Alright guys, I'm rebuilding a 427 big block out of my Dad's 427 corvette. The corvette 427 is already race prepped but needs a complete rebuild. I want to make around 500+ horsepower. Do you guys know of any 427 engine packages dynoed? Two important things I need to know is what kind of cam, I know I want a hydralic roller cam, but what type? Also type and compression for pistons??
Thanks guys for any help. Ow, by the way I'm converting this engine into my 69 camaro.

if you want, i can give you info on a site where you can get a program for free. it's called drag strip plus and when you add all of your info, it will give you a horsepower rating and suggestions on better parts, you 1/8, 1/4 mile time, speed and so on.
then you can play around with your engine size, and parts to see what will work better for you before you go out and buy the stuff.

I would recommend calling one of the major cam manufacturers. They can help you figure out which cam and what components will get you into the HP range that you want to be in. I called Comp Cams and they were helpful. You can reach them at 1-800-999-0853. They will want to know what rear gear and type of useage you are planning for the car. They recommended a Xtreme Hydraulic instead of a Hydraulic Roller for my 427. Scoggin Dickey is also a good resource.

I agree with Kwissman. Call the tech guys at all of the top cam manufacturers and they will be happy to make recommendations. A firend is a QC tech at COMP Cams and they have tons of dyno data. Also, there is a site called that has a good, fast, tech repsonse email link. "ED" seems to be very knowledgeable.

Thumbs up

Look into Edelbrock! They sell kits (heads, cam, intake and carb) already dyno'd and HP rated.
