no I have not had it on a track. I have made a few mods to it.
It has the off road sportsman cam shafts
Rockwell off road light weight bucket type anti pump up lifters.
power chip-no Rev limiter.
bigger throttle body.
k@n air filter.
Increased compression ratio but not much of an increase
(twice surfacing the block and cylinder head)
shift kit in transmission(totaly remanufactured 1.5 years ago) with harder materials used in the clutch packs.
light weight performance torque converter.
in drive and gas floored the transmission shifts to second gear at 61 MPH(when the engine had a Rev limiter the engine shut down at 64 MPH in first-it it will kick down to first as long as the car's speed is under 47 MPH)
synthetic trans fluid.
Mobil one.
extrude honed intake-cylinder head-and exhaust manifold.
(did that 7 years ago)-spendy-got me to over 220 HP
and improved my torque.
wetter than water additive-20 percent antifreeze-distilled water. low temperature thermostat.
removable catalytic converter.
turbo muffler.
I had the oil pump treated with anti friction/heat coatings.
I do not remember the name of the treatment-spendy
It sounds like an old piece of farm machinery at low rpms
but sounds really cool when reved up.
I am sure I am forgetting something.
It gets really good gas mileage I got 28 mpg
coming back from riddle Oregon at 80-85 MPH(or higher for short bursts)(rather have more flashlights than a speeding ticket)
It is no super car but it is a kool old car.(I'd rather have a northstar v8)
7 years ago I had money to spend-now I have a house payment.
needs paint-head liner-weather stripping and rear shocks.(and a new rear window thanks to my gangster wanto be nephew-it got shot out with a pellet gun while my mom was using it while I worked on her van-probably replace it tomorrow)
with catalytic converter in place passes deq.
I got a ticket for going 135 MPH in it once- before all of the mods.(with 3 passengers and the air conditioning on)
680 dollar ticket 7 or 8 years ago.
still runs great on cheap 87 octane fuel thanks to it's twin swirl 4 valve hemi head design(huge valves I have the best year/model cylinder head)
GM won some sort of big award for the valve train/cylinder head layout on the quad fours(in 1987)it is called L carline port.
Quad fours do have problems-head gaskets fail about every 80,000 miles.
some people have problems with the ignition coils(no distributor)they can be defective new but I take my multi-meter with me and check them in the store.
and the coil housing is supposed to be replaced every 50,000 miles(acts as the spark plug wires)(my coil pack and housing has 80,000 miles on it)coil pack and housing costs about 110.00
I have earned extra cash working on quad fours and twin cam 16's
