Diabolical update
I promised I'd post when I finished. I'm all done except for the dyno tuning. So, I don't have numbers yet. But I do have plenty of pic's:

Dave looks good. I had the same vacuum pump, but was trying to make it work off the crank....did not think of putting it up there and eventually sent it back, since I did not have the time to mess with trying to make it work....got me thinking again now....
550rwhp is going to be pretty stout to achieve with a low compression 427CI motor, that would be 660 motor hp assuming 20% through the drivetrain...
These motors barely make that much with MUCH higher compression and more cubes...http://www.shafiroff.com/434_sportsengine.asp
Hope you make it to your goals though, I know you have been working hard on it.
Are you going to run it at the track at all? Keep us posted with that you come up with....

Hey, that reminds me... This is risking highjacking my own thread, but I just posted a link on the website to a magazine article about the guy who builds the engines I sell (and he built the engine in my Vette). Jeff Dickey is his name. Here's the link:
http://moparmusclemagazine.com/techa...0602_dyno_web/
He won this competition, which is huge bragging rights for him. I'm proud of him.
EDIT: Actually, after reading the article more closely, I'm not sure he won. Jeff came back saying he'd won. He made the most hp. But, reading the article they say they factor in cost and idle vacuum. So, I guess the jury is still out (unless Jeff already knows he won the combined total).

That's the pressure plate. It's rated at 1000hp
From Doug Herbert Performance, in West Palm Beach, FL: Mr. Gasket Part No. 10-330 was $219.99 That was the SFI flywheel.
From JD Engine & Machine, in Columbia, MO: Hayes PN 40-121 was $102.62 That was the clutch.

Dave did you have spacing issues or stack up issues with the McLeod TOB # 1345?
I am going to pull my Centerforce DF II Single mass setup out next weekend and I want to go back to the McLeod TOB with a push type clutch.

NExt question, how does the stack height compare the OE set-up?
I have a nice Fidanza Single MAss flywheel, if I could convert to a push type with a Hydraulic TO bearing that would be perfect.
Is the flywheel you are using the same thickness as the old Dual mass?

It's been awhile, but the way I remember it, the McLeod comes with some pretty specific instructions on measuring your clearances. My stuff just happened to fall within the allowed limits. "I'd rather be lucky than have a license to steal"

Here's a video of a little burnout:
