85% V.E. is realistic for most builders of mild street engines.
And I'm pretty sure that we are talking about "most builders of mild street engines" here since 99.9% of gearheads don't have multi-million dollar facilities nor the vast expert knowledge it took to afford those multi-million dollar facilities. Even most of your average in home drag engine builders who are producing engines with 1.4-1.7hp/ci are still only managing 85-90%VE
