UPDATE 06/07/09: Getting back in the game.
I've been quietly searching for an engine to build to replace the purple 454. I found a smokin deal on racingjunk for everything to build the engine except the heads. Picked it all up today.
Here's the basics:
BBC 454 bored 30 over
Flat top pistons
Erson Cam (288 duration, 492 lift)
I've decided on a set of Edelbrock Performer or Performer RPM aluminum heads. 110cc chamber. This will put the compression right at 9.5:1. Now I just need to find a good set.
Time to start building...
