Get it done and sell it and give the money to your kids. Vintage cars will be stationary museum pieces in the future and as such only the most rare and pristine specimen will survive. Internal combustion vehicles based an gasoline engines will be extinct by 2040-50.
Within the next 10 years, I will liquidate my "fleet" of 16 bikes and 2 classic/collector cars.
1973 CB350F -sold
1974 CB350F -218 orig miles, sold
1976 CB750K - in restoration

Other Hondas:
3 x CBX
CB1100R
GB500
Plus Kawasakis, BMws & Ducatis

 There's a guy near here working on a revised version of Mickey Thompson's hemi heads with a blower intake for Pontiac. That would be amazing to see finished.
  My experience has been the Pontiac bearings let go when you decelerate. On the track you can't throw a turbo 400 into neutral after the run so there aren't many choices. I have a ram air IV pan and pump on it. It's a 53,000 mile 400 motor so it's a good starting place, I'm thinking .030 overbore and a 455 stroke. I think the Edelbrock cnc ported heads are pretty standard these days.
No matter how many times you paint over a shadow, it's still there.

 I know where a couple guys are with a private bike museum, I think there's over 1200 bikes. Not everyone has to choose lol.

Butler builds rods and blocks with splayed and serrated main and rod caps. They don't spread easily.
They rods are similar to BB cheverolet from what ive been told. Pontiacs are no longer limited to 6500 rpm....
How about a build thread somewhere on here? 8)

total modernization of the Pontiac engine, all of the old weaknesses addressed.
Able to run with the big dogs now....Oh man, I miss my old Grand Prix.  :(

It's been a while since I played with Pontiacs and yes I miss my 78 T/A, 65 GTO and most of all my 70 GP but all the old weaknesses addressed? I'm not so sure about that because Poncho's had a bunch that were inherent in the design mainly cyl heads and block. It's been almost 20 years so a lot could've happened since then I guess but it's hard for me to imagine it. I will agree that Butler does build some wicked Pontiacs though. Way back in the 80's a friend of mine and myself were at Union Grove Raceway in Wisconsin with our Pontiacs and spotted a Poncho in the pits with a tunnel ram and seeing a tunnel ram on a Poncho blew my friend and me away. The owner of the car turned out to be Larry Wenzler.

Scott....just an example......(sorry for the hijack Don, hope the bird turns out well)

Hijack? What hijack? How often to you get fellow Pontiac enthusiasts together? ;) Sorry anyhow Don but I hope you understand.
The IA block was making its debut when I got out of the car hobby after selling my GP years ago and yes the IA block is cool but that's going to extremes in my own opinion but for all I know that may be the extreme Don is looking for.

Well I do still have a 445 crank that's been neutral balanced for BME aluminum rods, you'd still have to take the mains down to 3" and weld up and remachine the thrust bearing journal to work in the 400 block ......or just buy an aftermarket 455 crank that's already been machined specifically for use in the 400 block and probably cost less than it would take to make my 455 crank work in your 400. I still have a few go fast Pontiac goodies just in case my finances allow me to build one the way I want, I don't see that happening anytime soon but hey you never know. :)
