Default LSX block plugs

I picked up an LSX block (#19213964) recently (2nd hand but unused) and its missing a couple of plugs from the coolant gallery on the rear of the block. I've searched everywhere imaginable around Australia to get these, or find something to do the job without success. The only option I've got so far is to buy a complete finishing kit for around the AU$400 mark, which I'd rather not do.

Does anyone know another place I could source these 2 plugs? Or alternative, the thread, size, pitch, etc. so I can have something made?



There are 10 holes this size in the coolant gallery for the block (2 on the front, 2 on the back, 3 on each side), and I'm only missing the plugs from the rear of the block.

I did. Machine shop wanted AU$95 per hour and estimated 3 hours work. That's too much money for 2 plugs...

I ve had similar problems with oem missing plugs. (easy solution is scavange from other blocks laying around) For you the easy solution is call or email big lsx builders. I d start with Kurt Urban, texas speed, lmr....if they dont have any of the plugs, one of them may have an alternative source or idea.
