Alex,
Thanks, I have the measurements for the height of the motor mounts and have actually fabbed them up. However, I am wondering where the front to back measurement for the motor mounts is located as this will affect where everything lines up.
I assume the 427 has a different location on the block for the motor mounts, but I'm not familiar enough with them to be sure. This would place my 393 either more forward or rearward, depending on the differences in the motor mounts (not the motor perches on the frame.) I consider this to be a fairly critical location since it controls much of the other items on the build- firewall location, shifter, transmission mount, etc.... not to mention weight bias.
Nick,
My motor mounts are the Energy suspension type with the poly pads and a 14 MM stud mount. I need to drill my motor perches for the stud location and weld the perches in place once I determine the location of the engine block. The end of block measurement should be perfect for my purposes if you can find it. I've never seen that particular measurement on the CR plans, but I will look again to see if it is there. Like much on the CR plans, you have to know the code to unravel some of the information. Now where did I put my secret decoder ring?
Thanks guys- Bob
