My high school buddy had a '66 or '67 hard top GTO with the Tri-Power option. He also had a '69 GTO convertible with 400 HP Ram Air option. He had both these cars at the same time. Needless to say I was very jealous. I tried to do some quick research on the '66 & '67 because I can't remember off the top of my head which year he had. I do know it had the Tri-power engine though. Are you sure your '66 had the Tri-power option? According to this link, that motor option wasn't available in '66. See the link: http://www.oldride.com/library/1966_pontiac_gto.html I'm no expert, so I'm hoping this link doesn't have the correct info.
That information is inaccurate. 1966 was the last year for the Tri-Power. In 1967, multiple carburetors were banned from production cars. Click on the link below for the data on the 1966 GTO, and if you want, click on 1967 (in red near the top) for that data. The ban on multiple carburetors is mentioned there. http://myclassicgarage.com/marketplace/knowledge_base/1966-pontiac-gto Chris
When I was in Florida in 1965 I test drove a 1963 Pontiac Catalina 421 with tri power, automatic. That was smooth and fast.
Cool. Thanks Chris. I could have sworn he had a '66, but when I looked at the info I linked, I started to doubt my memory. Either way, it was a great car.
I don't know if the ban was just for the 1966 year or just for GTOs? It may have been a ban for NASCAR and not production? The 1967 Plymouth GTX Hemi I test drove had 2 four barrels. The 427 Corvette 435hp option had 3 two barrels in 1967. The 427 Fords had 2 four barrels.
You don't see the six banger Mustangs very often today. Not many of them were saved compared to 289 cars, and most of the 6 cylinder cars were converted to V8 cars. A telltale sign that a V8 has been put into a six car is the wheels on a six car will have 4 lugs while a V8 car has five. I'd rather have a real six banger car (with a manual transmission) than a fake V8 automatic car.
Multi-carb engines were banned for the 1967 model year on all GM cars except for the Corvette, in one of GM's boneheaded moves to protect the Corvette. Another boneheaded GM rule was the 400 cubic inch limit for intermediate cars until the 1970 model year. Ford was putting (a few) 427s in Fairlanes and Comets and Chrysler was happy to sell you a 426 or 440 Satellite/GTX/Road Runner/Coronet/Super Bee. Don't get me wrong, I'm a huge fan of GM cars of that era, but they could have been so much more without corporate edicts that emasculated some of the cars. The '67 Impala SS427 was intended to be available with three deuces, but the corporate ban came into effect and it was cancelled. This is the reason the Impala has the chrome pieces on the hood that are meant to represent triple carburetion.
I guess the motorheads hijacked this thread! Many Mustang V-8 clones also converted to 5 lugs and bigger brakes.
Go away you car people! I want to talk about dimes! As for the OP's question, yes it could be, there has been 65 coins struck in silver. As for if yours is, we can't tell without seeing the edge or knowing the weight.
Coins dated 1964 were struck until early 1966. It is more likely to find a 1965 dated silver coin than it is to find a 1964 dated coin on clad.
I can't find any record of 1965 dated silver dimes. I found a single 1965 Quarter struck on a 90% planchet, but nothing else. Can you tell me how many were made?

There are errors where the copper layer is missing from a clad coin. Measure the weight and test the specific gravity and compare it to another 90% silver dime.
