Hey, if you have over 400 inches you won't miss 1 inch.

I would be very satisfied with one less inch and i'd look like this-->

Very nice, Todd. And the legendary 427CID. Be very interesting to put a
DOHC 427 v the LS-7.

Just something different . Actually opening the chamber up like that helps airflow a bit, and let me run a smaller dish volume in the piston. I needed that, because of the very short piston height I am running w/ the 6 in. rods.

It is also not unlike what Lotus did with the next-gen LT5 which Graham showed at BG 08. See newsletter issue 15. Also this design is similar to any Cosworth or other 4-valve race chamber.

Todd,

Does compression ratio change much?

The chamber is still only 49cc. Compression is around 12:1.
