i am trying to figure out if i can reuse my existing internals from my motor, it is from a marine application and if any one knows anything about a boat engine you will know that they are built to be abused. the motor is rated at 300 hp so i am trying to figure out what exactly is in it. the pistons are stamped gm 76a 10172839 and the cam has 395 wb731 and 241 97 r. i have figured out that the crank is a gm high performance cast crank and i think the rods are forged but i am not for sure see if the picture helps to identify the rods?? it seems like it has a much smoother surface then the older one... best case scenario is that i have forged rods and pistons like i was told the motor should have, worst case scenario is i use the rods anyways and get some new flat tops to throw in it.
the one on the left is the one i am reffering to, the one on the right is from a 70s small block
again its the left one
