i dont think u can bore a lq4 block out that much
yea bore it .30 over...dont know how much though...l92 heads around 1,200
.030 over makes it a 6.06
ls3 bore is 4.065
Ive seen this built before but honestly cant find the site where...Im pretty sure it can be done basically bore it to a 376 and have either stock ls3 internals and what not or go forged and have it bored to 376...Just not sure if i would have to get the truck accessories for an l92 or jus use the accessories i already have.Basically need some info on if i can build an ls3 out of an lq4/9 since i already have a harness for my lq4 from nelson...
It's a .060 overbore, it's been done, anytime you hear of a 414 that's how much it's bored out, along with being stroked. Thing is the extra few inches isn't worth losing the cylinder wall thickness. Most guys build 414's because they blew up their 408's (which is a .030 overbore). Mind you the LS3 heads like the bigger bore because of issues with intake valve shrouding.
oh ok thx yall im guessing it would just be ten times easier to just get one of the ls3 engines out of a vette or camaro ss and get the harness or buy the controller kit from jegs.Also i know i would have to change the reluctor wheel over to a 24x.A good size cam and fast intake and you basically an ls3 500hp maybe...Ive been looking at those ls3's on ebay for around 5500 with next to no mileage (of course need to buy quite a bit of things to make it complete)but theyre pretty decently priced.
my bad .30 over is 370
414's are a 4.005 bore and 4.100 stroke a 418 is a 4.080 bore (opened up from the stock ls3 bore of 4.065) and 4.000 stroke, but i think a 4.060 with a 4.000 crank is still a 414 ive just heard more people running the taller stroke.Quote:

I've heard of a few oil consuming issues with some of the 427s. I believe it's due to the long stroke IIRC.Quote:

oh ok I c wut u mean pl4boy if I go with a 408 and use the l92s and a fast 102 intake should spend about the same as that stock ls3 and will hav more hp than a stock ls3 and it will cost less.sounds like a good idea.altho if Iam going to run boost would the 408 still b a good choice or would the 403 or 370? Also does ne1 know how much a forged 403 or 370 or 408 shortblock would cost built for boost? A price range.
370 will be slightly cheaper because of the crank. The 403 and 408 will be the same price. I wouldn't run the FAST 102 car intake. I mean you can, but I feel like at this level, you would be fine with the stock l92 intake.Quote:

Also does ne1 know the difference between the ly6 internals and my stock 05 lq4 internals? Is the bore and stroke the same? I know the ly6 comes with the l92 heads &intake.jus about to put the engine back 2gether and trying to get 390-400hp out of it being sum wut stock. Bout to put the engine in my 94 obs gmc and trying to get as much out of it sumwut stock wile I'm building another engine for boost for later.
Bore and stroke is the same.
alrite thx yall for the help I am now looking for another block to build.definitely going with a 370.altho since I already hav my lq4 torn apart and am looking to make 390-400hp could I use an ls6 cam and some 243s to get up around 390-400hp for now so that way I still hav some type hp wile I'm building this other block?oh and I dnt mean rear whp, jus kinda stock hp like a stock tbss.
LS6 cam is worthless.
oh ok how bout a specs cam from hke or I think every1 says to also go with patrick g cam? 243s a good choice?
Call Pat G. 243s are the best choice for a NA or nitrous 6.0. They keep the compression up and flow great.
alriite thx pl4yboy I'm definitely looking for sum 243s now and is there a link sum1 can post for me to be able to get to where they sell pat g's cams plz...also does ne1 know where I can get a complete engine gasket kit for my 2005 lq4 6.0. Having a lot of trouble finding a kit this specific. Or will the ls2 kit on summit work for me?
