12's on a budget!

Want more?

Upgrade to 1.6:1 roller rockers, and correct the geometry.
Get a good 32-3500 converter


Read the tech articles on your site, very interesting!!! When will more be posted? Any suggested reading or "how to" on fixes


I write the tech articles as I get the time, and the last one was just posted last week. It may be a little while until I can get the next one up there, depending on how backlogged I am with work. The only real fix is to relocate the rocker shafts to get everything in the right place. There are two ways to accomplish that. Mill the stands off of the heads and have someone who knows proper valvetrain set up make new stands, OR, use a bolt on kit like the one John put on his 408. Also, just milling off the stands, and making new stands, to center the roller on the tip of the valve will not correct geometry, and will likely result in valvetrain instability and possible failure.
