posted February 19, 2016 Share #85 Posted February 19, 2016 Welding itself is not difficult if the conditions are good. What makes it difficult, even for a pro, is contamination and crappy fitting parts. Much like painting, most of the work is done in the prep stages. Clean steel and minimal gaps (1/16" is too wide, 1/32" is good) make welding a lot easier when butt welding thin sheet metal. Care in fitting the new steel to the old will be rewarded. The finished work will look much more professional. 3 Link to comment https://www.classiczcars.com/topic/51541-1973-rebuild/?page=8#findComment-486824 Share on other sites More sharing options...
Matthew Abate Posted February 20, 2016 Author Share #86 Posted February 20, 2016 Planning to use shield gas. Chuck Buczeskie is going to send me a list of supplies to make sure I have everything, but that's a great tip on the settings. Thanks. Thanks for the spacing tip, Mark. That gives me a better sense of how to cut the car prior to clamping. I think I'll spend a month or so practicing on scrap, or at least until I can make a clean weld with good penetration without warping the metal. ... In other news, my dad just called me to tell me he nabbed an F54 block and a P90a head for my birthday. This was an unexpected surprise as I had planned to run the engine I have until I had a sense of what I wanted to change. I think he really just wanted another engine rebuild project to do, but I'm not going to complain! Any tips on how to proceed with that are much appreciated. It'll definitely be NA, so I will repurpose as much of the stuff on my current engine as possible. /M Link to comment https://www.classiczcars.com/topic/51541-1973-rebuild/?page=8#findComment-486867 Share on other sites More sharing options...

Matthew Abate Posted February 22, 2016 Author Share #92 Posted February 22, 2016 Some pics from the block inspection: ... Looks like someone turned the crank with the head off. The chain is trashed. The cylinders still have cross hatching. A quick check puts them in at 85.725, but need to double check that. Factory is 86.1, right? All told, this was a very good purchase.
