Updated my website with a dyno results page....

I believe that could be due to the removal and reinstall to address the head gaskets and or the intake gasket... then again it could have simply been the stretch in the throttle cable.

The main difference in the car he mentioned to me was pulling off the dry sump.

But yeah, the chassis dyno is a world of difference in setting up the car with the engine. Too bad ours was not completely installed when Gary's car went through since it would have been good to baseline it against 40 other or so engines in the same car by different builders etc.

Keep working on the charts, it's a great resource to offer.

Thanks.

As long as everyone remembers that dyno numbers *should* be used as a general tuning tool, things shouldn't get out of hand. However, my intent was to just show what typical engine combos make, where they make the horsepower, etc. Its nice to be able to look and see what difference a set of heads can make, what difference a camshaft should make, etc.

And what David says holds true in every respect. It's very difficult to dyno an engine here or build a carb here and it be in perfect tune as you send it to a different region in the US.
