Lumpy the LeMans is a 1972 Pro Street Pontiac
GTO Clone. Tubbed and heavily modified. ODO says 90,000 which is not the
original cluster, and actual amounts on the restored frame/body and swapped
engine are unknown and certainly less, both under 10,000 miles. Car retains the
original clutch petal but has been changed to a TH-400 (3spd) auto with a shift
kit. Engine is a 1966 GTO 389 bored to approx 405 CI. Car has not had a dyno or
been raced recently. It generates a modest amount of power (my guess around 400
HP). Car is no slouch but the build is currently not centered around a high
trap speed. For those looking to increase power in the future the drivetrain is
ready to handle up to 700 HP without issue. For me, it has not been about
racing but about clubs, cruising, and shows. A future move has me putting the
car up for sale, I would happily sell the car to a friend, it runs wonderfully.
The frame is straight and the car can be floored in a straight line without
ever having to touch the wheel.
Some of the details of the engine include Comp
parts – rockers, hydraulic flat tappet cams, cam lift and duration is fairly
aggressive with a healthy lope (hence the name Lumpy for the idle). 670 heads,
Holley 750 vacuum secondary carb with manual choke, Torker II intake manifold. Engine
runs very nicely and is happiest a WOT.
Transmission is TH-400, 3 Spd, rollerized with numerous
upgrades to the clutch packs. 3000 K stall converter for enthusiastic launches
but still drives well down the freeway. It shifts perfectly and is prepped to
take on more power in the future. The drive shaft is from a retired race car.
Rear end is 3:90, GM 12 bold, C-clips are eliminated. Disc brakes in front,
Drum in rear, with an additional vacuum pump as the car makes very little
vacuum at idle. Lowered suspension in front, possibly from a Cadillac, Rear is
4-link with drag coil-overs. Car rides soft, with the expected sounds of a
4-link. Rear struts were recently replaced.
The car has a brake line lock, an auxiliary electric fan in
the event of idling in traffic on a hot day but the car has no overheating
issues and starts when hot without complaint. New exhaust with H-pipe, electric
cutouts and two resonators and two mufflers. The exhaust note is lovely with
cutouts closed and with them open sounds amazing. I would describe the paint,
although an awesome color as a "10 footer" or better, with several
cracks and dings in the front end, it is a driven car but the body needs no
work. It had new weather stripping, all windows and panels are in great shape
with no rust! No A/C, battery was relocated to trunk, all gauges and articles
work inside. The interior is near perfect, and retains much of the original look
of the GTO.
