i have a 6.0L iron block that i had bored and linehoned now when they linehoned the block i was told that i would need a linehone timing chain cause a bearing had been spun in it at one time the motor is now a 408 stroker will the line hone make a diff what is the good and bad of it if any?



ps.i plan to spray the **** out of this motor

 

If it had a spun main bearing, throw it away and get another block. It costs more to fix it. Never heard of a line hone timing chain.

 

You can buy an offset timing chain for SBC's, but that is only needed when the block is severely warped. The older blocks would have that happen more frequently with age and overheating. Technology has come a long way, and I've never heard of anyone having a problem with the Gen III motors. I wouldn't worry about it unless you have a new chain with lots of slack in it.

 

I agree if a main spun get a new block from SPDC they are approximately 700. Will be cheaper in the long run.
