I bought a 400 small block thats .20 over and it was suppose to have all the rods and pistons. when i got there its missing 1 rod and piston. they didnt now what happen to them but thats not the problem. i have the numbers off the piston and i cant seem to find the piston any where. i was able to cross the # at summit but the bore size for the piston they have is 4.145. is that the correct bore size for the .20 over 400. thanks joe.
