Default Stock 500EFI dyno sheet

Anyone have a dyno sheet they can post or email of a STOCK 500EFI? I tried to search for one but the search function picks up on way too much.

Either or both will work. But I thought the EFI only came with CMIs?

Disclaimer: this is not my engine, not my data, rather it is info someone posted as a legitimate stock 500HP dyno test. With that said, it looks correct.

The 470hp is at the prop and should cover an engine at the low end of the production variability.

Cutting and pasting from Excel was a little messy. Here are the columns

1) rpm
2) hp
3) bsfc in lb/hp-hr
4) fuel consumption in gal/hr
5) torque in ft-lbs
6) BMEP in psi

If you want the Excel file, post your email and I'll send it to you.
