Factory engine swap?
I was talking with a guy at the hardware store and he asked me if I knew about Buick putting Olds V8s in Regals. He said he bought from a dealer an 86 Regal that was supposed to have a V6 and had ran the car but didn't lift the hood until he got home and it has a V8 supposedly Olds motor. I assume a 307. He said he contacted the original owner as he's the second and she said she never had any engine swaps done. I know Olds had that flap with Chevy V8s but did they ever supply Buick with 8s?

Joe, I beg to differ the Olds 403 did not go into the Trans Am until after 78. I owned a 78 TA and it had the Pontiac 400. My girl friend at the time bought a 70 TA and got the 403 Olds in it.

Both engines were available at that time period, if it had "6.6 litre" on the hood scoop, it was on Olds 403, if it said "6.6 T/A" then it was the 400 Pontiac. If your girlfriends '70 T/A had a 403 in it, it was a transplant as the 403 did not exist yet and only Pontiac engines were available in them. Unless you meant 1980.

I did mean she bought a 1979 TA (hit the 0 by accident). She bought it (or I should say Daddy) new.
I will have to look at pictures I have of my TA. I can't remember what the hood scoop said. But, I do know it was a Pontiac 400.

The following is from Wikipedia, which we all know is ALWAYS correct...

In addition, California and high altitude cars received the Olds 403 engine, which offered a slightly higher compression ratio and a more usable torque band than the Pontiac engines of 1977.
Beginning in 1978, Pontiac engineers reversed years of declining power by raising the compression ratio in the Pontiac 400 through the installation of different cylinder heads with smaller combustion chambers (1977 pontiac 400 engines also had the 350 heads bolted to the 400 blocks, these heads were known as the 6x-4 heads)(taken from the Pontiac 350). This increased power by 10% for a total of 220 during the 1978-79 model years. The 400/403 options remained available until 1979, when the 400 CID engines were only available in the 4-speed transmission Trans Ams and Formulas (the engines had actually been stockpiled from 1978, when PMD had cut production of the engine).
