Hoping someone can help here...........have ran into complete dead ends on my part ........... I have a iron LSX block......this block has 10 threaded freeze/core plugs in it - 3 down each side, 2 in the front, 2 in the rear...they are all the same size and all threAded...they are not the same as a regular ls block , they appear to be either pipe thread or _an style THREAD .....ANYONE info as to where i can aquire 10 of these THANKS IN ADVANCE

 

Jegs, Summit or whever you bought the block from...

 

no luck there at all.....I got the block used, it was a general motors gmod test engine.....the testing facility totally stripped the block after completeing the dyno runs......

 

I thought they sold a plug kit for that block.

 

I don't think they came that way from GM. Could be wrong though.

Your best bet, short of actually measuring them, would likely be to contact whoever threaded them.

 

Run it by a machine shop and get them to mic it and check the thread pitch and threads per inch.
