new need help

[thatoneguy87]

hello thanks for letting me join first of all. So I have a 73 charger se that the engine has been swapped to a 360 from the 318. I'm trying to figure out if the tranny has as well I don't know how to identify what transmission is in it and the only numbers I can see on it is 10 22 and yes its an automatic. I also had a 440 cone with it and don't know if I should swap again. any info is appreciated thank you.

[Ghoste]

Hopefully the torque converter was at least changed since the 360 is externally balanced.  There should be a pad on the trans with numberss tamped into it.
Welcome to the group.

If it was a 318 car, chances are it's a 904...

And if you want to install the 440, you will need a 727 for a B/ RB block as well as new motor mounts and other misc stuff I can't remember at the moment....

[thatoneguy87]

Where would it be stamped? And the engine is a 75 so I don't even know how long ago it was changed or even if it's ran since it was. The guy before me had it since 07 and he told me it had the stock 318. But when I went to check the numbers I found out it wasn't.

 hello & welcome

On the left side of your trans along that rail just above the pan.

The easy way to tell if it is a 727 or 904 transmission is the pan shape.

[thatoneguy87]

Thanks guys I'll look tonight.

Which of course really does not matter.  All about the converter

  His question was how to tell the trans types apart and nobody gave him the easy answer. Yes. Next question is verification of the correct converter for the engine swap.

[thatoneguy87]

OK looks like i got this stamped pk3736141  4555 4152 i believe its out of a 74-75 dodge truck with the 318 or 360. If that's not right let me know. but it would make sense since my 360 that is in it is from a 74. So with that being said and it being the 727 would you stay with the 360 and build it up or throw the 440 in . the 440 is in pieces right now with a bad head. but it has been all cleaned up. And i have no idea what that is out of it is from 71. I am also wondering if there will be any troubles bolting this trans to that motor? I appreciate everything that you all have already told me. This is the reason i sign up on these forms get all the info and more from the most experienced and educated on this particular car than i could ever find anywhere else.

yes so what is the easiest way to find that out as well?

[BSB67]

I don't think he asked what tranny type.  Maybe that is what he meant.

It will not bolt to a 440.

Although other torque converters will fit, only a 360 TC will work correctly with a 360. 

[thatoneguy87]

I was asking what tranny I had and how to identify it but I'm not that educated on trans. I didn't even think about the tc . So where's the best place to get a tc? And there is no way the one from the 360 would work?

[Ghoste]

The 360 has a crankshaft (cast rather than forged) that necessitates being balanced externally.  In this case, at the tc.  To sum it up for you, if you have a 318 or 360, most came with a 904 style trans however there was a version of the 727 that was made for the smallblock and both of those are smallblocks.  No matter which style trans you have, if you have the 360 in there you need the correct style tc to work with it.  If you swap in a 440 you will need a different trans as the big block only came with a 727 and the bolt positions on the engine to mount the trans are different between the big block and small.  Also you would not want to use the 360 tc with the 440.

Ok so even with the 360 and 727 coming out of a truck  the 727 won't work with the 440?

Yep that is correct. As Ghoste stated you will need a Big Block(BB) 727 trans to go with the 440 should you decide to go that route.

Also welcome aboard

[thatoneguy87]

Ok thanks.  That sucks. So best place to get a trans?

[VegasCharger]

The best would be to go local. Craigslist, junk yard etc. You might have to be patient. Look for people selling old Mopars for parts or the whole car and offer to buy just the trans. Who knows the seller might have been sitting on the car for awhile a may decide to part out the car. Stick with a trans from a car so that you don't have a different tail shaft length such as from a truck.

Good luck

[Ghoste]

You shouldn't have too much trouble finding one if you are anywhere in North America, a widely used transmission. 

[thatoneguy87]

Ok will do. Now to the engine. I've got this 440 No idea where it came from. And it's gutted but I have all the parts I believe.  Now would you go aftermarket on everything? I've done little jobs here and there buy never deep engine work so I don't know what's best. He said they were all acid washed. And doesn't know if anything was already aftermarket. Gas had the engine apart for about 10 years.

[Ghoste]

Whats your budget?  And your expected use?

[thatoneguy87]

Whats your budget?  And your expected use?

Well as of right now I'm trying to figure that out lol. I want it to be a driver but not just a stock car. I want to be able to get into trouble with it. But i know I could probably do that with what it has in it by doing some little mods I'm sure. As of right now I'm working on reassembly. They had started taking it apart for paint . I want to get it running and drive able and figure out what it needs before that. So probably going to run what it has in it and when my wife let's me afford it, slowly build up the 440 and get the right trans. I didn't want to just jump in turn the key and try running the car after sitting so long with out being ran nor knowing if the trans was going to explode with it not being the  original engine. Now knowing the trans and engine are probably a matched set out of a truck I'm not so worried. But i am changing all the fluids and cleaning out the tank before I even think about trying to start it.

You can get a stroker kit relatively cheaply these and put together something over 500 cubes.  Do that with good heads and it'll require little else for modifications to get you into trouble.

Sounds good to me. And he said one head was cracked but I don't see it.
