Will JB Weld do the job

I just slap a little but duct tape and baling wire on there and she'll run 10,000 RPM I guarantee it. If it doesn't hold together just call BR549.

Only one way to find out.

You must have been revving that to the limit to break it like that. Looks like it's going to have to be a forged steel crank as a replacement. Might as well upgrade while you're down there. Some forged H-beam rods and some ARP rod bolts. Put some dome top Mahle slugs in there and let her it rip. Dome ( with valve relief cuts of course ) Dome type for nitrous dish for boosted applications. If I was there I would help you put it together. I build engines better than anything I build. Give me an HP tuner suite and I'll Dial her in for you as well.

Oatmeal…leave that **** in a bowl overnight and you have to chisel it out.

what do you think.

It'll void the warranty.

Had an old 77 blazer that still ran with a crank like this.
It was knocking so I pulled it out.
I was shocked when I broke it down and found 2 cranks ... lol

Same thing for me with a 70 C10 307. Just started it when it broke.

It’s all about the prep

The 307 never was a great motor to begin with.

Elmers Glue All for the win.

Find a Vortec truck takeout motor and replace that engine. It's cheap reliable and can handle truck duty jobs.
