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.
