dwwv4; Do you have a Cleveland or 351M / 400M?
And if you do buy them keep an eye out inbetween the valves,
thats where they like to crack.
The 351 cleveland is a small block and the 351M / 400M are both big blocks
but most of the parts will interchange except the crank and rods.
You have to use the small block trany for the Cleveland and
the big block trany for the 351M / 400M.
The 400M makes a great torque motor for the street. Kurt
