Does anyone know about a 305HO that was put into the 1984 Trans Ams? I am looking at buying one and the guy claims it has this in it?! I had never heard of one that's HO, but that doesn't mean they didn't make it. Any help is appreciated. Thanks.

I had an 82 T/A...... I believe the HO ones had the TBI motors and did not really run as well as the 4 brrl non-HO ones........
If memory serves me right....... NON-HO 4 brrl was 160hp, and the TBI HO motors were rated at 180hp.......

I'm humbling myself here....What does TBI stand for?

I owned an 86 Monte Carlo SS and the HO motor is pretty much the the same L69 in the Camaro/Firebird line except the exhaust system permitted it to make 190 HP/ 245 ft lb. in the F body. As I recall the 5.0 liter H.O. motor was introduced mid-year (March 1, 1983). The H.O. motor came with a higher lift and longer duration cam, dual snorkel intake system with `5.0 Liter H.O.' decal on air cleaner, specially calibrated Quadrajet carburetor, lightweight flywheel, electric cooling fan, bigger 2.75 inch exhaust and Corvette style wide mouth monolithic catalytic converter, 5.0 Liter H.O. and standard with 3.73 rear axle gear. In 1983, the L69, or 5.0 HO, was only available with a 5 speed manual transmission. If memory also serves correct the TBI 5.0 was rated at 215 HP but by far the HO would have been the preferred engine as TBI's came with auto 4 speed only and as already posted they did run better. My Monte could handle two of my cousins cars, one was an 81 Z28 and the other was an 85 Trans Am with the TBI motor.

PS: TBI = Throttle Body Injection

Thanks for the info. I read a little bit about it on Wikipedia, which doesn't cite a source, but has some of the same info that you just listed. It said the '84 5.0 HO motor was an L69 and it also came with the 350 flywheel and specially calibrated Quadrajet. The guy said it was a 4-barrel, so I don't think it's TBI. Also, it has an Auto transmission in it. I think I'm going down there tonight, so I'll let you know what else I find out. Thanks for the great info!!!

My 84 Anniversary T/A 305 HO had the functioning hood scoop, and special air cleaner that connected to the hood. Dave K.

Did you see it? Let us know.

A 1984 L69 5.0L HO car will have code G in the VIN number. It was rated at 190HP and was very quick for its day. A big improvement from the base 145/150HP carb'ed 305 and the '82-83 165/175HP CrossFire injected engine. This engine is actutally quicker than first few years of the Tuned Port Injected engine that came out in 1985. 1984 is the only year that manual and automatic trans were available with the HO engine.

On the '83-84 L69 Firebirds the standard single snorkle air cleaner and Ram Air top was retained. The L69 Camaro originally used the dual snorkel air cleaner and the Firebird got it in '85 and '86 when the Trans Am went to the flat hood.

this is infact the the correct info!! . I know for certian the heads were different, and most likely the cam was too. Both my 15th cars ( one auto, one std) had HO engines and fully functional hoods with QUADRAJETS. Also 84.5 first arrival of the now famous WS-6 package.

From Car and Driver October 1984:

"The L69-and-five-speed combination blasts to 60 mph in 7.5 seconds and doesn't quit until it's hit 138 mph. We likes this powertrain the best because it gives you a slick manual gearbox to play with."

Compared to:

"The March 1975 issue of "Road Test" magazine tested a 400 auto Trans Am. The car would only go 108 mph and took almost eighteen seconds to cover the quarter mile."

I pretty sure the heads were the same although I'm not 100% certain on the '83 and '84 L69 engines. The difference in the compression ratio was the size of the dish in the piston. I know for certain the long blocks(except for the camshaft) between the LG4 and L69 were shared starting in 1985 when the LG4 got many of the L69's goodies to boost the power to 165HP and then to 170HP in 1987.

The WS6 suspension package was around long before 1984. It came out first in 1978 on the 2nd-gens and was carried over to the 3rd-gen in 1982. It went though many changes and improvements during the 3rd-gen's lifespan. The '84 15th Aniversary cars had a special WS6 package that was different than the production '84 WS6. It included sway bars that were 2mm larger than regular WS6, different spring rates and shock valving, and the 16x8 Hi-Tech aluminum rims. Most of it carried over to 1985 as an improved WS6 but the '84 15th Ani 25mm rear bar wasn't and is very hard to find today. The biggest the rear bar got for the rest of the 3rd-gen run was 24mm.

There are also some odd deviations of the WS6 to keep production going during parts shortages. The most well known is WS7 which included everything but with rear drum brakes. This is often seen on '82 model year cars because of a big shortage of the rear disc components that year. Priority went to Recaro and CrossFire equipped cars. Another seldom seen one is WY6 which included everything but with an open rear axle.

Hey Guys,
Sorry I don't have internet at home so I had to wait to post!! I went down to look at the car and it was AWESOME! It did have the 305 HO and it also had the WS4 pakage. It said that right on the tag under the hood. Does anyone know the difference between the WS4 and WS6?

It also had the 4-barrell quadrajet with the functioning hood scoop that was cowl induction. The air cleaner cover had a round connecting port to the hood scoop but also cool air induction that come out near the driverside headlight.

4-speed automatic trans.

The guy let me drive it and told me to "go ahead and just stop, and put her to the floor" so....I did To my surprise she sat down and went

So, I was like "I thought it would break 'em loose" and he was like "let me drive"

So, we pulled over and he got in, he power braked it for about 2 seconds till it started to spin and the car spun (both tires) midway through second gear! Yea, I'm going back to buy it this week. It was AWESOME!

I also took pictures for my wife, loaded them on my computer and forgot to bring them!

I WILL have them tomorrow! Thanks for the posts guys! Great info!

[64-389]

From the sound of what you guys are saying, it sounds like this is a pretty rare car.

Another question, does it have the 700R4 or a 200metric? Thanks

[Old Goat Racer]

I bought a 1984 Z-28 in 85' with the 305 H.O. It had the hardest shifting 700R4 I've ever seen from the factory. It would "bark" second gear every time. Car felt like it had a loose (stall) converter. Top end wasn't bad either.

[Dens71TA]

WS4 is simply the RPO code for "Trans Am". The 5.0L engine will pull hard all the way to 5500RPM. The performance is very surprising for a 305 engine produced in the early '80 when everything else was normally a DOG.

It will have the 700R4 trans. The shift points are firm in the F-body calibrated version. Even my gutless wonder LG4 equipped '84 T/A breaks the tires loose on the 1-2 shift.

Here are some shots of the Car!

[Old Goat Racer]

Would there be a package deal with the conv?

[Dens71TA]

Wow, it looks pretty clean but I do see some paint bubbling and some dings. You don't see many '84s without the W62 "Aero Package" lower ground effects. It was a very popular option that year and actually became standard the next year.

[Dens71TA]

Hey, I was just looking at the interior pic. Are you sure this is a 5.0L HO car? I see a 6-grand tach and 60PSI oil gauge. The 5.0L HO cars had a 8-grand tach with a 80PSI oil gauge. What is the 8th digit in the VIN?

Ha! The convertable is my dad's car. It's the one we drove down to check this one out. I don't think it's for sale....

I'm fairly certain it's the 305 HO. All other clues lead in that direction. I think that the speedo only went up to 80, and the tach, don't remember. I think that's the speedo you can see in the pic.
