On this 1971 Chevelle SS we are rebuilding the LS5 454 engine. It will outperform the LS6, ZL1, & L88 options available for the ’70 with the rebuild. Well over 500hp.
Chevelle Engine Trivia: The LS6 option was not available on the ’71, after ’70 and the ZL1 & L88 options were race only engines with VERY few making it into production cars for the 1970 model. These reductions were both part of emmisions and insurance restrictions that reduced compression and horsepower.
