Early 911 Sporto seized?

Quick rundown. '68 911 Sporto with original engine. Car is being restored and was running (poorly) about a year ago. I had a personal project which put getting this cars running issue resolved. Personal project completed and new Hardi fuel pump installed to resolve the low/intermiittant fuel issue. New pump clicking away happily. Went to start and it the motor won't turn over. Thought it was a low battery so added a jump charger and still nothing. Went back and I can't turn it over by hand.
Removed the plugs. Nothing. Pulled the starter (PITA) and still nothing. Loosened valves, still locked up. I am hoping to find a solution without having to pull the motor. Any other ideas? Is it possible for a garaged car to have rust in the cylinders in a year? The axle flanges on the Sporto spin free (axles not reinstalled yet).
Last time it was running I don't remember hearing any noises that would have hinted at an eminent problem.
Any and all ideas are appreciated. I've posted this on Pelican Parts also.
Thanks.

John,

Are you certain it has anything to do with the Sporto? Was there any opportunity for water to get into the engine? :confused:

The Sporto clutch could be stuck to the Sporto flywheel, but since you don't have your axles installed that should not cause a problem. Leaving it in a garage for a year normally I would think would not cause a problem, but high humidity, or water getting inside ( who knows how these things happen ) might be a different situation. You could adjust the valves so the intakes are open, and the exhaust are closed fill the engine with penatrating oil , let it sit for several days, drain it and then give it a try? Take a look in the carbs and make sure nothing fell inside. Also since you have the axles out of the car you can pull the engine probably in less than an hour.

The car has been garaged, carbs on, and no chance for water (outside of that which is present in the air. I rigged up a system for filling the cylinders and have had them sitting for four days. I will drain them later this week. I've come to grips with the engine removal scenario. Time will tell.
