You'll have to forgive me if this swap is common knowledge these days, I haven't been on here in a while and I just lost two big boxes of Mopar Actions due to water in my basement.

So here it is, what's the preferred method to shoe horn a 5.7 hemi/auto into a 1973 A-body? What's the average cost?

I think I recall that the 5.7 will not mate up to the 904, and the 518 won't fit without major surgery. Will the 5.7 trans fit, or is it Keisler to the rescue?

I'm sure they sell mounts for the swap, probably shorty style headers, too. How about the electronics? Mopar perf?

Don't tell me to do a search, this board sucks for searches. Absolutely useless. I went back ten pages and saw nothing, if there's been a recent thread that I missed please point me in the right direction.

Post pics if you've done this swap yourself. Thanks in advance.

Oh, also, MA was involved with setting up an EFI system for 318/340/360 engines through some partnership with mopar perf. Was it ever offered for sale? Pros/cons vs the 5.7 swap?

Check the site "for a bodies only" seems to be a popular topic over there. Lots of good info from guys who have or are in the process of doing this swap. With pic's & tips.

TTi makes the motor mounts and headers needed to install a 5.7L into your A-Body. And with regards to the trans, you can go to quicktime bellhousing and they sell multiple conversions. For the 5.7L it seems like they only sell connections to a Dodge Viper T56 Tranmission. I know Keisler can definitely find the right Trans set-up for you. However, with an A-Body you may have to cut out the Trans tunnel and make it larger. Just give Keisler a call.

I would assume, for the whole package, (engine, trans, wiring, headers, mounts,... etc.) it would cost somewhere around $10k+. That is if you get the engine used. If Everything is new, your looking at around $20k+. Just a rough estimate.

This guy seems to be the best guy out there for new crate engines. I have talked to him and he can also send you everything you need from headers, radiator, mounts, any Kaisler transmission, etc. I was thinking about doing a 6.1L swap into my A-Body and he said around $25k rough estimate. However, he included a Reilly Motorsports front suspension (alterktion) kit which easily costs $5k. He has already done a 6.1L swap into his 1968 Barracuda fast back:

This swap is one of those cubic dollar deals. If you are a good fabricator you can do it for less, but if not you will spend a lot more dough.

TTI probably has all you need already scoped out, but $$$$$$. You can bolt an LA trans to the 5.7 with an adapter, however not cheap. The 5.7 won't be cheap either.

My advice is to look at the costs before you decide how to proceed.


They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.

no adapter needed to bolt trans to 5.7,6.1,but you need the mp flex plate for 5.7 to 904-727,or some people just remove the ring gear off the 5.7 flywheel.

I agree %100 with you on that. However the 5.7 Hemi brings with it a few things that may/maynot be worth the $ and effort. Such as a quality aluminum head that flows well. Factory quality & reliable fuel injection, similar if not better weight. Longer stroke than a 318-340, modern effecient design, and the appeal of a Hemi. These things put out good power stock. With no weight penalty. And you have the reliabilty of a stock engine. Plus the future is bright for these engines. Lots of stuff to come.

Easy Swap:
factory crossmember, factory trans (904/727)
TTI Headers
TTI Engine Mounts
Schumacher Creative poly mounts
XV Motorsports intake/carb/ignition setup
aftermarket flexplate (Bouchillon)

To add Overdrive:
**auto**
Keisler A41 stage 1 kit, $3795 minus $150 Moparts member discount.
or Keisler A41 kit, minus trans, $1895 + you source a used 4L60E.
** manual **
RS400, 400torque, $2295 + install accys = approx $3900 minus members discount

Although it adds a lot of $ to the equation, I think going through the trouble to install one of these engines is a waste if you're going to ditch the fuel injection.

Same with keeping a 904/727 and not having an overdrive to really enjoy it.

I think that $10,000 is steep for this conversion if your doing it your self. I see 5.7 on craigs list all the time for under 1000. I did my first 5.7 swap for under 4000 and it was fuel injected with a 833 four speed trans. Mine used TTI motor mounts with LX manifolds, milodon oil pan,harness from Hotwire.com , fuel pump kit from Rock Valley to modify the stock tank and a stock 833 4 speed.

How much was the wiring harness and how did you mate up the trans? Hotwire.com, the travel place?

The new hemi has the same bolt pattern as a small block mopar with a slight difference in the crank offset. For a stick you need a special flywheel. 8 bolt crank with the right offset. I got mine from mopar performance. For an auto you need the mopar flex plate for the hemi and it comes with the right offset. I think the harness is around 1100 but there is a guy in the new products section selling them for 895 i think. No Hotwire is the name of the comopany he does custom harnesses for all different types of swaps.

Ok, cause the dot com didn't work. I suppose that 895 for EFI is the best deal going even if it is pricey.
