Engine Swap

[G-949522]

I have a 1981 Chevrolet K20 Suburban with the 5.7L engine. What is required to swap in a 454 ci engine? Will the block bolt pattern match the transmission bell housing and will the motor mounts use the same frame mounting location?
Thank you.

350 and 454 have the same transmission bolt pattern. Engine mounts on the two engines are the same. Appears to be a common swap.
