biggdadiek, I had a early- mid 80 cutlass with a v-6 that I put a v-8 into, I kept the v6 tranny in and redrilled the bellhousing holes to match with the v8, NOT RECOMMENDED, it lasted 8 months, But both were junkyard cars so didn't matter.
The V-8 cam out of a stationwagon, can't remember what. but I think it was a malibu.
This swap wasn't too hard, but you just gotta think is it worth it to do this?
for me at the time it was, because I was told you couldn't do it without an adapter, the only reason it lasted only 8 months was that it was involved in an accident with the rear end of a semi, and that bent the frame enough to cause a problem with the torque converter which finally gave out 6 weeks after the accident. and this was with the car being driven 80 miles a day, 7 days a week for the 8 months.
