Got 1978 trans am 342. Posi , super t10 , and w72 car has correct intake chrome valve covers but left factory without the shaker call outs wich I have heard of before nothing there maybe they ran out? But anyway got cheap unmolstead barn find and got her running purrs brakes fixed and only thing left is electrical dash is completely out then it's cruise or ripping tires !
Ok let me help you out with this one as well. All early 77 shakers were a "low rise, small mouth and had a sharp peak" just like the hood did. They also all said T/A 6.6 on pontiac 400 W72 cars with the "german style" lettering. Mid year 77 got the redesigned shaker that remained till 81. The myth of only olds 403 cars getting 6.6 liter decals is not accurate but is commonly believed. Between 77-78 there were 3 different types of lettering. As far as 78 cars not getting shaker decals unless they were Y88 as you show in video or Y82 s/e cars. This i have never heard of before and i am pretty sure is not a reality. Also all 79's with a pontiac 400 were left over W72 engines from 78 and were rated @ 220 hp and were backed by a borg/warner super T10 only in 79 with 3.23 rear gears. 77-78 400 cars came both with auto and 4 speed and even automatics could be ordered with 3.23 gears that were standard on all manual trans T/A's and only 400 powered cars got the 2.43 , 1.61 , 1.23, 1.00 geared Super T/10 as did earlier 74-76 455 & 400 cars.
What was said is correct. In 1978, a regular Trans Am did not receive a shaker decal if it was an L78 400 or an L80 403. Only the W72 engine came with a shaker decal this year, the T/A 6.6. However, all SE's this year received the shaker decals anyway. This also happened in 1980, there were no shaker decals unless the car was a T/A 4.9.
@@maxthe222 there was only a 4.9 in 80 or 305 for california cars. I was adding what u said. I wasnt disagreeing. So many people have misinformation and make up stuff. Ive seen brand new 77 & 78 w72 cars brand new in car and driver 1977 and the shaker says 6.6 liter and this point brought up in the magazine that its wrong but its not cause GM did whatever. Again the car was brand new
Yes you are correct! I owned a Black/Black and Gold Special Edition with T-Tops the W-72 performance package with chrome valve covers, heavy duty sway bars, 4 speed, 4 wheel disc brakes, Starlight deep dish wheels, and NO AC. It was nice... I miss it!
@@victorvondoom2386 That could be true, but I'm not entirely sure. I thought from 1977 to 1979, the W-72 only came with a 4 speed stick. The W-72 was definitely geared much lower than the standard engine/automatic Trans AM package. I don't think you could get a stick with the stock engines though. Don't quote me on either remark, I'm getting old and can't remember sh!t. I do remember it was pretty quick compared to anything else at the time. I also had a '75 Trans AM. The '75 had a great top end performance, but was a slug off the line. My '79 was polar opposite. Fast off of the line, great up to about 85mph, but not much left over 105mph. It was by far my most favorite car I ever owned.
Starting in 1977, the traditional Pontiac V8 was not used in any area that adapted California emissions standards because they couldn’t pass the stricter standards. This was mainly in California and high altitude areas. The Olds 403 was offered in place of the 400. 350 powered Pontiacs had an Olds 350 and some even had a small block Chevy 350. Everywhere else that followed federal emissions standards had Pontiac V8 availability. The Olds 403 became the standard engine in 1979 everywhere in any Trans Am or Formula equipped with an automatic transmission because Pontiac 400 production was halted after 1978. They stockpiled a number of W72 400 Pontiac engines for use in the 10th Anniversary Trans Ams and Formulas but that choice mandated a 4 speed manual until they were all used up. They never put a 4 speed behind an Olds 403.
@@bigmanblackt-shirt8506 I rebuilt a basket case 76 TA SA,, most of the parts you mentioned were missing. The only way i could confirm was PHS. Then i had to search for parts.
I never understood that. They blanked off the shaker and made it non functional starting in 1973. But the shaker used on the 1974 GTO was functional. I also believe the Formula’s Ram Air snorkel scoops could be ordered as functional through 1975.
Interesting info. I've a 1978 transam with a 400 Pontiac engine.
Nice car to drive
The 400 Pontiac was also available in 1979 - with the four speed manual only.

The 1978 4spd w72 cars got 342 rear gears one year only
@@rooster68able yes u r right. 78 4 spd got 3.42s i dont know why between 77 and 79 they made such a small change
What about the snorkel size of a 1977 W72? I’ve got a ‘77 and I’m sure of the W72, but would love the info.
Thanks for the video.
round...
It came both ways. Early 77 had the sharp lower small mouth scoop. Later 77 got the rounded regular one. Regardless of W72 or what engine it had. Fact
All L78's & W72's had the small snorkel in '77, as did the '78 L78. All 403's had the small snorkle. @@frankartale1026
Now, in 1979 they had no L-78, Right? And on these, were the L-78's auto and W-72's 4-speed?

@@victorvondoom2386 only until they ran out early in the year, from pontiac stocking back blocks from 1978. after that, no more w72.
The '77 Trans Am didn't come with the 403 Olds engine. That was the '79 Trans Am. I owned a '77 400 ci Pontiac motor.

There were 3 engines available in 1977. The information about those engines is correct in the video.
Your talking about parts of the car. The only way is to have PHS documentation.
The videos are about how to spot a fake not how to document the history of a car. But thanks for your comments.
phs cant always help you. they didnt get ALL of the documents, just most.

its too bad the shacker hood was not funtional after 1972.

Non debatable
