534 YC coded Dport 455's went into 1971 GTO's.
Have owned two, & parted on three other 71 Dport 455 GTO's. Out of those was another Fremont build with a Sienna interior. The factory installed 455 Dport engine in a '71 or 72 GTO is more of an oddity than a desirable rarity. The invoice copy on this one has a few more factory installed options (PW & rally guages) than one normally sees on a 455 Dport GTO.

I bought a bunch of parts off of one about 30 years ago. It was at a tow company, I tried to buy the whole car but the company didn't want the headache associated with getting a title. It was a heavily optioned Lucerne Blue car with the 15" wheels option, had been hit in the rear. It still had the original engine in it.

Why are 71 or 72 D port engines an oddity?

I think the question would be 455 in a GTO?
The HO was probably not much more than the 455, so why not go for the extra HP? (The 455 & 455 HO were extra cost options on the GTO)

I like that castillian bronze color. I'm guessing that the d port 455 was 325 hp a step below the round port H/O 455 335 hp? It kinda makes the car unique but not as desirable

While price wise in a '71 GTO, the '71 L75 was positioned just slightly more than the standard L78 400 400 Dport engine, the factory straight line performance of the '71 & 72 L75 455 Dport GTO was not that impressive. While the low CR 455 possessed slightly more torque, a stock '71 or '72 L75 M40 GTO typically would not keep up on the street with a good shifting driver in a 400 4 spd '71 GTO w 3.55's. Many '71 & 72 L75 GTO's were bought as family transportation & quite a few even had trailer hitches added in order to pull a small runabout boat. When the HP & torque ratings were changed to NET for '72 models, the L78 400 4bbl & L75 455 4bbl were both rated @ 250 net hp (not that much difference in stock head flow between 66's & 7M5's). In the 90's, I also parted on a heavy loaded '72 Lux LeMans 455 2 door hardtop (1 of 71). That particular Lux LeMans was special ordered by the owner of a large family owned pharmacy. Over 30 option car, in my records have a buildsheet copy as well as the protect-o-plate. Also encountered & removed considerable parts from a 14 option '72 455 Lux LeMans 2 door hardtop in S Texas.

Over 30 options that combined far surpassed the cost to have ordered a Judge optioned convertible on that Lucy Blue GTO. 43, 1971 455 GTO Convertibles produced with Automatic / 0 Manual. trans. Even lower numbers for 455 HO manual (27) and auto (21) convertible cars. |
