6.0 engine swap
6.0 engine swap well i have been saving for a cam and heads package to throw onto my ls1 and it has takin me a lil longer than i thought on picking a cam. so anyways since i just finally saved all of the money i just decided to go to a gm recycle yard to ask about a factory ws6 hood or firehawk hood and instead i left with a complete and running 6.0 motor.
so now instead of the cam right now i decided to go with a whole different motor swap. not to sure what ill be boring it to but it will either be a 427 or a 454 small block.
does anyone have any advice they could let me know about? any type of problem or any type of build advice that could maybe help my build go a lil faster and smoother? thanks everyone. maybe i can post some pics after i get it back from the machine shop.

Keep the stroker square with a 4' crank to a 408, more reliable, capable of 500rwhp and loads of trq.
Yes bigger can be done but it would have to be professionaly done to minimize oil consumption.
Custom cam of course

YOu can take it .060 over for 414" and you can put in a longer crank if you want to for even more cubes. However, anything more than a 4" crank, and the piston gets REAL short.
yea the block would be sent to my machinest and he would take care of it. so a 408 would be more reliable than say a 427?

I had the same thoughts as you did when I decided to go with the 6.0 LQ9 block. I thought the 427 was an option, but really, it's not an option with that block. As mentioned above, you can SAFELY bore it .030" over to a 4.030" bore. This is the max SAFE bore. Anything larger and it'll be too thin... You CAN bore it bigger, but you'll need to have the block sonic tested for strength as you get over 4.030" bore. With the 4.030" and a 4.000" stroke, you'll have a 408cid engine to work with.
Personally, I'm doing a 4.100" stroke for a 418cid. Mine will be a street driven daily driver for awhile though, so I don't need to rev it to the moon. The shorter strokes are better for higher revs, but will sacrafice some torque in the low and mid range. I could be wrong though....

Verdad Gallardo I did some checking around, and seems most 6.0 blocks that have been sonic tested can handle .060 over. With a .060 over on my block, i'm sitting .180 on teh thrust side, which is plenty thick.
Not is S. Fl either. My mechanic told me he could easily find me a 6.0 block out of a salvage yard for under $400. After a few weeks, I decided to find the damn block myself. Got mine for $500 shipped from Minn. I found another one too for a good price, but it was in Cal. and shipping was outrageous.
Post in a thread on this website and you'll get some hits. They are out there, just have to be patient.

but it was the whole complete motor not just the block
