anything else to think about with that swap?
thanks

As long as you are building the block, I would bolt on a LS6 intake and slide in a nice cam with some quality springs. Also the LQ4 80mm cable driven TB should bolt right up to the LS6 intake, its better than the stock LS1 75mm TB's.

thanks for the help.
i have read that the newer lq9 rods were better,stronger.
would it be worth the swap?i work at a gm dealer,so i can get them for a steal$.
i am for sure changing cam and valvetrain,need to figure on which heads to run still.
this is going into my k5 with 2.5 ton running gear and
50"+ tractor tires,so im gonna need torque and low end power,would the ls1 intake be robbing me of low end?

For a torque, I might consider putting in a TR224 cam into a 6.0, along with some quality springs.
My goal long ago was to build a LQ4:
stock bottom end
LS6 (243) heads (milled to yield 10.5-11.0:1 CR)
LS6 intake
SLP lid (use in a fbody, a nice CAI for a truck will work)
LQ4 80mm TB
TR224 cam
1218 springs
chromemoly pr's
LT headers
The above should make for a nice torque monster.

GREAT!
thanks for the help.
with the gearing ive got im really trying to shoot for between 425-450 on hp and tq numbers.and still live on pump gas.
what if there was a posibility of nitrous down the road?anything to change with the basic build up?
thanks again

Not really, just add a Walbro 255lph pump and the set up I listed should respond well to nitrous.

If you had the money, I would go with the LS6 intake, not only does it look a thousand times better, but it would probably make similar power down low with no lop off at higher rpms. then you'd have to find the answer to what kind of fuel lines to run. The swap/conversion section should have the answer to that.

my 5.3 and 6.0 truck engine manifolds are visually quite different.io cant do pics right now.sorry.
my 5.3 intake looks like the typical ls intake,rounded top,can see the runners.
my 6.0 intake is taller,more square and boxy looking????
i do want it to be more low end power,i was just thinking an intake swap could be a future upgrade,gonna have enough$$ in the build as it is.
thanks
