Unhappy timing!!!! please help!!!

I have a 1999 v-10 about 190k well she needed some head gasket, (burning coolant)

I pulled the motor out, pulled the heads off sent them out to be hot tanked and machined.

Put the motor back in, cleaned it really well painted the block powdercoated the intake manny. Made her look really pretty under the hood.

Yesterday went to do my first start up, turn the key. I got nothing... so I crawled under it left the ignition on and jumped the starter, she was cranking really weird. Turn over stop, turn over stop ect. Then she would run for about 5sec then stall out.

Is it possible that timing being off will cause this?

If the timing is off you probably have bent valves. This is not a freewheeling engine, if the timing isn't exactly right the valves and pistons become intimate and the valves lose.

Did you time the crank and cams per the Ford procedure? Did you use the special tools to align them? Without the tools there is a good chance the timing is wrong.

The way I timed it, was I put my first cylinder at tdc, put the left head on and bolted it down but left it loose incase the valves made contact. I put my timing chain on the way Ford wanted me too, then spun the motor over without spark plugs in it, the motor spun freely no resistance, then I followed the same process for the other side. The only other thing I been can figure is when I put the right head on and timed it, that the left cam might not have been at tdc. Putting it 180° out of timing. Valves weren't making contact when I had it on the engine stand with all the spark plugs out so I don't think I'm binding

I think the engine will turn freely with one cam 180° out of timing. The engine won't run, though. If you were binding you'd know it. I got mine out of time installing new guides and tensioners. I couldn't turn the engine over by hand with the plugs out of it.

I think your idea of one of the cams being 180° out is correct.

You just brought me a lot of relief, I wasn't sure if that was possible lol. This truck is my dads, I'm only 19 and this is probably one of the biggest jobs I've taken on, and he'd probably kill me if something like his valves being bent after all the money he's put into this project. Ima pull the valve covers and put the motor at tdc and see where my cams are.

Do you have the special tools to time the engine? There are two to hold the cams and one to put the crank in the proper position. If you're measuring the #1 piston position through the spark plug hole you probably can do it without this tool. I just had to buy them, PM me if you need them.
