Cross-post from another maillist -- a 520HP 'Vette in 2003?
"GM intends to build 2003, '03 427 Vettes The engines are all individually
labeled RPO-LS88. Which I presume is to resurrect the famous RPO L88 427 of
'67.
They are to all be 520+/520+ (minimum specifically targeting the Viper) The
engines were designed by LPE, and in head to head testing with the LS6 big
block proved more reliable thru GM tests. So GM also commissioned the
building with LPE.
Looking at the test sheets from several motors, I know these motors are
building some 530+/530+ but the spec is to 520/520.
When I arrived at LPE there were 50 GM Mass Shipping Engine racks (each
holds 4 engines) being loaded on a truck. In his shop there was easily
another 50-60 in the works, and in the back staging room another 150 in
various states.
So my guess is they are "pre-building now" for assembly later.
Also I would guess the '03 vette's engine option code to be none other then
RPO-LS88..."
