Here’s a 1999 Pontiac Firebird Formula owned by Dale P. of Burlington Ontario. Dale got tired for the stock LS1 engine and opted for an LS7 aluminum block with custom Harrop intake. At last check on the Wildgoose dyno it put out 705 HP & 663 ft./lbs of torque. That’ll shred some tires.
Here’s a dyno run on the LS7 engine at the Wildgoose shop.
