and put it in a 1970 Dart ? A buddy of mine keeps on telling me to do it with my spare Dart . Can get motor transmission and all electrics for about $4000.00 with the usual 90 day warranty . Do you think it is a good swap , what problems do you see if I go for it ?
 
There will not be any more 360 strokers made by MP. Everything will now be 5.7 and newer hemi's. This is the next step in our lives with Mopar, get use to it. Or buy a motor out of the junk yard. Sorry I must learn to do the same. The car we're working on now will be the last of the crate motors for us.

6.1 or 5.7? Not a bad price either way. Make sure the wiring is there and intact.

Guys with lightly modded 6.1's in 4100lb LX's are easily going low 12's. Take about 1000lbs off and do the math. 'Nuff said!

The cons are high price, added complexity and possibly limiting yourself to manual steering/brakes.

Can't wait to drive mine!
 
it's a 5.7 , wow , you're beating me to the mod . Do you have to run catalytic converters with this set up ? Manual steering is a no go for me , if can't be adapted to power I can't drive it .
Hows your coming along ?
 
Why not just buy the whole car and drive it, lol

I rebuilt a 340 this summer, came out great. Its a cold 50 degrees here yet the motor is running great. Why make life harder than it could be?

When they stop selling gasoline--if I am still living--I guess I be buying an electric car, guess a few will try to put an electric motor in their old cars. Seems like more hassle than its worth, imo

No, I won't be running cats. The car being over 25 years old is not subject to emissions testing here. You have to check the emissions requirements in your area.

You can run power steering but you'll have to convert it to rack & pinion as there's no room for a power steering box. The Alter-k-tion kit seems to be the most well though out and designed, as well as most popular but here's where a lot of the expense comes in 'cause it aint cheap! I'm running manual steering and even that barely clears.

How's mine coming? S L O W L Y !

I'm doing a lot of fabrication, making my own harness and modifying almost everything. I want it to be a modern car with a 1970 body as if Chrysler decided to make a Dart today. Obviously, you don't have to go that extreme if you don't want to.

If you want power steering then you need to go with an Alterkation set up or something similar. This will give you the room to get everything in there easily. If you want to run it as is in the car then you will need all the electronics and wiring you can get along with the cats or you will start throwing error codes without the o2 sensors. The one issue you will run in to is getting the transmission to work as they use the abs system and wheel speed sensors to work. Without them the car will not move. 5.7dart was experimenting with building his own tone wheel to get it to work and had th4e car moving under its own power but as far as I know it is not complete and tested yet. I have been kicking around the idea of using a newer jeep rear in the cuda to utilize the wheel speed sensors. From what i can tell it may be possible, the rear is slightly narrower and would need the leaf spring perches put on. Won't know for sure until I get my hands on one for a test fit. The 300 will use a sentry key system also so you will need the key and transponder ring that is in the car also.
 
From the cars I've seen, I could never justify the expense or hassle of a new Hemi swap.

The power isn't there vs. a Magnum and the expense is ridiculous. You could probably twin turbo a Magnum engine for what the hemi swap costs.

Oh I wouldn't go that far. I'm doing the swap on a paupers budget you just need to be frugal and know how to fab up most of your own stuff like mounts headers and stuff like that.
 
Just make sure the JY doesnt hack the wiring or anything essential to your swap. They hire some really bad yard apes sometimes.

I disagree............. The hemi has plenty of HP and HP to weight ratio will be great in an A body. I think I'm going to do a new srt8 hemi into this..............

OK, how much did he engine cost?

I haven't seen a hemi worth using listed for less than I have in my engine, air cleaner to pan. And that's done in the car and running 11s.

Check out this article.

Look at this hassle and $$$ for 250 wheel horsepower. LOL

I'm not saying it isn't cool or different (if you're into that) to do a new hemi swap, I just can't see spending the money when you can have a higher horsepower conventional small block for a LOT less.
 
Sounds like a lot more work than my Buddy thinks , might be a bit much for me . Thanks guys , you know the details that dreamers often forget about .

Sometimes you need to learn how to work around things. My long block was 450 bucks with a spun bearing BUT one of my friends is doing a stroker so I am sending my shortblock in as his core and taking his shortblock. 250 RWHP is laughable with a mild cam and some tuning I should have about 400-425 rwhp through manifolds and a manual trans. The 5 speed auto is the biggest PITA in the whole mix.
 
Get an intake and put carbs on it and pitch the electronic crap much easier, that is how the 392 crate mote is built.
 
Personally I'd rather big block it.Never mind the gen III Hemi, a good stroker big block will have more power and likely cost less than a Hemi swap.
