Well, my 94 FW Brougham is a bit modified. The LT1 has a ton of tried & true parts available for it, which is the beauty of these cars in terms of performance. WHat can be done to a vette, Camaro, Impala, etc can basically be done to a Fleetwood...... and before you do it you can get an idea of the gains from other people's experiences.
With my cam, shorty headers, rockers, springs, PCM reprogramming, 3.42 gears, exhaust work I am hoping I gained back my 20% drivetrain loss from the stock 260HP and 330 TQ at the flywheel. Hoping to have 260/330 at my rear wheels.....
Had a run-in with a new Charger R/T with a Hemi, supposedly a 14.5 second vehicle. Hoping my car is in that range, we were running dead even with each other on the road. :dancefool
I'd be a happy camper knowing I possibly shaved 2.0 seconds off the 1/4 mile time from a 16.5 second stock FW time......
