If you haven't checked it out yet. I also have a thread in the Active Thunder section of the Make Over of my AT that these are going in, paralleling this thread. Another 5 minutes of entertainment for you.

After a long process I finally made it to Smitty's (articfriends) place.We spent 2 days tuning and trying different things. A few snags and technical difficulties, but all in all a big success.
Any guesses? 461, 9:1, 237°/243°, 0.646"/0.686", 2/3-4/7 swap, ported heads, 87 octane.
