I am looking at a 1991 FJ80 Landcruiser. It has 171k miles, custom bumpers 9k warn winch, and seems to be in good shape. They are asking $12,900 but I was thinking around $10k would be fair. The only problem I see is the 4.0 I6 is way underpowered. What options are there for engine swaps? If I could resonably stick a vortec v8 in there it would be a sweet rig. Are there SBC to FJ80 tranny adapters? I'd appreciate any info.
