not if it's an aluminum aftermarket racing block. i don't think GM's
ramjet crate engine is offered with aluminum blocks though...but in
all honesty, there are a dozen shops that could make an alloy ramjet
chevy engine in their sleep.

i suspect an alloy chevy small block weighs less than an O-540, and an
alloy chevy big block weighs a little more...so you get to choose. i
assume you need a radiator, but not a psru.

given the output of the big block in the neighborhood of 500hp, maybe
it would be fair to compare it's weight/fuel consumption to a TSIO-540
or normally aspirated O-720 or PT6 turboprop.

my reason for starting this thread is simple...i've read a lot of "mad
scientist/decades of refinement" auto conversion stories...only to see
this magneto option in a consumer catalog as a 2 wire bolt in! i
realize magnetos are in $18,000-48,000 corporate-sponsored race
engines, but then you'd just as well buy a 220hp Franklin for the same
money.
