Thanks for the reply JL.

One more question for you. Is there anything to the story that the cylinder walls are "thinner" on the 03's?


Rocks

 

Yes, it is very possible. The space between the cylinder walls is in question. The extra weight was from the extra webbing and material on the outside of the block.

To the best of my Knowledge the cylinder walls are un changed.

Do you know this first hand? I know you work for Ford, but do you have some sort of hands on knowledge about this?

I guess what I am getting at is...just because someone hasn't walked up to you and said it, doesn't make it not so.


I would like to hear it from one of the fellows that are actually building the short blocks.


Rocks

 

You got mail.



Suavy

 

Back at ya....thanks for the help.

Tag your it!

 

 

That is pretty much how I felt but I got a couple of notes that I should not use the 03 block if I was going 0.020 over.

If JL has had no issues with as many engine then I wont worry.

JLP has sold a ton of em and so has a lot of other builders, everybody is using that block. The old block had relatively thin cylinder walls and to make them any thinner......well you know

Funny you should mention it. Our Mahle Motorsport forged pistons were shipped Monday and we should get them this week.

 

Ok i did he math and 354 = about 5.8 Liters. So here's my question. Are you offering this engine for sale? Or is it still in the experimental phase. How does this engine idle and sound etc. Can you street it (traction and transmission issues aside)? Im basically asking if you put it in a daily driver am i gonna hate riding around in it.

As for yout overbored built engines, how much out the door for the engine w/ heads, and your s/c of choice with a tune. Rough number is fine. Same questions as above.

 

Tim,

Any idea what the Mahles are going to/would run? Also, any ideas if they are going to have some of the noise issues that some of the other pistons do?

Thanks,

Dan

 

I think rusty has the same motor but I am not sure......
Well his name is "rusty" on the boards.......

Edit:: here is a post he made a couple of months ago......

Dale,

Do you have any first hand knowledge on the question or are you just speculating?


Am I the only one to notice that the question has yet to be answered straight up?

That may be OK for some, but I ask a straight forward question. I did not ask the history on a block that has only been in use for 10 months.

I ask if the cylinder walls where thinner than previous year blocks. A yes or no is all that is needed for a straight up answer.

An I don't know would even be straight up.

Want to know why the I don't know is a tough answer. Because when building a "race" motor, a sonic bore test is the proper way to begin. An I don't know means, I didn't do this test, so I don't know.

That's OK though, I will get my answer one way or the other and I do hope that thinner cylinder walls are not a problem. But I will still be troubled that we are being offered "Racing" short blocks that may or may not be able to take the strain of long term abuse.
