Modular motor installation

I am interested in this too, perhaps in a kit form. The 4.6L is readily available and the 5L version is in introduction now.

I haven't done this swap (happy with the torque of a 5.7 liter rather than the buzz of a 4.6) but I understand that the bellhousing & motormounts bolt up, so most of the adaption is splicing some kind of brainbox into your Pantera wiring to run the electronic ignition & injection. Plus some bodywork: both heads need the bellhousing ends of the casting band-sawed off to shorten them enough to clear the inner wheelwells. Even after this, the left head will need a welded pocket fabricated to contain the trimmed head. The exhaust will of course be totally custom, and the engines come with an integrated power steering pump which cannot be run dry, so when its removed, you'll need a custom idler pulley to substitute, plus a shortened serpentine belt. There are several Panteras in variour POCA chapters running this motor. A better alternative may be to add the DOHC heads to the modular SOHC 5.4 truck engine to make a much more torquey DOHC engine with more power stock.

Actually this would be a better alternative than that.

The 5.4L block is cast iron and taller than the 4.6L block.

I called one of the vendors and he did not want to sell me a kit but wanted me to bring my car to him and charge me about 16k (OUCH!) to do the swap including engine. I would prefer to do it myself and just purchase the parts over time. Decisions,decisions.

I was never going to install the 4.6 dohc motor in my pantera but when my friend offered me a 30k mile, 4.6 dohc long block for ...... lets just say around 400$ I'm now selling my Aussie motor on the stand if anyone is interested. (Its a badass motor that I dont need anymore .sigh.)
Anyway I called some vendors and the parts are there. Not sure on the pricing
1. Headers 600
2. Motor Mounts 250
3. ZF mod 250
4. SDS(I love this system) stand alone system.. around 1250-1450 when it comes out this spring.

I figure the install should cost around 3k.

After ALL that work, it won't be what you want!

My 98 cobra NA with a HCI forged shortblock 11:1 cp pistons, manley rods, file fit rings, ported heads, stock but ported heads and stock cams, spanks the pantera and gets over 20 mpg. A built short block with stock heads will run you about 3 grand and HCI guarantees them unconditionally (that means a 300 shot of NOS, turbos blowers) for a year. My pantera deserves to be as fast as my SN 95 cobra convertible or is deserves to get sold. I've been able to drive my car twice may be throee times so far and I am less that impressed but it could be tuning and carb. My un cat-ed 4.6 DOHC with hooker long tubes, hooker x pipe, and flowmasters sounds about a cool as any V8 is gonna sound. It aint buzzy thats for sure.

RW you managed to dig up a 4 year old topic.

Check this out, I just did a 4.6 swap from scratch.

And it aint a little buzz box, it got torque.

I will be doing a full article for the Poca news letter. This engine gets 25 mpg and the cost was about 7 grand including a new set of CV axles we have yet to install.
