318 power?

What most who never tore an early 340 down don't realize is, the internals were some of the best components available at the time. It was designed to rev ...I ve heard old guys who were around when they were new say "they were fast right our of the box..." meaning off the dealership lot. Then do some day 2 mods and it really ran. Get some Mopar performance or Direct connection parts and get it dyno tuned..400 horse easily. It was definitely a bang for the buick bargain package.
