Comments: This is my second V6-converted MGB. My earlier conversion was a red 1975 model MGB. It was built up by Bob Zimmerman from Oak Bluff Manitoba, approximately 10 years ago. Unfortunately, that car was struck in the rear and heavily damaged. After purchasing the salvage title, I swapped over its powertrain to the newer bodyshell. As testament to all the custom pieces that Bob originally fabricated, the swap was a breeze,

The Buick engine probably has more than 20k miles on it since it was originally rebuilt, and it's actually the second Buick 231 that has been mated to the MGB transmission! The earlier Buick 231 was from a 1979 model car. It was purchased from a junkyard, patched up, and used for six or seven years before a bearing started knocking. The newer engine is from 1986. The 1986 engine runs smoother, produces much better oil pressure, and revs more freely. If you're considering doing a 231 V6 engine swap, look for the later engines. You can identify them by their 20-bolt oilpans. (They went into production in 1984 or 1985.)
