Are the Iron 6.0's good for .030" over? I read somewhere that .010" was the most you could bore it without having head gasket problems. Thanks for any info.

 

.010 on the aluminum block is maybe what you heard .030 is common on the 6.0s some guys have had them sonic tested and was able to go .060

 

Good, I came across a 99 lq4 for $250! I am building this up for the Wood Hauler's truck. 1 piston and cyl. was scored and the guy damaged 1 rod when disassembling it. We are going with new 4.00" crank, Wiseco forged pistons, and Scat h-beams. That's is what I need to hear. Thanks!

 

So basically you have a buildable block for $250.That'l work

That should be a serious wood hauler,sounds like the engine will be worth more than the truck.

 

.04 can be achieved easily. FYI .030 over is the standard bore for the 408 with a 4" stroke Im going 4.1" to get me a 418

 

Are you doing this on a cast iorn block or aluminum?

 

Iron block, Eagle crank, Scat h-beams, Wiseco forged pistons, and thinking about the Comp 228/230 .571/.573 on 112lsa.

Sorry, I didn't see the quote.

 

Oh yeah, for $250 i got the whole engine heads and all. Will they be fine with a mild port/polish?

 

You hav eto start out with a 6L iron truck block. The LS1 aluminum block doesnt like being bored over too much. You start running into cooling issues and good luck putting a power adder on and it living a happy life.

Rhino do a vlave job on them and call it done maybe a little cleanign up by hand would be good but not worth much more IMO. Im going with the new DART LS1 casting heads cause you can actually gain a decent amount of hp with a competition port job done on them.

250 for the block and heads is a damn steal lucky bastard it cost me 700 for my shortblock and heads shipped ot me it would have been 500 without shipping but you would still beat me.

 

i have not gone to pick it up yet, but didn't the 99's come with iron heads, and if so just rework them a little and they are good? That's easy enough. I guess I'm gonna up his pills up to 200 now!
