Help! rebuild snag!!
I overhauled my Romeo 4.6 and have dropped it into the truck. It was spinning fine on the engine stand but I honestly can't remember if i rotated it after i timed the cams. i'm mentioning this because now that it's in i can only rotate it about 35 below TDC to maybe 180 below TDC before it comes to hard interference.
The flex plate is engaged to the torque converter but nuts are not installed. WTF? I know I lined the timing chains up to the gear marks so I can't believe the valves are in interference but, I honesty don't know. Any ideas out there?

Check to see if you can still slide the torque convertor back and forth without the nuts installed? It shouldn't jam up against the flex plate. That may indicate the convertor isn't engage properly to the transmission's pump.

Will do Lime. I think you may be right. The torque converter will not pull out of the flex plate holes currently.
I pulled the converter forward to line up the flex plate holes with the studs before the engine and tranny were fully mated. must have rotated it subsequently. CRAP!! Better than what I was ddreading anyway; thought I had interference inside the engine.
Hope you're right.
Thanks

When Cam timing goes bad!
****!
Not tthe torque convberter. So I removed the valve and timing cover, examine the chains. Rotation stops at the same point every time. Took the chains off, pulled the cams to key at 90deg from head surface and rotate the crank. All good. My concern is: I ordered a timing kit from geek brothers and instead of two identical crank sprockets, it came with a single, double row sprocket that has timing marks at both sides- not aligned. Is that Ok? When the individual sprockets are installed do the timing marks coincide or are they offset by the fact that the bosses are reversed? Im kinda stuck here guys. Any help is appreciated. \
Im beginning to think i may have the wrong set in hand.

The timing marks on the crank sprocket are on the same tooth for both chains. The double sprocket is updated from the 2 single sprockets. With the crank keyway at 12 oclock the timing marks should be at 7
