I wish I knew some of those details when I saw that thing; I would have asked more about it. The owner (first and only) was there: She's the old lady checking out the engine. I seem to recall her saying it was all OG, but I wonder about that counterbalance shaft gear now. I saw her launch it from the lot. There seemed to be some pretty respectable pep in that car. Going downhill at least.
We kept meaning to get some c-shaft gears cut out of 4130, fully knowing they'd be buzzy, heinous, loud little things. I'm pretty sure we looked at sneaking a Capri V6 into it as well, but we would have had to completely revise the radiator mounts. I think my dad lost all interest in doing anything with the car about the time he bought a Saturn SL2, which says a lot about the driving experience. Nonetheless, I know where a traffic cone orange one is, that doesn't work at the moment. I have no idea if my dad would be willing to part with the stupid thing, though.
