273 power? HOW?

I've got an aluminum 4bbl Edelbrock SP2-P intake that I just pulled and had tanked at a machine shop. It's got intake ports that are great for a 273 or 318 velocity-wise, and it's got mounting provisions for spread-bore carburetors or square bore carburetors with a small, commercially available adapter. It uses the same bolt pattern as the 318, 340, and 360 to mount to the heads.

I'm currently asking $140 obo. If you're interested, drop me an e-mail.
