If you read the description it shows that it's been resleeved which does allow you to bore it that much.

 

Sorry to hi-jack but I am also looking at this block. I am by no means an expert with engines can anyone that really has a clue about things take a look at this and say the good and maybe the bad with this block?

 

It doesn't matter how much sleeve is done, you go that much over and you are going swimming. If you don't believe me ask any LSx speed shop the most an LS1 will bore is...3.910 most stay in the safe and do 3.905 and that's with sleeves. The MOST you can do with no sleeves on an ls1 is a clean up hone only. Now you can stroke an ls1 to anything pretty much you want, but that is a completely different process.

 

Are you saying I'd be playing with fire if I bought this block?

 

No actually water I am sure that one of those water jackets is about to give you a shower.

 

Thanks for all the advice I was really worried about this and was on the fence about buying it.

 

I beg to differ. You can clean up the stock block/sleeves to 3.905 like you said but once someone actually drops in some bigger sleeves (not exactly cheap) then you can definitely bore the cylinders to 4.030.

 

Yes and he is selling that block for 2700??...it would cost him that much for the sleeve work for a 4.030 bore, not to mention everything else he said he has put into it, and,...and he dropped the price. Now am no expert but this sounds as as right to me as a priest and a young boy walking down the street hand in hand. Hell forget what I said and who ever wants it buy it but am sure you'll end up like this guy...

a price and a deal too good to be true hmmmm?

 

I didn't say anything about whatever link was posted for sale (except that it claims it was resleeved). I'm just pointing out that you can easily resleeve an LS1 block and bore it out to 4.030" which is contrary to your last post saying it was basically impossible without having coolant issues. Would you like to see it again?

 

I agree you are 100% right, but I have yet to hear of any one doing this that was not deep into their motor. Most motors that are this much in are 1 of motors and furthermore most shops do not specialize in this type of work there are at best 4 to 5 shops nation wide i would trust to do this work on an ls1 because all that goes into this and specialized work. your talking at a minimum $10K deep motor. Oh and I was exaggerating but the sleeves alone cost about $1500+ for this type of work.

 

o2*c5 so u r telling me yo9u would not trust this motor

 

for 2700 he is just covering the cost of the sleeves and the labor to install the, we are not talking about honing, the stroke kit, we are not talking about the pistons that have to be special ordered we are not talking about a lot of things. now could he be selling something he has no idea he has yeah there is a probability, hell i have the 2700 in my acct and you don't see me running to buy this motor.

 

One of the things I noticed was he said the block was magna-fluxed.... You can't MF aluminum...... Everything else sounds plausible though I would only buy that from a builder who I knew would stand behind it.....

 

I'd just buy a 6.0 out of a junkyard for $1000 and have the stock 4.00" bore. But that's just me.

 

My LS1 block is resleaved with the old katech kit to a 4.070 and I'm running 16psi at 9.5:1 CR on pump gas. Close to 1000fwhp. I agree it could be a bomb but then again it's taken quite a bit of abuse.

 

Before you talk about how much it cost to do the work on the motor, you must know that the builder works for a machine shop and did all the labor to the block for FREE after hours work and probably had most of the parts available to him to do it. So the savings is passed on. I am the one selling it and I spoke with multiple sponsers on here and yes they did say that it is cheaper to go with a 6.0L block rather then if they were doing the work. However you can bore it out to a 4.030 with a sleeve and still be safe, no coolant issues. What I agree to with the buyer, who knows who he is, I am loosing money from what I paid for it. Not a ton, but after shipping and paypal I will be in a loss.

02*C5 what does that link have to do with my block I am selling? and why are you asking for my engine builder contact info to get your block done if you know it is not possible???? whatever

Peace

 

How many threads are you going to make about this?

I know you want it and you're waiting for someone to come along and tell you everything will be ok and you should buy it. So far all you've gotten is negative responses about it but those aren't good enough. I'll help you out.

Buy it, it's ok. I know the seller personally and he'd never do anyone wrong. He's very knowledgeable and what a deal!

There, I typed what you wanted to read. Make the purchase so we can all jerk off to your ramblings about how you got screwed. I'm looking forward to your future threads.

 

I just want to know how you magna-fluxed that block is all.

 

I am not sure I will call and ask the builder on Monday.
