this guy is supposedly selling his itr longblock for really cheap. i asked him by email to do a compression test and he said he would...and only 30 minutes later he emails me back saying he did a cold start compression test and he got 235-245. are these numbers good? even more concerning, does it only take 20-25 minutes to do a compression test? can you test a motor that's already out of the car (because it supposedly is)?

i have a bad feeling he could possibly be a scam...

oh yeah...the motor supposedly has only about 20,000 miles on it.
