So, I got this GE block guard ....IDK ... I think I took it with some other stuff on a trade ... anyway. So I have a B18B block that I am going to rebuild most likely with Eagle rods, Wiseco pistons....something like 9-9.5:1 81.5mm , undecided on ACLvsHonda bearings, do the assembly myself, considering having the crank/rods/pistons balanced @ local machine shop, Since the head is a freshly rebuilt B16 with ITR springs and retainers(would be nice if the bottom end could do 8500 and make use of that head, hence the balancing) , JG VicX IM, and my current turbo set up (SC34/Blox/Tial/Spearco/1gDSMbov/RC550s/Walbro255/AEM FPR/etc). Wanting to see 400whp or close to it.

So anyway, I got this block guard....ands its lookin right at me all the time ... like "you know your gonna use me" . But then I think no, blockguards are the devil ... but sleeves will never be in the budget ...and some people have used them successfully, and I will be having a bore/hone done anyway....

Should I use it and call it free insurance? Easy protection? Or should I dispose of it before I start the build to keep myself from using it .... or maybe talk myself into filling it.... I could convince myself its super cheap and better than a block guard if thats the case ... what do you think

I relly dont see how it would hurt.I think some of the old shitty designs created cooling problems but the GE one i have never heard of any problems.If you decide not to use it let me know as im doing a build oddly almost 100 identical to you.I have been weighing the ACL vs Honda bearings too.

block posting, theres a diy in the tech projects

Block posting is a bad way to support stock sleeves and for your power goals you prolly won't need sleeves or block guard unless your going over 400horse. Get a good tuner or no time like the present to learn.

Oh is it? why is it "bad" is that why endyn does it? or Nascar does it? because its a "bad" thing to do? lol, I think on b-series it really isnt neccesary, but when it comes to d-series you see alot more sleeve movement causing head gasket problems, especially running high levels of boost.

So I always suggest block posting on D-series if your boosting more than 15psi, and for b-series you should be fine with stock sleeves no support until the 400hp range.

Jeff, which one do you think is better... for simplicity and efficiency, block posting - vs - block filling

Man, I just can't get into the idea of posting it. I mean its hard to see how it could help as much as a guard or filling when it makes so much less contact. Plus I don't care for the drilling through the block. I guess I like that a guard or filler can be undone if the block needed to be sleeved in the distant future.

So between filling and the guard, should I just try the guard and hope it turns out well ? Or would filling be alot better? They look like about the same result to me. If any body has any firm aruments for filling, or for the guard, or for stock sleeves alone, I would like to hear your points.

good luck un-filling your block..there's no reason why you couldn't remoce the posts and fil the holes. The post give support where support is needed. I'm pretty sure you can get good infor from theoldone.com. Jeff know's what he's talking abjout..listen to the man.

im using a blockguard i my new setup. its tig spotted into place and the block will be bored and honed and resurfaced. i know people dont like them much, but ive talked it over with some engine builders and read lots of faq's and they seem to be a good addition if done right

filling is key, stuff your sleeves with devcon like i stuff you mommas *** with my dong
