NEW 4.6L Aluminum Blocks $799.00

[JimIII@JDM]

We have stock of several Ford 4.6L Aluminum blocks that will work with 2v, 3v, or 4V applications. These blocks are Ford part #3L2Z-6010-AA used in 03/04 Mach 1 and Lincoln Aviator. These blocks are similar in design to the factory 05+ production block that now retails for over $2,300 new from Ford! However you can get this block at a fraction of the cost! Team JDM is offering these while available for $799.00 each plus S&H. CALL US TODAY AT 732-780-0770

Some have said these blocks are for Naturally aspirated applications being as the Mach and Aviator were both N/A vehicles. When supercharging the Mach everyone would say keep the power level under 500 HP. So many associated the block with a limited power rating. Ford does not power rate their engine blocks, so there is no rating. What I can tell you is over the years we have used these blocks in many applications N/A, Nitrous, Supercharger, or Turbo! We have worked with other shop across the country who have produced much more than 500 HP with these blocks. With good forged internals we would rate these blocks capable of 700+HP or more. I have reports from a shop in florida who has this in a 4V application making over 700 RWHP now for a few years with our 298 rotating group!! So we do have some real world insight to these and we are confident to use these as an alternative to the 4.6L 05+ Mustang production block.

Are these still available?

What is the difference between these and the 05+ blocks?

Thanks.

I'm going to jump in here with what I know. I've used a 1L block like JDM is advertising for a build in the past. The main differences are about 5 lbs of aluminum. The 3L block used on S197's has the extra 5 lbs of weight and they are reinforced a little more with that weight. A search should turn up the answers I received when I asked the same question to the general forum a few years ago.

With that said I wasn't able to test the limits of the 1L block. I reached an actual 699rhwp (actual means uncorrected, it's what the block was feeling) with 19psi being pushed through a D1, E85, flat top pistons, and the stock crank. That was also with stock tty hardware.

It's a very strong block that will probably handle what you can throw at it. It's at least as strong as a Teksid IMO. My opinion is that the 3L is the strongest block Ford ever made for a production vehicle with the 1L and Teksid right behind.

IIRC JDM bought a lot of 10 of these a few years ago and they were brand new, only unpacked to be repacked and shipped to them.

Everything bolts right up, the knock sensor bosses are in the same place as are the motor mount points. No adapters are needed to use this block in place of a 3L.
