DD LS

Post by ChrisH »

Why does no one run DD ls is there a reason or just because people would rather run 350s, I’m wondering to swap my 350 with a ls.

You have to drill an oil gallery into thrust bearing on any DD application, even 220/PE150 etc.

Several small things can add up to big problems.

Few things I have seen cause a short DD life. Just one of these can destroy an engine in less than 50 hours.


Wrong bearing choice

Improper clearances

Poor choice of lubrication
