| COMMENTS: | The company’s LS7 wet sump crate engine makes 505 hp and 470 ft-lb, the same as the GM dry-sump version in the current Z06 Corvette, so it’s ready to drop into a C5 Vette or F-body without having to deal with an external oil tank. It also has a 24X reluctor wheel, so it’s good to go for earlier-model computers (though a 58X can be had as well). LS1 to LS7 conversion harnesses are available, and options include H-beam forged rods and forged pistons (9.5:1 to 12.5:1). |
