Aluminum rods ? makes a difference.

Re: engines?
 
If it's running well and has good components (like premium rods) then 300 runs should be ok. Lots of variables like radical cams and RPM range but 200 runs would be the minimum you could expect to get out of it.

if the engine has good stuff in it 300 is a safe # ck the liftes at this point. throw the rods away after 600 pass

If it has steel rods then 300-400 should be fine.
