Hi everyone,

I'm interested in buying a '78 Trans Am with a 350 enginge. I've been
told by someone that there were no '78 Trans Ams built with 350 engines,
but the guy who's selling the car says that yes it is a Trans Am, and
yes it is the original engine.

Can anybody tell me who's right?

From what I know, there were 3.8 231 V-6, 4.9 301 Pontiac V-8, 5.7
Chevy 350? Chevy 400? Olds 403's engines avalable. Pontiac never made
late 70's 350's. Its pobably a Chevy 350. If the alternator is on the
right side of the engine with you in the drivers seat, then its a Chevy
350. IF the alternator is on top of the accesory pulleys, then its a
Pontiac 301. Still uncertain if Chevy 350s were original. There are
people here who can help you out even more.

According to the RedBook
the 350 was available in standard, espirit, and Formula. According to the
book, only the 400 and 403 was available in the TA. I do know there have been
errors in this book in the past, but it's all I've got out at the moment to
check.

They didn't come from the factory with a 350. In '78 they came with an
Olds 403 or the (better) Pontiac 400. On the shaker scoop one is called a
6.6 T/A and the other (I believe) a T/A 6.6.

The 78 with the 403 olds(which is a very good engine just ask Joe
Mondello) says 6.6 litre on the shaker and the 400 pontiac says T/A 6,6

A 1978 Trans Am did NOT come with a 350. It either had the Olds 403 or much
more desirable Pontiac 400. If he's telling you that a 350 came standard in
that T/A, he's either royally full of shit, or he just doesn't know what he's
talking about (I suspect a little of both).

TA 6.6 had 40 more hp, can tell by the decal on the scoop. TA 6.6 = 220 hp.
I know I know, big f deal, 100 less than 98 WS-6. But all the hp was corked
up w/ restrictive exhaust and intake. Let the 78 bird breathe right (headers
& intake mods) and u got some righteous muscle....

Actually, hp was only 188@4000 in '78: where the T/A excelled at was
torque: 340@1700 That's a lot of shove just barely off-idle.;-) 'Course
it needs it to launch a 4000lb (actually 3950) off the line with any
authority at all. It wasn't until '79 that the T/A went to 220 hp.
Torque went down to 320@2800. This made it more of a highway car where
its more than capable handling skills came into play. I'd put my '78
T/A against same era 'vette in the slalom any day.

Absolutely NO 78 T/A's (or any other 2nd Gen T/A, for that matter)
came with a 350 engine. That's a fact. Tell that guy that fibbing is a
nasty habit.

I have the VIN now: 2W87K8L133583, so it definitely is a '78 Trans Am, and
the original engine was a 403 olds.

Can anyone tell me how I can see if that engine is still in there, or if the
engine has been replaced? Should the 403 have '6.6' on it somewhere?

If I am not mistaken, the Olds 403 has an oil filler neck at the front of
the engine
by the intake manifold. The Pontiacs have an oil cap on the drivers side
valve cover.

No, he's right. The 78 T/A w/ high perf motor made 220 hp (T/A 6.6).
Pontiac improved the exhaust system from 77 to 78 and found 20 more
horsies. The low perf Pontiac 400 was the 180 hp torquer. (6.6 Litre).
Calif cars got the Oldsmomotor 403.

The 79 T/A 6.6 400 motors also made 220 hp and were actually 78 holdovers
that had been stored (10,000 I think). There were no low perf Pontiac 400
motors in 79. The low perf motor for 79 was the Olds 403, or the puny
Pontiac 301.

The 77 T/A high perf 400 had 200 hp due to a cam and compression increase
and the low perf 400 had 180. There weren't any Oldsmomotors in T/A's in
77 AFAIK.

That's the way I remember it anyway. I bought a 78 new back then
(220 hp 400) and have a 10th Anniversary car now (220 hp 400 4 sp).

I think that if you updated a late 70's 400 T/A w/ the latest cam profile,
fuel injection, headers and a high-flow cat and exhaust system, OD trans,
suspension and brakes to match the new F-bodies, you could show them your
tail lights.

Maybe put a machined 455 crank in a 400 with the above. Wouldn't that
be fun? Look like a stocker too.

It's just a matter of the technology that's available. Pontiac did a lot
with what was available back then. That's why the cars were so popular.

Look at the driver's side of the engine from the side of the car.

If it's an Oldsmobile, the exhaust port on the cylinder closest to the
front of the car will be to the *right* the spark plug and the exhaust
manifold will be *below* the plug.

If it's a Chevy, the exhaust port on the cylinder closest to the front
of the car will be to the *left* of the spark plug and the exhaust
manifold will be *above* the plug.

If it's a Pontiac, the exhaust port on the cylinder closest to the front
of the car will be to the *left* of the spark plug and the exhaust
manifold will be *below* the plug.

If it doesn't look like any of those, let us know.

Maybe it's a 351C! ;->

As far as I know the '77-'80 6.6 liter engine is a 200, but maybe it's
special tuned or has it a '70 345 6.6 liter engine?

For engine ID info and performance information call Mondello Performance

Actually, you could get the 400 with an auto in 78. In 79, you could
only get the 400 with the 4-speed.

Where is the oil filler hole on this engine? If it's an Olds, it will be
a spout that comes up out of the front top of the engine. If it goes into
one of the valve covers, it isn't an Olds.

that is not true, there were many P400 (pontiac 400's) put in automatics. I own
one and have seen hundreds. Mine came that way from the factory.

Sorry Charlie....the 78 had the following engine options: the 305, 350, 2
models of the 400 and the 403. Right out of the service manual as well as
the Hayne's manual....

Look to see where the fuel pump is located. If it's on the passenger side it's a chevy 350
