Steve, Looking forward to seeing you again. Welding the .040 6061 is with either tig or gas - depends on the guy welding.... but with tig be sure to look at root side - may need a second pass to withstand the post-weld work with the thrashing hammer.... (oxy-acet, .040" - 1mm - punished on the thrashing hammer.) I shrink the T6 - cold, as is. I used to be so respectful of it, and field anneal just so, and quench and go ... but then I guess I got used to having a kid brother around to beat on, and things changed a lot. For the amount of shape you gain by shrinking it is worth the struggle -- and the strength you get is ideal for your task. What block? bbf is always Holman Moody 427 in my mind ..... yet the drag guys next door pump 9k+ hp now from the billet blocks ....

Thank you vary much Kent for your time and your willingness to share your knowledge.
Another question I have about the weld is should it be cut down with with a die grinder or sander to reduce the amount of metal being hammered back into the panel causing over stretching ---- or ----- am I overthinking it and it is a non issue. The block is a later model 429/460 stock cast iron block. It is out of a drag pack car and it has 4 bolt main caps bored .080 over with 4.50 stroke crank.

I always check the root for "stalactites" and these I dress off with some sort of accurate cutter/abrader - before the little band-sanders arrived on the scene we used die grinders, which were not especially smooth-cutting. The band sanders can travel sideways and hold a pretty good level that levels evenly, and level sanding helps evenness of planishing happen.

Time to make paper patterns that fits the buck to transfer to aluminum sheet so I cut a piece of the width I wanted.
As I wrapped the paper around the buck huge buckles developed in the paper. It just didn't make sense to me. There wasn't that much shape in that area. Then I had a A--HA moment. ----- What if I let the paper relax and let it lay flat against the buck ---WOW. What a difference letting the paper lay where it wanted to lay. Where it Wraps around the nose there is a parting line on the center line. This is the lower pattern folded in half. Making the top was no problem. Now that it's done that was cool

Great!
This one is iconic! Very, Very nice. There is one here in CO that the same car is being turned into an itch mobile and I want to cry every time I pass his place.
