Hey guys I was wondering if you guys know if my 400M will bolt up and fit on C6 automatic. I have a 390 on the C6 right now. Will the mounts be the same???
Your C6 Tranny that you presantly have bolted up to the 390 will not bolt up to your 400M. The 400M has the same bolt pattern as the "385 series" engines, like the 429, 460. The 390 is in the "FE series".
thats right, you need to swap tranys or get your trans internals swapped into the correct trans case for the 400. the engine mounts from the 390 to the 400 are also different. cheers
