RE:STROKER Engines

To whoever thinks that big AMC engines, like 390 & 401 have bigger main 
bearings than 290 thru 360 sized engines, you are WRONG. Every single 
AMC V8 crank used in every 290 thru 401 engine size uses the exact same 
main bearings. The only difference in any AMC crank is #1, materials, 
#2, stroke, # 3 rod journal size. All [not just some] 390 & 401 engines 
use bigger ROD journals. And all, [not just some] 390 & 401 has a Forged 
Crank. All small engines[not just some] built from 290 thru 360 size has 
a Cast Crank. All [not just some] have smaller 2.09 rod journals.

When folks pass around wrong info like swapping a 360 crank in a 304 for 
more cubes, or like stating a 390 crank is hard to put in a 304 block 
because the main bearings are a different size, all it does is show 
others you do not have a clue about AMC information. All that happens is 
you confuse others that do not know either. What folks are doing with 
this wrong info is repeating something someone else stated, not the real 
facts. This type of wrong info does no one any good. Please, if you are 
confused, go get a book and learn the facts before you attempt to advise 
others or else all you are doing is spreading false information. False 
information does not help anyone.
