1966 Thunderbird 390 vs 428
Hello, there! My very first time posting on this
site! I’ve been in very deeply in love with
classic cars all my short life and since a 27-
year-old with two music degrees can’t
exactly afford a Duesenberg SJ, I’ve had my
eye on Thunderbirds for a while now -
particularly the 1966 vintage. I know the Q
code 428 was an option, but a rather popular
one. My question is, which engine do you
prefer in this year and why? In my research, I
recall the extra 30 hp helps the car’s
acceleration somewhat in the 428. But what
are the pros and cons you folks find
regarding both engines and which would you
recommend for a first time classic car buyer?
Acceleration, maintenance, fuel and
additives, parts, anything that comes to
And no, it will not be my daily driver – they
will have to pry my 2010 V6 RAV4 from my
cold dead hands. ;)
Many thanks for your opinions!
How are ‘66 T-Birds worse than other classic cars?
Either engine will have enough power for cruising.
The 390 was good for a 11 second 0 to 60 and the 428 shaved off about 2 seconds. Be aware that there was also a 2 barrel version of the 390. These cars are very heavy but they make great demolition derby cars because they are so strong.
