Re: Pontiac engine in a C10

This is a rather straight forward swap. Ive done 2 Olds 455's into the trucks (a 2wd & a 4x4) which are very similar to the Pontiac. You will typically leave from the bell housing back where it is and move the frame stands to match the block. If you are using the same transmission, get the adapter plate first so you can factor that in. I prefer the thick one which moves the engine another 3/8" forward. In your case of the straight 6, the frame stands will need moved back & likely new holes drilled to match. Lorne
