i may bore it to a 5.7 iron block due to the pure and simple fact of more piston choices
and the 408 idea just keeps gettin stronger - since ill already have the motor pulled and everything....

Callies, Eagle, and Lunati all make forged 3.622" stroke cranks for around $800. Once you have done this tho the cost to go to the 4" is nominal or the same.
You can use a 6.125" rod no problem just make sure your pistons are not poking out of the bore ( deck height ). I went with 6.200" rods for a compression increase of about 1:1 with flat top pistons.
Have fun with it!

Nitrous 5.3....Old thread but I think it's an overlooked option.
I have an 04 5.3 with BTR n/a stage 4 cam and titanium valve train kit. Carbed with a plate...... 10.99 @ 121 in a 4k truck. Last dyno was 560 to the wheels. Just an idea of how much a completly stock ls engine will take......I'm plan on gradually upping the shot until I hit 600 to the wheels.
