We did an engine upgrade about a month ago using a 4.9L Cadillac engine with the 4T60E transmission.
The engine looks like it belongs there especially since we used the Cadillac airbox with a K&N filter ducted to the side inlets
It's a subtle change when viewed through the hatch and decklid
The car dyno'd out at 161.2 HP and 241.7 ft-lbs of torque raw.
It was a very hot day when we ran it on the dyno so it needed to be corrected for temperature
The corrected power was 172.5 hp and 258.6 ft-lbs torque at the rear wheels which is about 302 ft-lbs torque and 201.8 hp at the crank
The car now has neck snapping torque off the line and ran a best of 14.81 at 96 mph, but it was hitting the rev limiter and we had to back off to make it shift. We have a new chip coming and it should put it into the mid 13's.
