Closed Decks

[Pete]

WoooHoooh
Closed decks are here.
391ci the easy affordable,fast way. :fahne:
Sleeves on hand no waiting.

These are very strong thick sleeves you can Turbo or Nitrous these blocks.
Also corrected some proprietary common LT5 issues that our LT5's have.
We can go up to 4.155 on these.
Looking into making some MLS gaskets for the big bore (4.155)

Pete,

That's great news!! Just in time for winter projects.:-D

Those sleeves are steel, I assume. And, no milling out the bores either!?

AND, using the stock crank, or is it also offset ground?

Gotta ballpark idea on the turn-key price?

Man! those blocks would really put some lead in the FBI's pencil at the US-41 (CPCC) drag races!! That trophy might as well take up a permanent home with us!:cheers:

391ci/390<----ford as 383 mopar the easy affordable,fast way.-----Make it "396" ;)
Sleeves on hand no waiting.-------------Cool

We can go up to 4.155 on these. --------Yes,
Looking into making some MLS gaskets for the big bore (4.155)<----old school g.m. super duty. Better numbers for bore stroke ratio and for unshrouding the valves, stock mls is 4.15 for wet liners
Congrats!
3.66x4.15 = 396

Great work Pete!
Can't wait to see the results of the first motor. No doubt it will be a screamer.

Where are these blocks coming from

They're ur block fitted w the sleeves.

[XfireZ51]

BTW, does anyone have an explanation for why GM or Lotus went w the open deck design.

Anything is possible LOL
How about offset grind crank to 3.75 and make it a 400 :)

I believe it was a fad going around the engine design community at the time. For low rate high end engines like the LT5 it allowed the complete precision finished Nikasil coated aluminum liners, pistons and rings to come as a drop in package from one supplier which in this case was the German company Mahle. Mahle was also supplying many of the other sport car engine builders including Porsche and Ferrari. I am very well aquainted with Mahle from my many years with MTU. All of the high performance marine diesels we produced had pistons from Mahle.

Thanks Phil
The first one i will keep cost down by using stock crank & rods.
Can't wait to test it in my car with my cams and heads.

Can you says 10's :dancing

Paul i have not finalized pricing yet but somewhere in the mid $13's turn key using your good stock rods and crank.

Since you already have your heads and intake ported it would be much less.

Pete

[ssrszz4]

So do you order the sleeves or send the block out to have them installed?

Thats awesome pete!..Im building closed decks over on the east coast but would love to get sleeves quicker than im getting them now....ill be calling you!!!!![emoji2] [emoji2] [emoji2] [emoji2]

Pete,

You are killing me...:cheers:

[5ABI VT]

This is great news. I see my dreams turning to reality sooner than later ! :)

[Paul Workman]

Some things ya just gotta do before ya can't...

Oh, lawdy, lawdy...here i go again!:dancing

[efnfast]

Alright, so what does this mean?
I go from 350 to 391 cubes?
Expected HP?
Cost for a build if I'm already at 530HP?

[Pete]

Paul you sure as heck can't take it with you might as well enjoy it while you can.

Steve,600-630HP is what we are looking at.
Plus all the people that have purchased products from me previously will get a 5% discount ;)

Like i mentioned to Paul on a previous post if your intake and heads are already done the price is about half for turn key.

The 944 series Porsche used an open deck design. The turbo did as well. At very high boost the cylinders move above and the head gasket loses its seal.

People started using drag racing cement and expoxy to stablize the cylinders at the base. Just enough to still allow water to flow. People have made huge power doing this old drag racing trick. 944/951/968 engines were all aluminum similar to the LT5 and is Alusil as the primary material for cylinders. Good thing the LT5 used Nikasil as it's stronger.

[alnukem]

Pete....is this a good case for chamber mods & bigger valves?

Yes sir.
The bigger bores love the bigger valves.

just a blurb I found.


"The Alusil aluminium alloy is commonly used to make linerless (https://en.wikipedia.org/wiki/Cylinder_liner) aluminium alloy engine blocks (https://en.wikipedia.org/wiki/Engine_block).Alusil, when etched, will expose a very hard silicon precipitate. The silicon surface is porous enough to hold oil (https://en.wikipedia.org/wiki/Motor_oil), and is an excellent bearing surface. BMW (https://en.wikipedia.org/wiki/BMW) switched from Nikasil (https://en.wikipedia.org/wiki/Nikasil)-coated cylinder walls to Alusil in 1996 to eliminate the corrosion problems caused through the use of petrol/gasoline containing sulfur."

The one thing they forget to mention is that only a few machine shops in the USA can properly hone or bore a block.
