Not sure what happened the first time I posted this...

I just pulled my carbed 460 out to replace it with a 89 EFI 460 (got the whole truck)

I have a good 75 460 short block and a complete 89 EFI 460 that needs a rebuild. I know that the heads changed around 87 but here is my question. Can I use the 70's short block and add the top end from the 89 EFI motor? Not sure if the blocks are different or not. Thanks for the info...

The bottom end it the same, but the cam is different.
