The importance of a torque plate

Wow it was that long ago I had my 440 block machined? Didn't realize it had been that long. All I've managed to do is get the main bearings, rear main seal and crank installed. But that's because I ran out of money when the inflation+gas prices hit. Maybe I'll get the pistons and rods installed if I don't get a job offer soon (means I have to move).

I'm betting the shop didn't use a torque plate since I told them it was going to be a tow engine and rarely see over 5000 rpm. Still curious though. I'm likely moving to a state closer to sea level so the 360 in the truck now might have the cojones to do the job, then what do I do with this 440 lol... hmmm
