Looking good, Bob
I am a novice on cam nomenclature. Why will most be disappointed? What do the numbers mean. What would be better to "most"?
Thanks
Ben

If you Click Here at this chart of Buick Nailhead street cam recommendations, most people would not even be happy with the smallest because it wouldn't have enough or a lumpy idle. That is why Comp cams doesn't even make a cam for the Nailhead that isn't a "Thumper". To most the idle is everything, performance and drivability is secondary.
I don't have the specs on the cam I have installed, but it is a Schnieder close to the 262-70H one shown on that page. Won't have lump, but I it will be comfortable and affordable to drive.
Been making some progress on the 425. Lots of details go into fitting the 2x4 set up. Modified kick down, never quite figured out exactly how it was supposed to fit on to the carb. I removed the existing fitting and built a new one. Found the correct kick down bracket was available, but at $150.00 - 250.00, it was a little rich:( so I decided to build my own from two regular kick down brackets.

Built a fuel line, but I had interference with the air cleaner :( I will have to rebuild the filter to coupling line and rotate the line down a 1/2" or so to clear the air cleaner.

I used an insulating product on the exhaust manifolds, then covered them with POR manifold paint. The paint did not stick as you will notice.
You can give me a hard time over the dramatic film start:D
Sounds good Bob! The idle is smooth and the motor gets right with it. Is it drop in ad go now or is there a lot left to do on the car?
I have to go through the transmission, do some interior work, and decide what to do with the rad. Not too much, but we have too much happening this summer, including a complete kitchen and other summer happenings:(
Bob, I could not find any reference to what piston you used in your buildup of the 425.
Bob, I was not clear enough, I was inquiring about the brand of pistons you used.
Yes, you were, I suffer from fuzzy old brain disease:jeez:
