307 to olds 350 swap

I have an 86 cutlass with the 307 in it and I'm planning on putting a 350 out of a 73 delta 88 in it. Plan on doing a few small things to the motor, like a small cam and maybe bore it a little, but mainly want a good street car. What all will swap over from my electrical stuff to that motor?

Don't do a cam unless you are going to rebuild the entire motor. Usually the bearing go not too long after a cam swap.

Anything on the Cutlass will swap over to the 350

The 307 and 350 are externally identical. EVERYTHING swaps. If you don't have the CCC system, you're good to go. Be sure to swap the water pump, accessory brackets, and pulleys as a matched set to avoid alignment issues. Also don't forget the PS pump bracket spacers.

Super easy swap, almost everything should swap over from the 307, Just finished this swap in a 84 delta 88, you'll love it when its done
