One thing I learned the hard way about the "Blow Ties" is crankshaft thrust bearings do NOT WORK WELL on the last journal of the crankshaft.
Rotational mass in motion generating such kinetics as in a high torque, HO type, engine requires crankshaft thrust be mitigated more near a center of the rotational mass. This is especially so when it's time to lay torque on the pavement.
I threw my Chevy flywheel all throughout a pristine FoMoCo coupe I had put it in. Cheap parts & rapid response of that handgrenade engine killed my car, nearly killed me & nearly killed a guy in a car next to me. It happened on Up Shift approaching 8K. I let my clutch out it was over!
My coupe got riddled & ruined by shrapnel. I wrecked it when I lost steering as remnants of the block dropped onto the steering linkage. Next it pole vaulted over the drive shaft or transmission or both as they dropped to the road. And here for all that time growing up I thought that's what MOPAR stood for!

But even MOPAR has enough sense to place the thrust bearing in the middle of the crank, so do all the other GM Brand engines.
I run my 385 series & have for years now. I get beat from time to time as we all do. BUT I have not scattered any engines, wrecked any more cars/trucks or put innocent competitors/ friends in jeporday because I am running an explosive orange hand-grenenade of an Engine.
I've worn a few 385's out tho', but they went nobley, I drove them home to swap them when their time came. The Bottom Line is It seems I always get what I pay for.
D-Ya know where the Blow Tie Emblem came from? I heard it used to be a rectangle but when GM cot done cutting corners on it it resulted in the trapizoidal polygonic icon we all see today. Even making them FoMoCo Blue as GM did in the late 80s-& 90s didn't make the Blow Ties any better IMPO.
[in my prejudiced opinion] Hah ha!
