There is a numbers matching L48 350 out of a 1971 vette on Ebay #180364151495.
Block number "CJK". It's appears to be all original with 487 heads. It's been dyno tested
356HP and 385 TQ. Is this the correct block stamping code for a 71 vette? If so would a complete dyno tested 1971 L48 350 be worth what they're asking?

Thanks
