leeY0!

ok well one day i was dogging the **** outta my car as usual. just finish racing a Z-28 on a rainy night.(i kno, not smart from the begining.) well i as soon as i made a u-turn, my car started shaking then i heard like the belts slappin the hood. good thing i was only a few blocks from home. so the next morning i turn my car on n i heard the belts slaping again then eventually the main pully fell off and the car turned off. when we replaced the main pully we couldnt slide the pin allthe way in. so when i tried starting it sounded like everything was just spinning. then my friend came over (a 240 guy) n helped replace the head gasket because it sounded like there was no pressure. when we removed the head we found water in the cylinders. when i told him abuot the pin on the main pully we thought the timing got thrown off. but when we checked the timing evrything seemed on point. now idunno where to go from here.. any help will be very much appreciated. thanks n lmk asap
