Obviously Katech are the leaders in naturally aspirated LS7 race engines; their records speak for themselves.

By the title I thought you finally broke down and decided to replace that poncho motor with some real muscle.

Another Vote for Katech. You cannot get a better more reliable racing LS7 anywhere. Just take a look under the hood of every LeMans winning C5R/C6R. All Katech built, and they have won 8 straight championships.

Who else can make that claim?

I'll second that. Nascar Busch North and Busch West (now Camping World Series) spec engines are LS based and were designed by Wegner. Probably a more economical choice than Katech if you don't have the budget of a factory sponsored team.
