I'm the second owner and she only has 60k on the clock. I'm trying to decide between some engine work or keeping it original. I think I'll probably get a shift kit and some 3.73s. So far has a Flowmaster American Thunder catback and 14 degrees advanced timing on 93 octane. Just needs some new leather and some steering suspension and brake work. Just going to be a fun car to drive around the shore of lake Michigan at GVSU next year and a little bit of a TLC/restoration project. A guy offered to sell me ported and polished e7 heads for 200 bucks with 600 miles but I don't know if its worth the effort.
Not worth it in my book. You'll have a gasket set and fluids on top of all that too. Plus, if they don't come with a flow sheet proving anything, you're pissing in the wind. That money could be better spent elsewhere.
