    Its for a truck engine swap but they're basically the same other than the accessory location.

    if you want the truck accessories i'll trade you for the vette ones. you'll need to do some wiring, buy the v8 mounts, get v8 truck manifolds or even better some long tubes, get your computer reflashed, a new fan or upgrade to electric fans. there is more but it shouldn't be too bad for you since the truck came with a v8 option. once you get going it's really not as bad as sounds.
