Stock 1984 Trans Am

Post by battmann » Tue Sep 13, 2016 9:25 pm

Figured I'd start a thread about the 1984 Trans Am I bought this past February. I found it on Philadelphia Craigslist. supposed to have 80K original miles on it, but doesn't currently run. car is same color combo as mine so i should be able to use quite a bit. looks like the hatch and hood struts still work, still has the original radio and the front driver seat has power (pretty rare option). i actually have enough parts laying around that i could probably put this thing back together and drive it for awhile or sell it.

So got some great news last week regarding this car. I finally got the Pennsylvania title for it!
When I bought the car the guy had the title that was signed by the him and the guy he bought it from. I thought that was fine but when I tried to title it in my name here the DMV wouldn't let me. They said the guy I bought the car from doesn't technically own it until he titles it in his name and therefore can't sell it to me. I ended up talking to the guy in PA and he said he'd get the title in his name and send it back to me. i sent him the title and texted him every couple weeks for updates. Took forever but I'm glad it all worked out. Now I just have to go back to the DMV to get it titled in my name.
I originally bought this car for parts but it's in decent shape. I have a 305 engine from a '84 TA I parted years ago. I was hesitant to do any work on the car until the title issue was resolved. Now I think I'll install my spare engine and see if I can get it running again. The engine has been sitting for 10 years though so it may not work.
Dave - any recommendations on what to do with an engine that's been sitting? I don't want to totally rebuild it but also don't want to go through all the effort to put the engine in and it doesn't work.

Clint, it looks like its in pretty good shape.

As for the motor, pull the plugs and spray penetrating fluid in the cylinders. Let it soak for a few days and try to rotate the motor over. Spray WD40 or something like that in every couple days and rotate it the next. If it's not seized, this should clean up the cylinder walls with out breaking the rings.

Should I spray PB blaster in there or something else? Is that a penetrating oil?

PB Blaster is a quick penetrating oil. BUT it dries up quickly and things start to rust up. It will work but spray WD40 in there after it breaks free.

Got the engine ready to take out but can't get to 2 of the flywheel bolts since the engine is seized. Looks like I'll have to pull the engine with the torque converter attached. I've been spraying my spare engine with WD40 and it turns real nice but it gets to a point & then won't turn. Might have to take the engine apart to check into that. Hope it's something easily fixed & not worse like a broken rod.
Dave - how much would Tim want for his old 305??

Clint, your engine may have a rust ridge causing the stop when you crank it over. Try spraying it more and just gently force it past the stop point and then back it off again. If it stops like something is contacting a piston. Tear down will be needed.

As for Tim, I haven't heard from him in a while, but I will ask him. That reminds me, I should turn that motor over. It's been a while since I have.

Oh, and be careful pulling that motor with the convertor attached. You will need to pull it out an extra 6-8" to clear the transmission input shaft. And replace the input shaft seal regardless of how it looks. It would be a bitch if after the motor is installed and it starts leaking!

Is it easy to replace the input shaft seal? Does that require a tranny tear down?
Would it be better to take the driveshaft out and pull the tranny off the converter from underneath the car?

With the torque convertor out, the seal is right there. Pops out with a screwdriver ad taps in with a hammer.

Pulling the motor is the easier way.

Clint, I finally talked to Tim this weekend.

He said he will sell you the motor is you want it. 1988 5.oL HO, 123K, smokes on start up, but no noises. $300 or best offer.

He also wants to know if you have good front lower valance for a 83-84 Trans Am? He's thinking of grafting one to the front of the SS

Tell Tim I'll take it. It'll be easier & quicker to install something that already works.

Hey Clint, before I say anything to Tim. I just remembered this morning, that motor is a late model. The heads are different, so you will need a late model intake. Also you will need a different fly wheel and bolts. It has a 1 piece rear main seal, and the 2 piece flywheel has different mounting pattern and thread pitch.

86 to 95 parts will work.

Let me know if your still interested

So I can't use the intake & flywheel from the engine I have?
If that's the case then I'll probably look into my spare '84 engine first & then make a decision. It might be a little while until I can do that (which was the main reason I was interested in Tim's engine).

The Intake has different bolt pattern, so it won't work. Sorry, but I'd rather let you know up front before you buys something and have to buy more stuff.
