Default Considering building a 6.0, but am new to LS series...

OK, I am a newbie, so don't beat me up too bad if I posted in the wrong forum. Just let me know where my post should be or just guide me to the correct information. Thanks.

I haven't dealt much with small block chevys for quite some time. I have some experience with older 283, and 350ci.

I have the chance to get a 6.0 from a 2001 GMC 2500, for free. I would be interested in building this, but don't know how much different the newer engine is from the older 60-70s SBC, except for having OBD.

How much can be done with the 6.0L, is it a reliable block, can it be stroked, and what parts are interchangeable with other small blocks. Thanks for any input.

2001 & up 6.0 blocks are tough and very reliable. It can be stroked to a 402 with a 4.000" crank, 4.000" crank and bore it .030" over= 408, 4.000" crank and bore it .060" =414. Most people do the 408 if they stroke it. I'm not familar at all with older sbc, but from what people have shown me about the older sbc, the newer Gen III/IV motors are a whole lot easier to work on. Hope this gives you a little of an idea. If you can get a 2001 & up 6.0 for free, you'd better jump on it! Good Luck!

although it was an expensive build cause of top of the line parts, one of my friends had a 6.0based engine(408) that made 520rwhp on 93 octane. not bad at all for a reasonably driving car

Even if you decide not to build it you can always sell the block as long as it's still in good shape. The iron block is about 100LBS heavier than the aluminum block but it's almost indestructable. The 408's are known to make more torque than they do horsepower, which is a good thing.

I'm building a 370 cid as we speak: 4.030 bore, 6.125 rods and stock 3.622 crank
This is for a nitrous application.
Iron shortblck is between 88>92 lbs heavier than alum.
