Rev limiter set at 8400, shift at 8200.
403ci SBC - N/A 4.135" bore - 3.75" stroke

COMP Solid Roller - 286/292 @ .050" .750"/.730" 112° lobe
Smith Brothers 5/16" .080 wall pushrods

As a note, I built the engine 2 years ago in my garage, dyno'd it, put it in the car and have made aprox. 100 passes and have yet to need to adjust the valve lash from the original .028" cold. It just goes to show you that if you have a stable valve train, adjustments are a thing of the past. Don't get me wrong, I check it after every 5 passes, but I haven't needed to turn a wrench yet. Valve adjustment is an excellent way of detecting a valve train problem before it becomes a bigger issue.
Finally after 100 passes, 20 dyno pulls, and about 40 street miles we broke a valve spring at the track last weekend. I'd say that was pretty damn good considering how stressed the springs are. And I checked the lash to be sure we didn't bend a valve, and it's still good. Amazing, since our PTV is only .080".
