my block cracked i am guessing about 2 weekends ago when i now think about the fresh antifreeze on the floor under the starter area. two weekends i made a first pass at cecil and went 10.27@132.74 then got rid of the hesitation and went from a 1.55 to a 1.48 and that pass should of been in the 10.1xS and it busted the block after the 1/8 mile. the crack started in the freezeplug area just at the starter and goes forward maybe 5". i bet it was there a couple of weeks but i could not find the cause when the engine was cold. must of went through all the way at cecil so now i have to decide on the next step and risk busting another block or get a race block ot hard block my spare 440 block halfway for strength. what did you guys run in to cracking blocks and how far is normal to push a stock one? i think this may be a 73. if anyone needs to know i can look later as i pull the proparts headers of.

I have had Mopar RB/B and Hemi blocks with cracks fix by a god machine shop, they can drill and install pins inthe crack, it is expensive, $100.00 and inch is what I remember and it has been awhile since I had one fixed Call around, BTW block filler will not seal the crack, been there done that Goodson sells some really good crack sealer, I have used it also and it flat works as long as you follow the instructions. It will need to be bake in a oven for a set period of time at or above 300 F , I think. Contact Goodson if your interested Pin it and use the sealer from Goodson

Had a stock block crack between the core plugs on the passenger side due to freezing. Machine shop used a lock-and-stitch method that worked quite well along with Blue Devil Ceramic sealer. Got an entire season out of it at the 650 HP range. If you can get access to the crack it could be done in the car, otherwise you will have to pull the motor. It is something you could do yourself with the right tools. Lock-n-stitch

I had a 440 develop a 3" horizontal crack b/t the freeze plugs on the passenger side. It did not freeze, so I guess it was a stress crack. It was a well seasoned 600 hp motor.
