Anyone know the 2.8 crank bolt head size? I just picked up an '87 Gt for three hundred bucks, but the starter just engages but won't turn the motor. The car is surprisingly rust free so I'm hoping the motor will turn by hand.

I'm thinking 18 mm

It looks like a 3/4 fit, but won't turn -- I guess it is stuck.. still a good buy I think.

If you suspect the engine has been sitting for awhile, make sure you take the spark plugs out and squirt some oil in each cylinder. Allow the oil to soak in, and then try turning the engine over by hand again.

I used ATF in a couple of engines this way, and both engines freed up and eventually ran fine.

Yep, Car has been sitting for 12 years. I sprayed some PB Blaster in the spark plug holes. I will let it sit for a few days and try again, if not will probably put a crate 3.4 in it.

It may be wise to remove the O2 sensor before starting your engine. Screw a plug into the hole temporarily.
P-Blaster / ATF / Oil etc may foul the O2 and you'll wonder why the engine is running so bad. The "cat" may also get its share of contamination as well.

Godd idea but I don't think I will get this engine going, it seems quite stuck. I'm in the process of doing a 3.8sc swap in my formula and I wanted to do a 3.4 pushrod into this car but it looks like the 3.4 crate engine has been discontinued. Does anyone know any alternatives or another bolt in type swap?

Mine took a 19mm
