383 build

i am building a 383, i had all the machine work done and i got a complete rotating assm. from eagle( new crank,rods, bearings, ect..)i put new billet main caps on(4bolt). i checked my clearance with plastigauge and my main cap clearance was fine plus the crank rotated freely,once i put the connecting rods on and torqued them down to 65ft lbs as noted i have proper clearance( .002 ) but the crank will not turn, i have the timing chain on and the heads are on. i put 2 bolts on the end of the crank where the flywheel bolts up and with a bar i still cant turn the crank.....please help with my next step.

Did you turn the crank a full revolution after each rod was installed?

Did you turn it over before and after you installed the cam and timing chain?

Did you turn it over before and after you installed the heads?

If you answered "NO" to any of those questions then take it back apart and start over and do each of the above as you re-assemble it.

Make sure everything still moves after EVERY step. That's how I was taught years ago and it has saved me a lot of frustration over the years.

Did you turn the cam when you installed it? Have you adjusted any of the valves yet? I mic all eagle stuff that customers bring in before I install it. I take the cranks to my crank grinder and have them turned .010 .010 to start. Seems he always has several new eagle cranks there in the box waiting for the .010 .010 turn to make sure the rod journals are true with the mains.

connecting rods on and torqued them down to 65ft lbs

Seems a little high to me for a SBC connecting rod.
