Breaking in on an engine dyno can be done very fast in a matter of hours. Afterwords, these were the instructions given to Sergei.

My shop has built a dozen or more S65 and S85 strokers and dozens of other S65 and S85 engines. I'd say what sets this build aside is having an Indy-500 winning engine builder do the job. Everything is measured and fitted. If it doesn't fit to an exact specification, then parts are machined until they do. Cams were assembled and probably timed and re-timed three times until there wasn't even a 1/2-degree slop in where they sat or opened/closed the valves. I'd say this is the quality you get from an Indy-500 winning engine builder.

I'll see if I can push Bert to get some pictures of the build.
it sounds like an incredible build, congrats to everyone involved. imagine what the times would be with a prepped track and a little less weight in the car....great job.
