Sometime mid-80s I recall a buddy shopping for engines for a project car of his (basically porn browsing). His budget for a 350cid chevy engine comparable to this would have bought 250HP to maybe 300HP, as I recall.

This probably can be expected to run for what, 3 or 4x the lifetime of a 1985 custom build? with service requirements of about 1/3rd the older unit?

in other words wow they're getting good at these. I didn't check the weight but isn't this near or into "aircraft capable" territory?
