THE
MOUSE!
John bought the 1979 Mustang Ghia 5.0 for the sole purpose
of making the 15 minute drive to Sears Point Raceway, a
few passes down the quarter mile, and then back home.
It
was purchased in July, 1995 for $300 with 180,000 miles
on the original engine. Options included oxidized blue finish,
with rust holes in the body, and no oil pressure at idle,
but it ran. The 302-cid engine was rated at wheezing 140
hp for that year, and featured a 350 cfm 2bbl carb, C4 auto
tranny and single exhaust with cast iron headers.

"I
took it out to Sears Point on a hot November night,
the last night of the '95 season, and ran a 17.96
@ 79mph. My wife, looking on, asked "why didn't
you floor it?" I had it floored."
|
That
summer, John replaced the main bearings, shoe-shined the
crank journals with emery cloth, and replaced the oil pump
with an HV unit. The car was given a paint job... You thought
Earl Schieb was cheap? How does ten cans of Krylon White
sound? Total cost for spray
cans and a gallon of bondo: (cha ching) $46.00.
The
following season brought some significant changes. The interior
was put on a Jenny Craig diet, shedding nearly two hundred
pounds of weight., down to a featherlight 2300 pounds! The
rear wheels were fitted with 235-60R15 radials. By the end
of the '96 season the car ran a 15.95 @ 83mph, on a 2.37
60 ft.
For 1997 the weak 7.5" differential was replaced an
8.8" axle from an '86, with 3.55 gears (pleasant surprise).
Replacing the stock muffler with a turbo muffler, alone
yielded a half-second gain.
Plexiglass was used to cover the head light recesses and
front grill, areas of high drag. Along with an electric
fan to help cooling, the car was now at 14.80 @ 90.5mph,
without ever touching the engine.
The
1998 season called for some engine modifications. The stock
2 bbl. intake and carb was replaced with a Holley 600 double-pumper,
stock '85 Mustang 4bbl manifold, and '85 dual-snorkel air
cleaner. The cast iron headers were replaced with stock
late-model shorties. The single exhaust was replaced with
a homemade "sawed-off" dual exhaust. The Mouse
now scurried the quarter in under 14.20's.
Using some composite plastic material and a heat gun, John
fabricated an air dam on the nose and side skirts. The homemade
ground effects were worth nearly two tenths. A crude ram
air system, which plumbed the air inlets into the parking
lights, brought the car to a 13.96 @ 96.8mph, on a 60 ft.
of 2.064.

"I
was trying for a 13 all season, I finally managed
a 13.96 with 20 minutes left in the '98 season.
The motor was losing oil pressure with each run."
|
The following winter John retired the '79 motor and, with
help from his wife, his cousin Jimmy and his neighbor Dave,
gave the Mouse a heart transplant. An '86 roller block with
home ported E7 heads now sat in the engine bay. The entire
engine was freshened up by John in his garage, including
hand honing the cylinders, notching the pistons (the stock
'86 pistons have no valve relief's) and lapping the valves.
He deburred the block, main caps, rod caps and smoothed
the rod beams. The crank journals were polished with up
to 1500 grit wet dry paper and paint thinner. The oil passages
in the crank were chamferred.
The C4 auto transmission was replaced with an old SROD manual,
to make the trips down the track more exciting.
"My
first night at the track during the 1999 season,
I realized I had some serious traction problems
with the new setup, not to mention vicious wheel
hop. After some tinkering and tuning, a pinion
snuber, line lock, intake and header porting,
and a revised ram air setup, I managed a 13.010
@ 109.57, 2.044 to finish out the '99 season.
Plans for 2000? Get into the 12s @ 110+ mph on
street radials. I still have a few
ideas
I want to try. "
