That welding helmet is awesome! I gotta get some kitty cat and unicorn decals for my helmets.
Not for back pressure exactly, though it does create some. I know it doesn't make a difference on the stand since there's no load on the engine, but I just don't want to risk a lean spike with those really short headers. And I want to set idle mixture and timing with conditions as near as in the truck conditions as possible.
A friend asked why I built the stand to mount the engine so high. I told him that I want the engine at the same height as it will be in the truck, because altitude affects carburetor tuning.
Ever since I assembled the valve train, I've been slightly off my rocker. Literally. I teetered back and forth about fixing it or leaving it be. Now that I'm ready to put the engine on the test stand, I couldn't just leave it alone.
Some of the rocker arms were not lining up dead center on top of their valve stems. I'm talking about "X" axis. Some were slightly off to the right, some to the left. The cylinder heads came with one piece pushrod guide plates, which were identical to the Manley guide plates I bought for the D0VE-C heads that I decided not to us. Anyway, I played musical guide plates until I just couldn't get anymore to line up properly. I thought about cutting them in half, lining up each rocker individually, then TIG welding the guide plate halves back together. So this morning I contacted a couple of builders. They both giggled and said "welcome to engine building." Turns out they both do this fairly often. It's too bad nobody makes two piece weld together guide plates for 460's like they do for SBC's and SBF's. Anyway, I had to cut and weld two guide plates on each bank. All the rocker arms are lined up properly now!
First pic is of the most misaligned one.
Here's a guide plate cut in half.
After getting the two halves of the guide plate lined up, you can see how much I had to shift them, in order to center the rocker arm.
I'm not a world class TIG welder, but those rocker arms are centered now!
It has been a fun and educating ride for me. If I can figure out how to post video's to youtube, I'll do that when I run it (or destroy it) on the test stand.

Thanks Brother.
I think I have an account on youtube. And I've got the last iphone muti-magnum gazillionite phone that was before this new earth encompassing megaloid calculus interpreting phone they just came out with.

I got it on the test stand tonight. Working in that already overcrowded room with an engine hoist, engine stand, and engine test stand was a bit of a contortionist act. The lift points I put on the engine worked out great. I've got a lot of little detail items I have to take care of before I can fire it up. Make a throttle cable bracket, wire the ignition box, make a set of short exhaust pipes and attach mufflers, etc., etc..
Hell Yeah Brother ! I'm excited for you I even offered tobacco
Thanks Brother! I'll get my long turkey harvest pipe out. I have a tradition of smoking a pipe after a turkey kill. Seems appropriate to have a smoke if the engine build is successful.
