Well since you asked for suggestions.... I'll give you a couple. Please note that this is what I would do, but it doesn't mean it's right for you or anybody else; but, then again, thats the beauty of it, right? Anyway here they are:

1. Put the 283 in mothballs and stuff a pig block in it, 427 or bigger. Remember, there's no replacement for displacement, and there's no displacement like lots of displacement. Cubes rule!!

2. If you decide to stick with the 283 or go with a different small block, remove the Holley 600 from the 283 and throw it as far as you can......unless you prefer to constantly tune the carb? Actually I don't hate Holleys, I even owned one once......ONCE!!! Now since you asked for "good suggestions", I would actually say, don't throw it away. Sell it as scrap, at least you'll get something out of it that way........

J/K lots of luck with the Camaro. I agree with JET,327. Decide what you want the motor to do for you and that will determine how to build it. ie. If you want lots of horses and torque, you may want to start with something bigger. If not, the 283 will be awesome for cruising reliability (as long as you aren't stupid with it....see one of my previous posts for stupidity with a 283, I believe it was in a thread titled "Naming your hotrod").
