The very early sc t-bird engines had very few problems. As with anything all the bugs get worked out thru the years . They are next to impossible to work on. I think they give you 6 hours to change the plugs. But they can take a pounding . If you look at for sale cars most will have 140-160,000 miles on them.I have owned some and I think they are great. Put a search in for sc t-bird and you can find the owners club, there is alot of info there
Plug change takes about 6,5 hours.. Watch out the plug wires-the hi output ignition will eat them out.It will happen unexpectedly and you wonder what the heck is happening.When the boost comes on the engine will not run well.
In had a aod SC few years ago.The trans gave up the sixth day I owned the car.
i have a regular 89 t-bird (no sc) but i had to have the head gaskets replaced on that (as well as the 89 couger lol) the transmission was just rebuilt about 9 months ago and the car is just falling apart! i think the torque converter is bad but i am not sure
\'67 coupe, wimbelton white. 331 stroker backed by a T5 and 4.56;1 9\" detroit locker. not sure the horsepower or torque but i know it\'s fun, when it\'s running.
