Thanks for all the info Shawn, it has really been very helpful. The website you posted has some really good deals on the 5.3 & 6.0 engines. I also looked on the forum that AJ posted from TGO and I am have a better understanding of the costs associated with a LS1 swap. I really don't think I can afford the LS1 swap at this time but the truck engine seems more feasible. The TGO forum also made me just want to stay with my origional block & go 383 based on the power goals that I have, although, these truck engines are very appealing as well. I will do some more home work on the prices of doing the 5.3, and 6.0 swap, compared to keeping my origional block and strokinh it to 383.

Why waste your time with a 5.3 when you can get an LQ4 for $400-ish more and make 100hp more with the same mods...

You are right Mike, I am going to be looking more into it within the next two weeks, I saw a few 6.0 for the same price as the 5.3.

If you dont need the HP, 400 dollars buys a lot of mods/accessories.

Spencers car sounds tits:

An example of one member's costs when starting with the truck engine. Of course yours wont be the same but it's a good insight as majority of it will apply.

Sounded... Doesnt sound as bad ass now that the extra cubes of the 6.0 ate up the cam. Guess were gonna have to go bigger in the cam dept now, lol.

Let me know if you have an LS questions.

[shawnc16]

You can go cam only 5.3 or 6.0 and be able to obtain that 350 rwhp pretty easily. Not only will it make the power you want but, it will be more reliable and wont leak oil like EVERY single sbc does.

[TylerT/AZ28]

my sbc doesnt leak a damn thing. either does my truck

[d2harris]

Nathan this sounds sick! The cam sounds pretty aggressive, I checked out Spencer's thread, and it makes me want to go 6.0!

Thanks for posting this AJ, I looked at the numbers and I would just but a complete 6.0 with wiring harness, accessories and all becasue I woudn't know how to piece a bare block together. Buy a 4l60E, but looking at spencers build it looks like the swap wouldn't just go right into my third gen. I would also have to pay for labor as well. I am going to talk to my mechanic about going 6.0 to see if it is a feasible project financially for me.

[shawnc16]

Actually, the 6.0 can and will just bolt right in. Get adapter plates from ebay (1" setback plates 3/8" thick) They allow you to bolt your existing engine mounts to the LS block. Oh for $40...

For exhaust you can use the stock manifolds from an Fbody. Im sure there are plenty of members here with some manifolds laying around.
Buy the Fbody accessories (Balancer, waterpump, ETC)
