Made 500 EFI's 540's with 9.75 compression, ported Iron Eagle heads, monoblade intake, etc. Looks stock but made 630HP and 700TQ with all accessories turning.
Wouldn't do it again for the money. If you want to cruise at 60mph, just push the sticks forward til your there. Rebuilds will come quicker that way but it's still the cheapest way to go.

The Whipple or Vortech kit will make about 700hp on a 500EFI.
