340 block 360 crank build

OK, the reason, besides using what you have, is that back in the day, affordable strokers were not ever in kit form. Also, forged cranks were the only stroker cranks to be able to be purchased. There a lot of money over a cast, which were never available in a stroke other than stock.

So as of back in the day, this was the poor mans stroker to do and done seldom at that.

No one, and I really mean absolutely just about NO ONE thought the 360 was worth spit. Always seen as a low compression smog engine design for people moving. (Only people with brains, IMO, could see the 360's potential worth.)

So, the near no brainer took place. Use the bigger bore of the 340 and punch the crap out of it and cut down the 360 crank and re balance it with the new slugs. Often, they were a custom job. (READ BIG $$$$ for this!)

At .060 over, it is a 378. Close enuff to call it a 380 on the street. And let me tell you, Chevy children would often shy away from the whipping a MoPar motor head could put together.

I met one guy that had the brains and skills to machine the cranks rod journals down for a Chevy rod and a few more cubes. I wish I could remember that C.I.D. number. Anyway, it was nice to see a true to life 10 sec. Duster on the road back in the 70's! Let me tell you something guys, this is a do-able stroker for sure, pistons were (And maybe still) are on the shelf at KB for this.
