I took the car apart so I can go through the whole thing from the ground up and have a nice Hot Rod in the end!
Please check out some of my other videos!

I will be doing the same thing on my 75 in a few months. I would strip off everything you don’t want sand in unless you can find a way to seal it. Sand will get EVERYWHERE!
When you grind your tungsten, grind in line with the wheel not across it like that. This leaves the scoring marks left in the surface of the tungsten by the grinding wheel which causes the electricity to flow better to the tip and will make it not only weld better but last longer.
Also I would invest in a 2nd 4" grinder and keep a Scotchbrite disc chucked up in it. Any time you need to get that garbage off the surface it will do a much better job without gouging the metal.
Personally I would have stripped the frame and sand blasted before any welding work. Also any time I am welding a frame around an engine like that, I will pre-heat it with a torch to remove any oil etc that may contaminate the weld.
Thanks for the tips, I’m an amateur welder, so I appreciate the advice!
Yeah torching the areas first would have helped a lot, because oil and grease kept seeping out of the overlaps in the frame when the heat got to it.
I'd recommend making a removable transmission crossmember. It makes working on/removing the transmission so much easier...especially I've you're working with a Tremac 5 speed which is larger than the stock Muncie. There's kits can be purchased for about $100. Welding required.
I agree 100%! And that’s exactly what I did after the frame coating was already painted on.
I should have done beforehand but didn’t think of it.
Cool video but those welds look questionable, hope that car turns out to be a real nice c3, YT has been pushing out your videos in my feed SOOO much ever since today so I have been watching your videos and ima fan
Yeah, the factory welds are bad and mine aren’t much better Lol. I figure if it lasted 50 years with the bad factory welds, then any strength I can add to it should only help the frame survive longer😆
Well, I’m glad to hear it’s pushing our channel, it’s crazy how the algorithm seems to have a mind of its own!
Thanks for watching, and for the encouragement!
Where did you get the gusset kit?
Poor welds, clean welded area for tig.
That looks like it s going to be an awfully small car!

Yep, just a 2 seater with no trunk! They are very small cars compared to late model corvettes.
