I'd probably be even worse at TIG welding. I've seen a few folks say they have a bored and stroked out 5L L6 using the 292 crank, but really haven't seen any details on it outside of them using Chevy crank balancers.

I had to cut a bunch more material out of the exhaust manifold's heat cross over. I'm glad I had already started to do so because it turns out it would have been required. But I bolted it all together on the head and cleared up any interference's, so now the only place the exhaust manifold is connected with the intake manifold is at the head and hold down bolts. Now the next step is giving the welds a coat of epoxy, then a nice coating of Pontiac Blue engine paint.
