In the words of the late great FZ

Great googly moogly! if anyone is even thinking about doing a stroker or even a freshen up, give this man a call.

this is a bad animal here and will rotate the earth.

Thanks FU for offering up this little beasty. If my 68 vette sells, we'll be talking!

Agree w Ron here. As a member of the FBI, I can tell you that these big inch monsters terrorize mere mortal street cars. We're talking low 10sec./700+chp NA cars that can run 160+ in the 1/2 mile. Now here's a motor w another 4 cubic inches. Badass and ready to install.

How long are the big CID, LT5's lasting??

xlr8nflorida

Nobody really knows because most done see a lot of mileage. Kurt and Dwights motors probably saw the most mileage.

Reason I am asking is for comparison sake. I am a die hard LT5 guy, have been since I was a kid and my dad owned ZR-1's in the 90's, hell first car I ever got to drive was a 94' torch red ZR-1. I only ask cause I have been doing alot of LS based stuff, bigger cube motors seem to be lasting for quite a few miles. LS stuff is good, no doubt, but I want an LT5 that will put some of the big cube LS guys in their place, lol. For me it is justification on price is all. I have no doubt a 445ci LT5 will shame most, lots of coin is all.

GTB/ZR-1

WOW... So wish I could get that motor. But, I'm too married these days to have that package show up @ the doorstep lol

GLWS, Frank!

George, Frank could ship it in a plain, brown wrapper!

GTB/ZR-1

Gerry- the issue would be the $22k hole in our account... lol

Paul Workman

Frankie... I'm a little cornfused (something new!). Do you have a "spare" big inch motor for sale, or is it the one out of the Admiral Blue car? (I hear the AB car was nasty-wicked.) OR...are you selling your Z with the 445?

Out curiosity what's the all in price to duplicate a product of such?

cv67

that kind of power esp from an LT5 is cheap!
A high quality LSx 400+ci can hit 15-20k easy
Dont worrry about longevity noones doing endurance runs Frank wont put together anything that would be quesitonable.

Paul Workman

Initially there was two approaches: first, an open-deck approach to big inches from the original LT5 block, engineered by Marc Haibeck, and later a closed deck approach - a cooperative effort between Pete Paladsidis, Bob Gillig, and AES.

Marc's ingenuous design approach was to weld a monolithic (Siamese'ed) cylinder section into the block to stabilize the cylinder liners maintaining the open-deck configuration.

The approach involved considerable modification to the block in order to make room for the new cylinder monolith that was then welded into the block. Steel sleeves were then pressed into the monolith to complete the open-deck architecture.

Top: LT5 block milled to accept the monolithic liner
Middle: The new monolithic cylinders piece, ready to be welded in...
Bottom: The monolith in place with the steel sleeves pressed in - maintaining the open deck architecture of the LT5.





Later, a second approach was devised (which is applicable for both above and below the 415 cid demarcation (including off-set ground cranks), With the input guidance of Pete Paladsidis and Bob Gillig, AES now machines the stock LT5 block to accept custom sleeves machined to convert the LT5 to a closed deck configuration (favored by Honda and others).

The approach does not use the monolithic cylinders approach, but instead stabilizes the sleeves by converting to a closed-deck architecture where the top of the sleeves are stabilized by a collar that fits into a groove machined into the block (deck).

The LT5 block is machined to accept the bigger liners. The liners have a ridge at the top to gain stability via the block*. Then the liners are notched to fit in the existing bore spacing. The result is a closed deck architecture that is thought to improve the block for future FI installations.

*IDK if a FI application using stock bore dimensions would require considerably less machining/expense.

The monolithic approach has been used in numbers too small perhaps to be technically or statistically significant, in spite of the impeccable design. However, Frank can speak to the practical reliability and to other such things as oil consumption, etc. (I believe he once said he had over 20k miles on it (the monolith motor) w/ no issues.

As for the closed deck design, there are several motors (in FBI land) converted using the (AES) closed deck approach with no problems relating to the block modifications, including a number of 441s and 427s.

AES's web page states $8500 for starters to do the basic short-block machining/parts (using the stock crank). Top end and head porting is not included in that price, nor is the forged steel stroker crank or big valves or rods that big inch (415 cid+) motors require.

CHEAP-FAST-RELIABLE Pick any TWO!

Sorry to poop in your sale ad Frank.
I don't have a ZR-1 anymore. I know from my long ago 402 build, $20k price tag is CHEAP!!!!!!

Paul
Has anyone checked with these guys for a big inch LT5 ?

That's dirt cheap for an LT5 big inch build. My 415 continues to soldier on, but its true, most big inch LT5s don't see a lot of miles. I think I've got about 10,000 or so miles on mine, including some track miles. The big stroke doesn't seem to harm the LT5 - although theoretically, it should.

Rkreigh

I'm not running the bigger bore or stroke but I've got 80 k miles on the LSV Lingenfelter 390 stroker and it runs like the day I bought it.

the big arm does put a bit of side loading but the rod angles aren't anything radical and you'll not wear out of grins anytime soon.

Not sure who might have the "highest mileage" on a 415 but I don't hear of them coming apart either.

The Haibeck block upgrade is the most ambitious and radical mod I've ever seen done to an LT5 and it provides an extremely rigid support for the liners and addresses the concern over the block being thin where the liners register in the block.

Frankie is passing on a true marvel of engineering and I wouldn't worry a minute about durability as this engine isn't built to be on the "ragged edge" and has great manners.

Make sure you beef up the drive train for this one. It's got a boat load of torq.
