What size engine for the online/Youtube EC?

That’s workable but I’m not understanding the displacement rule exactly.

The rules say 360 block and a 3.58 stroke with up to a .040 offset.

Then it says a bit later any displacement is allowed because of how the results are calculated.

If thats the case, why not allow a 340 block that’s not an X/R/Ritter?

Also, I didn’t see if there was an RPM limit or if the results are calculated from a low RPM to a high RPM determined by the rules ie. 2500-6500 and calculate the results.

Or can you run the RPM up as high as your gut will let you??
The .040" is to allow indexing and undersizing and or a few more or less cubes.

It doesn't say ANY displacement allowed, but if someone builds a re-ringed 5.9 @ 360 ci and another builds a .060" @ 371 the scoring formula takes care of that. 1 ci = about 6 points usually

I will make a change to include the 340 block--I don't have a problem with that.

The RPM range hasn't been decided yet. J.Rob
