block guards "good or bad"?

They work well. However you should have the block squared up after installing one. Such as a line bore and have a torque plate put on to check for cylinders being out of round. That's the most common problems of installing one. If someone doesn't do those machining processes while the block is apart its power you could be losing. More so on the cyln being out of round. A line bore is just a good idea for a seasoned engine when rebuilding.

liquid aluminum block guards have been done on b and d series blocks and the product used is from a company called DEVCON. my buddy did one for a guy who cracked a sleeve on a previous b16 and the guy never ended up boosting it. its a long drawn process of heating the block up after pouring this liquid epoxy" aluminum" into the deck the drilling out the holes

I never heard of the liquid aluminum block guard.
Its crazy cheaper than resleeving. If I would actually resleeve an engine god knows it wouldn't be a f series sohc.
F engines are 300 bucks, pretty cheap to just blow em up
Liquid block guard??? F that.
Block guard simply "close the deck" and when installed correctly will not warp cyln walls. Im not for using them mind you, but the damn things do work. I also prefer resleeve. An H motor that is.Last edited by MortsAccord; 05-04-2012, 01:17 AM.

Its a good alternative to sleeving. Bang for buck is a major plus. Just like stated above though get the proper machining done afterwards. Getting ready to do one on my current projectOhio CB7's Midwest CB7's Ohioaccords.com

To me, using a block guard in any "build" is no better than using a SAFC for tuning. It will work to some extent, but it strikes me as more of a halfassed way of doing things.

Originally posted by deevergote View Post$300 is cheap, yeah... but if you're adding forged internals that could get smashed if the cylinder warps, or a worked head that could get trashed if a piston should get throw into it, and the value goes up considerably. A block guard on an otherwise stock F series would be useless anyway, as the stock sleeves can withstand more boost pressure than the stock pistons can.
