216 Cranks

[Richard Nixon]

Hi Mike,

The journals are approx 3mm wider.

I hope to go the alloy piston route.

Thanks
Richard

OK Richard

I have some precision .030 and .040 main bearing sets that are apparently 216 but they might be post war 216 ? The brand is NASCO made here in Aust. I sent a set to Alex in Holland and I've given a few sets to other people but I've never heard back from anybody . Uptons had a large crate of these bearings and they said they were Chev bearing sets , the bearings were very cheap so I bought many sets on the chance they might be useful/ http://www.mapleleafup.net/forums/sh...ighlight=nasco

Mike, I can confirm the Nasco ones are for the early 216 crank. I have your bearings in my (1940) engine, but I haven't found the time yet to finish the shim-torque-check-remove crank again-adjust amount of shims-retorque-recheck-dance .
Still very happy with your bearings!

Richard, indeed later 216's used a different crank....I am sure it has come up on the forum a few times, so it wouldn't hurt to use the search funtion. I also seem to remember there were some comments on using the later crank in an early block.....maybe by Maurice(?).

Many thanks chaps, I'll have a read of your link Mike and do a search as Alex suggests.

hi Richard

The 216 was in production from at least 1937 to around 51 . During its long production GM made changes to the 216, so be aware of the different parts that will not swap over from earlier engines.

Theres too many variables with the '51 crank so Im getting the '41 crank reground.

This means I have a '51 engine stripped down that I no longer need and will put it up for sale.

I have sourced con rods to take shell insert bearings (Thanks Pete) in the UK and have a source for the rest, from the states.
