Please Inform Me With Your Opinions...Again
Ok, what are the "average" compression numbers for a 12A? Im looking at an engine that is supposed to have only 87K miles on it with "compression numbers ranging from 8.3-8.7, with an average of 8.5". Is this good? The guy im buying the engine from isint actually a guy, he works for a shop, and they do have a real compression tester, well thats what he tells me anyway...So, if I buy this, he wants $450 + shipping, seem decent to you guys? Did I actually find an affordable engine that just might work for me?? It just seems too good to be true I guess...Im waiting for a response as to why it was pulled from the car.

PS - An 87K mile 1983 engine would be a nice match for my 80K mile 1983 car

I've paid as little as $50 bucks for an engine...with transmision Only reason they pulled it was the guy wanted to stuff a 350 he already had just for kicks. 'The guy' was the manager of an auto parts store who just offered it to me when i told him the model of my car to pick up a fuel filter 
hehehe....sorry....i have the feeling i'll need it soon enough... i haven't checked compression tho, so i might get a surprise

Sounds a bit much. The local yard sells long blocks for $125
Ive been to almost every junk yard around, and no one has a running 12A, and if they do, they want over $4-500 for it...If anyone can hook me up with a good cheap engine I would appreciate it...

The compression numbers are good. Mazda spec low limits are 6kg with a maximum variance of 1.5kg. I believe 8kg's is about full compression.
As to the price, it is worth whatever it is worth to you. We don't live where you do, here in Topeka, I have seen three RX's go for $10 a piece at the police impound. By the way, that was the whole car, not just the engine. I have no idea of the engine condition though.
good luck,

definitly dont contact coveys in everett, last time i asked about a 12a it was like $600+ with no warrenty.. i think 500$ for a motor would be tops for a 12a. i sold my block that had low miles for 400 and the guy came and picked it up. but i was still amzed that i got that kind of $ for it.

Wow, you guys are REALLY lucky. My local yard charges an arm and a leg for most parts. For instance, the dome light lense was $5.00!? WTF? It broke while installing, so I had to glue it back together. 
Oh well, I can't say that I haven't gotten some 'good deals' from them though.
