You need a 69 or 70s block before they took the weight out and lightened the crank. Ran those blocks and cranks for years with 400 to 470 HP turninng 9000 RPM never broke a crank, block, rod or piston. Bottom ends were stock except ballanced and APR main and rod bolts. Used both stock and forged pistons.
I've got a 70 302 short block and can't get 20 bucks for the damn thing. In great shape too. Gonna scrap it soon.
Also, took the tranny apart just to be safe. The tranny guy found a broken drum & two broken stador supports. Just so y'allcan get an idea of how big the boom was.

Figured as much, better check and make sure the drive shaft isn't warped or anything. That kind of shock is felt throughout. At the shop my dad works at, there was a F-150 with a bustedcrank that came in, needed everything. tranny, rear end, and engine.
Love the paint job mang good luck with the new motor hope you build a fast one

Looks like the forging was bad. See the pattern in the last pic of the second post? that is the evidence. That was seen in a 350 stroker here not all that long ago. 4340 Eagle internal balance crank in that car (a craparo). Broke in literally the same place.
You need a 460 mang! Too much power!!!

After I got rear-ended in my Vic I used duct tape to patch a hole in my gas tank. Always carry a roll of duct tape with you, you never know when you may need it.
