Jayson at MTI e-mailed us, they have three custom LS1 liners available, up to 4.25" bore! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
Thought before that that 4.125" bore with liners was the largest.. You all bore guys might want to call Jayson. He quoted $1,200 installed, good price IMO. were sponsored so not our money were playing with!
PSJ & NineBall, with a 4.25" Lunati crank = 482 cubic inches... Your opinion on that combo?
thoughts would be appreciated, as not a lot to spend on liners (4.25") @ $1,200 + Lunati crank (4.25") to get 482".
Thoughts guys?

wow

Has anyone actually run these liners in a street situation? I would be curious to see what coolant consumption and strength situations are with such a large bore.

Very interesting though!

Wow!! Let me ask this. Just how much material do you need between cylinders. I thought bore spacing was only 4.4". That would only leave .15 inch of material between cylinders. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

That would make a 454 with a 4" crank. You could put some big 2.1" intake valves in and port out a Holley intake and have a monster. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

 

umm...wow is all i can say.

Thats not a lot of $$ for a large displacement Square motor.

Jayson from MTI recommended the 4.250" set-up. He said $1,200 gets you the liners, installed, with the block surfaced. You still have to bore & hone the liners to 4.250", which obviously he can do.
As far as bore spacing is concerned, anyone (Jayson/MTI) know the spec's on that? PSJ, or NineBall?

 

Here's another question Ozzy. I'm assuming the $1200 dollars doesn't include the block. You would have to supply a block. Is that right?

Also, are they selling the resleeved block seperately without having to buy the whole motor.

This sounds interesting. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

XLR8NSS,
Yes, thet sell the block (used alloy LS1) separately, for a quoted $600!! (Cheap IMO) <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />
Or they will do yours for you. Add the cost of a bore & hone to the $1,200, & get them to do it.
And obviously, you don't need to buy a whole engine from them. This deal with 4.250" set-up is very cheap.
An 'All Bore' engine with this MTI deal works out at 411 cubic inches, for less than @$1,500, including bore/hone. Add head gaskets to that.
Thoughts on this? PSJ & NineBall?
Plus 482" with 4.25 Lunati Crank?
Cheers <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

They will be using the largest sleeves on my 434ci motor, but I am only having them take the cylinders out to 4.155" to retain a nice wall thickness for possible ~cough~ ~cough~ nitrous later. <img border="0" alt="[devil]" title="" src="graemlins/gr_devil.gif" />

They haven't built any 4.25" bore blocks yet, but their machinist thinks it will be possible with these sleeves.

As for pricing, I have no idea.

As for a HUGE motor like that, I think you will hit the law of diminishing returns once you go past a certain size. I know our intakes can't feed those cubes, so a custom intake would almost be a necessity. I told MTI that I'd rather have a badass running 434ci motor than a mediocre 471ci setup. Just my feelings on that.

Tony

 

Man,

We're going to get into the water jackets porting heads to work with that. 350cfm+ would be nice with a 454+, the problem is that someone (Wilson)needs to port that Holley intake to make sure a 350cfm set of heads is actually able to get that much cfm to the cylinders. A very large T/B would also be needed, somewhere around 100mm or so. That would be good for 700+hp N/A, then I would get concerned about the wall thickness. But then again, LPE has that 427 Twin Turbo 750hp engine that holds up.

I'd like to see a 454 street engine with a hydralic roller, that would be a great daily driver after you got it working right. GM never made a 454 Camaro, but they should have!

Bret

 

Me thinks you're gonna need some pistons to go with that too! So better add about $700 for that, and another $650 or so for rods if you want those. It's not as simple as buying a prepped block and voila, you got a big engine.

Not trying to burst you bubble, it sounds like a great deal to me!

 

I did not include pricing of rods/pistons as for anyone wanting to build a stroker/big bore engine, you would have to buy aftermarket rods and pistons anyway....
More input would be appreciated... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

Very interesting!

I'd like to see one!

Everyone already made the points I would make.

To tell you the truth, if I could get a C5R block used I would use that next time.

 

John u went at it the right way.Unless u use the C5R theres a chance of colant problems.IMO its just not worth the cash to build something that might start eating coolant.

The steel block is a great idea when building a big motor.I might do one down the road too.Then if I ever wanna spray it I can w/o worries.

I'd like a 4.25x4.25 combo... <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

Colonel is running 9s on motor with a 2-year 24,000 mile warranty. Pretty funny to think about isn't it?

Imagine that bore with a little tiny 3.05 crank for 346 ci <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> Even with a stock crank its 410. Remember back in the day when the hugest of the huge strokers weren't over what, 415?

Jayson from MTI told me that the O.D. of their biggest liners were 4.350" (outside diameter), that would go 4.200" bored out, not 4.250" as previously stated from them. Just a corrdction on their part. That still puts a stock stroke LS1 at 401 cubes (All bore motor), and a 4.25" Lunati stroker which Jayson recommends with this 4.200" bore out to 471 cubic inches.. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />
Give Jayson a call..
Cheers

 

<img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" /> Holy shheeitt.. imagine that in a vette!! That resleeve is getting more reasonable. $1200...not to bad...wow

 

Hmmmmmmm. 4.2" bore and a 4.109"stroke = 455.
SUPER DUTY!!!!!
Or 4.125" bore and a 3.25" stroke. That would still be only 347". You could probably stuff a 6.5" rod in there (2:1 rod stroke ratio) and might be able to get some serious rpm out of that. 8,500 rpm maybe???
