Thanks to the guys at AES, my shortblock is now done. They did a good job, and were pretty patient with me during a few delays. Getting closer... dyno by spring!

Todd,
Your short block looks fantastic. I stopped by RFD yesterday afternoon and Curtis had your heads boxed up and ready to ship. Best of luck with the rest of the build and keep us updated.

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.
