Well if the deal is right everyone would have told you to just get it anyway no matter what the details were...LOL!
It sounds like a pretty good deal as long as it actually runs. If you ride it around and it pulls real good, it doesn't actually matter if it's a stroker or big bore or whatever. As long as it runs good it's probably a good deal. Once you need to do something to the top end, you'll know for sure what's done to it and you can get the right stuff for it then.
Look at my myspace page. I have the pics of my '91 CRX with the T3/T4. I never once ran it on a dyno to confirm. I've run a stock GTO 6.0, a SRT neon stage2 mopar, and a sleeper GT cruiser built with decent results. What I'm really proud of is I built ever single part on the car. The header, entire exhaust system, all of the charge pipes, chipped and street tuned it myself... I figure based on my performance next to vehicles of known hp ratings I'm putting down right at 300 HP on a D16. Not quite 426... but certainly not the 108 stock either.
