From my inexpert position I'd have to agree with Baron........cam is going to be very important to your setup, and will probably determine whether the car is a dog. Also, making sure your pushrods clear and valve/piston clearance with that cam and whatever rockers you are planning...

Keep in mind, there may be someone on this board with a used cam that could be purchased reasonably, and you could sell the other to recoup the money. If that cam was designed to begin making power at 3500-4000 rpm, and you are planning to shift at 5000........well, it could be a real dog.

If you are going to use the 4x heads you are probably ok unless you want to run a lot of boost. Especially since you have an intercooler. Just make sure your ignition timing is set and operating properly to pull out timing as boost increases.

As for the rest of your setup.......the later year 455's are not as strong as the early year blocks, but I'm sure you've read that already. It is what it is. If I were you I'd spend the most time and a few dollars in your building prep. Make sure your tolerances are correct and everything is clean and goes together correctly as you assemble it.

Hey, I really like the brackets you made! Nice job installing the procharger
