Chevy 3100 / SSR - Engine Swap
The stock 5.3-liter Vortec V8 was rated at 285+ horsepower.
Not nearly enough. So we're replacing it with a 427 cubic-inch LS2. The
first step is to peel away the layers of wiring harness, etc. These new-fangled
modern automobiles have just way too much of that stuff if you ask us.
Some things never change though... Leave any car sitting long
enough (new or classic barnyard find), and some critter will make a home
in it. When the intake manifold was removed we found evidence of rodents
having made a home underneath it. Nuts anyone?
Out with the old...
In with the new...
The new aluminum 427 sports a pair of AFR 225cc cylinder heads,
Callies cranks and rods, and Wiseco pistons. This motor is supposed to make
600hp and 600 ft lbs. of torque, but we'll find out for sure when we put
it on the Dyno.
The transmission was sent to Horizon Performance Drivetrain
to get beefed up so it could handle the extra HP and Torque.
