Can you share the rotating assembly specs? On the 270's, is the exhaust port raised and does it create any header problems? Was it built on a 400 or 440 platform?

Rotating assembly is off the shelf. I think that engine had a Molnar crank and rods and Diamond pistons. It is a 440 block with a 4.25 stroke crank. The exhaust port on the 270 heads is in the stock location or close to the stock location. I'm not aware of any header problems but who knows, most headers don't fit anyway so how would anyone ever tell?

Thanks Andy., you'll have to do a second edition book with the TF heads.
