[Diy_efi] engine convresion

[Steven P. Donegan]

Almost sad when you think about it - my 1998 LS1 V8 gets 22 MPG around
town and has seen 35 or so MPG on trips - likely about twice the HP of
that 6 :-) Of course that car has a 6 speed manual tranny with 2
overdrives (.85 and .5) and likely weighs a bit less than your 87.
