A friend of mine has a complete 6.0 engine from a 99-00 2500 truck, he said it was running but had low oil pressure and would let me have it for $100. I have a 00` ss camaro with all the boltons, g5x3/114 cam and a th350 w/4000 precision industries stall. I am looking to build a fairly cheap bottom end for it and I was looking for advice on what to build using the parts I already have, also I have a spare set of 853 heads w/comp springs which I may sell and get a set of patroit performance ls6 heads, I saw they had them on special. I also need to know what to look for or address when I take the engine apart (the 6.0 engine). I would like an engine that I could turn 7000-7200 N/A because that`s where the cam really pulls, its a dog under 4 grand. Are the 6.0 cranks and rods as good as the 5.7, if so I may go that route with arp hardware through out and forged pistons ~11.5:1. Any advice welcome, thanks!

 

You want to use the ls1 crank and rods the truck stuff is weak.

 

The crank in those blocks is different from the LS1's I believe. If I remember correctly, the crank is a bit longer and thus won't mate up correctly to an LS1 tranny. I'd use LS1 rods and crank.

 

Intellegent post! considering the fact that the 6.0 is a truck motor it would and is tougher than any stock ls1. also using a stock ls1 crank and rods would not fit 346 vs. 364

 

buy that motor, if you dont i want it

i belive they are the same crank and rods in the LS1 and LQ4, just diffrent bore sizes.

look into the L92 heads, screw ported 243s

 

The cranks were only different in certain years (do a search for which ones) but I used a 6.0 crank with mine since they are a little stronger than the LS1 crank. It worked out fine for me.

 

Thanks for the replys guys keep them coming. Also can I use my asp pulley or do I need to use the truck one.

 

Wow, I have never seen a post that has such a diverse amount of Correct and incorrect things about the 99-00 6.0L.

lets say we set a few things straight...

1. Crank & Rods. Crank is diffent than a LS1, its longer at the back due to being mated to the 4L80-e in the pick ups. You "can" machein the crank down to make it work, but most will just use a LS1 crank instead. The rods are identicle to LS1 rods, therefore can be reused. To the guys that said the truck parts are weaker/stronger, you are both dead wrong. They are exactly the same in the strength department.

2. Heads are Iron, so, they make great boat anchors. You'l definately want to pickup a different set of heads.

Thank you! lol.

 

i was told all you had to do to mate it up to a 4L60E was to put the 4L60E flexplate on it.

also, i belive they heads are aluminum, i know our 2002s (317 casting) is and the 00 we looked at was aluminum also

 

I do believe the 00's are aluminum as well. I think only the 98's and previous years were iron headed.

 

1. nope, in the later years the cranks were the same as LS1s, and they just used a spacer. But the early ones were different...

2. The switch to Aluminum heads happened mid year 2000.

Good info in this thread.

So basically, an lq4 with aluminum heads (mid year 2000+) is going to have the same crank and rods, with a different bore, and lower compressions to simplify things...

I can get a 6.0 LQ4 with 317 heads that is garunteed to be good for $450. If there is anything wrong with it, he will replace it. Sound like a good deal? THis is just the LONGBLOCK.

Thinking about doing this with ported heads, a cam, rod bolts, an lifters... Im thinking it should be a nice replacement to a loose smokey LS1.

 

I nearly went the 6.0L route for my WS6 as well, the added weight of the iron block on an already porky car is what stopped me. Should be interesting none the less to see what u can pull out of it

 

I got a 2002 6.0 coming to put in my 98 Firebird with ls1 I hope the trans will fit. They said it will go right in no problems.

 

The truck crank pulley is spaced out I think 1/2" or so, as are the rest of the accessories on the trucks. If you are using your f-body accessories, you want to use your old ASP pulley.

The only truck motor that I know of that has beefier rods and pistons is the LQ9. Also, the cranks for the LQ4, LQ9, LM7, LS1, and LS6 are all the same as far as I know, except the early LQ4s as stated above.

 

It will.

 

it need to be 01 and up to fit.. i try it w/ my firebird w/ a4 it wont bolt up u need 01 and up u can tap the crank spacer out to fit

 

yes, because you cant use the intake, oil pan or accessories anyways. we are using 241 heads on ours to get a compression bump also

 

Before you get started, ask yourself if 20 more cubic inches or so is worth an extra 100 pounds on the front of your car......
