oh, probably like 250ish. id say the block is a good 125-140 lbs. the crank is about 55 lbs, the pistons are about 8 lbs each, the rods are probably 20 lbs... then misc bolts and piston rings and wrist pins and such...
eevrything in our cars are heavy.. look at our doors, i think you can be shot at and the bullet just may get stopped. and taking them off by yourself is an easy way to break a foot.
