What is the purpose of the block guard? Is it to space the pistons from the valves in case of a blow out? just curious. Thanks. :confused: :alky:

if you're keeping your motor stock, there is absolutely no point in getting a block guard. if you're building your motor for higher hp applications, the issue of the block guard is still debatable, as some people say that it doesn't allow adaquate cooling and that sleeving is the way to go...

No need for a block guard, ever. The stock sleeves will not be able to hold any more pressure with one than without. Save your money and spend it on something that will actually help.

The block guard is more for preserving head gaskets than preventing sleeve failure. If you are running high boost, it is important to prevent sleeve walk which causes premature head gasket failure. Either turn down the timing, or fortify your block...

I personally don't like the idea of block posting because it creates pressure points on the sleeve.

Honestly, a good tune is better insurance than even a sleeved block. You will still blow your shit up if you act retarded.

:TU: That's why i'm running a block guard. With a lot of boost and high rpms I think the cylinders are going to move around a little.
