Thread: Journal Adapter?

Tweet

Hello Everyone, I was wondering if anyone knew where to obtain "thick" bearings to intall a Small Journal 327 Cranckshaft in a Large Journal 350 Block. I was informed that they make these to compensate for the difference in size of both the main and rod bearings but i cannot find any!!! Any info will be greatly appreciated

Thanks

I'm 22 why may i ask?

ok, yeah there are not many "kids" my age that still work on the old cars but i wouldn't give it up for anything. it's tradition!!!

I'm like Denny I've never heard of bearings to compensate for a SJ crank in a LJ block. Then again you could fill volumes with what I haven't heard of.

I suspect you may be thinking of the thicker bearings used to destroke a 400 SB by installing a 350 crank, something that was popular several years ago.

I suspect you may either need to dig up another block or crank and rods.

Hey everyone... i just found this on the web to answer my own question but if anyone knows of another place please let me know, the site is

I figured they were available. I am running bearing spacers in my 400 block for the 350 crank. I know Grumpy Jenkins prefered the small journal 327 crank as opposed to the large journal crank due to better bearing speed in the small journal crank.

Thanks, that is good to know i never knew of anyone to use them yet. how do they work? have you had any problems? what rpms are u turning? thanks again
