Re: vortec 454
I would do it. It will bolt right in place, and there are people who will mod the harness for a couple hundred. Then all you need to do is drop in the proper fuel pump, and your good.
I almost got a wrecked Chevy Suburban with the 454 Vortec, but it didn't work out for me. A few simple mods, and they can become monsters vs stock. |

Re: vortec 454
A Vortec 454 will be using the OBDII engine control system whereas the '87 is OBDI. I believe all of the engine harness and a good portion of the vehicle harness will need to be changed. Plus you will need the PCM for the Vortec.
