So if I'm not mistaken only around $11k over a stock LS7 crate engine right? Sounds like a deal for a fully built motor! You would not happen to have any extra 500ci's track attack engines laying around collecting dust in the back of the shop somewhere would you?

Katech_Zach

Roughly speaking depending on how much you pick up your base LS7 for. The list price is $19k now. I believe Summit or Jegs still has some at the old $13k or $14k price.

Oh yea we've got stacks of 500s just laying around.

Werks

It was worth a try Based off of the new list for a stock LS7 then this makes it an even more attractive deal for someone! That's a lot of motor!

Are the 610hp 570ft-lbs figures at the wheel or the crank? If these are crank numbers, can you tell me what drive train loss % you use to calculate down from the crank numbers or up from the wheel.

Cheers.

Katech_Zach

Those are actual crankshaft numbers from our engine dyno. No calculating going on here.

512BB

Thank you. As a follow-up, can you tell me the % drive train loss for a 2008 Z06? Alternately can you tell me what wheel Hp and Torque I should expect with this engine?

Cheers.

Katech_Zach

Depends on the chassis dyno (why I don't like them), but a good rule of thumb is 12-15%.

512BB

Thank you and I totally agree with you regarding the chassis dynos as there is a lot "adjustments" that can be made that changes the whp. The true measure is the engine dyno.

Do you guys follow SAE or DIN standards?

Katech_Zach

The correction factor is STP J-607.

512BB

Thanks for the response Jason. Sharing your engine dyno correction factor shows genuine quality in your work as it gives customers and potential customers the most accurate information.

Cheers.
