It'll be a long time before they completely get rid of em, but I'd expect to see LS-derived motors with special distributors to utilize the new head designs and such on a computerless old-school type motor.Originally posted by novaderrik:
they still put the "old style" big blocks in 3/4 ton HD and bigger trucks- the big 496 (or 8200 in Vortec speak) is essentially a tall deck big block with LS1 style heads on it. so the "old school" stuff aint totally dead yet.
it's progress and economics- the new gen 3 engines are simply amazing and are already in everything from big trucks to the Grand Prix and everything in between, so it makes more sense to use the same engine across as many platforms as possible.
i wonder how much longer before they start phasing out the crate motors and replacing them with even more potent LS derivatives and sell them with an oil pan that will clear any old chassis and generic motor mount adapters to make them a drop in install. 5 years-maybe?
