Re: 307 to 454 Motor Mounts - Clarification Needed
There only effectively two types of motor mount styles from Chevy, 307 and everything else.
Just use your 307 frame mounts, with new 307 motor mounts and you will be fine.
Return the other stuff, or get a matched set and swap them out for the original.
The block location of the motor mounts is the same between small blocks, big blocks and 4.3 V6's. All are 90 degree V's with the same bolt pattern for the mounts.
