i have a spare ls block sitting around but the crankshaft has some knicks it in.. it will prob need to be at least ten under or whatever when it gets machined but will that make it less reliable when i use it someday? it will see some abuse when its used so just wondering.

 

are you reffering to micropolishin the bearing surfaces? No that wont decrease reliability it will increase it just make sure you get the correct size bearings for the machined crank sa they wont be the same as the stock

 

I would not use or recommend a reground Honda crank.Honda cranks are Nitrated when new.It's a surface hardening treatment that has a lot to do with the reliability of honda cranks.This treatment does not perpetrate very deep.Most of it will be ground away in a .010" regrind.It can be retreated but will then need to be lightly ground again.This will all cost alot more than finding a good used crank.You will also be limited in bearing sizing with undersizes.

 

ok well where is a good place to find a crank .. auto stores prob only sell regrinds

agreed. For the price of re-nitriding a crank you might as well just buy one that doesnt' need machining.
