No such thing as a 1980 roller motor. Rollers didn't come until 85 or 86. About any 302 can be converted to roller though. Looks like the pistons are 40 over, I'd say that ones about at the end of it's days if it needs to be bored again.
Good eye Jamie I missed the stamp on the pistons. If you still see some crosshatch in the bores and the crank looks good...No discolored journals/bearings no gouges or deep scratches.You may have an ok beater engine to play with there.It probably went 40 over when it was re-manned.Betcha the cranks been turned 10 or 20 under too. Pop a main bearing insert out and look at the back side of it.It should be stamped STD or 010/020...
plan for this engine was going to be a beater engine. were going to hone it out(hopefully) because it is about at its end. When i got the motor, they said it only had 10k on it since being rebuilt, but sadly the guy left the plugs out when he stored it and got a little moisture. SOOO Im going to put it back together and run(prob smoke) it until it dies. I guess we will see. The sad part is when we pulled the engine apart everything was nice and had little wear.
already the plan, plus a couple other things. Were doing all the little thing to try to save it a little
It's not a roller as the others have said. It's the lightweight 302 block used from 1980 to 82. Weighs in at 120 lbs. Thin everywhere. Don't spend a lot of money on it.
Also be careful around the 81 model year. They had the little 255 V8 that looks just like a 302. Smaller bore if I remember right. Had one in a 81 Mustang.
