stock oil pump is fine, if you have a 04+ truck it most likely has the ls2 rotating assembly in it so pistons and rods are not needed. get a Trick or KB racing manifold, bolt on a china 80 or borg warner s475-80 and it will make 700hp to the tire

pac1218 springs, stock heads, single walbro 400 in tank pump (130 shipped with install kit)
small cam from isky, trickflow, LJMS will work fine

sub 200 dollar intercooler kit with 3 inch piping will work

stock timing chain etc.

full manual valvebody isnt needed, the stock computer can shift the trans very very well. plus you would need to install a gated shifter to get the best out of a manual valve body imo.

X2 on what Denmah said. I would also add LS9 headgaskets and Ebay headstuds just for reassurance. On my setup I went overkill and bought BTR dual spring kit but thats cause their products are bad *** for the price. I also bought the Trunion Upgrade just for added safety but some have done very well without it.

stock 5.3 head gaskets even paper ones work fine, also stock head bolts work fine, dont even take the motor apart, just a mild cam and springs is all you would need for 700

This. Bolt on a 475 and be done. 700hp is not much.

really? so thats not bad at all then. everything ive researched pointed me towards big money for this project. i know it wont be cheap but i figured itd be more than its sounding. but thanks for the help everyone. ill get a new build list together tonight/tomorrow and see what you all think

okay guys the motor im getting is going to be a pre 04 so that means rods and pistons im assuming? i almost want to do them anyways just for the extra piece of mind. but who should i get injectors from? and how many lbs/hr? im going to pick the motor up this weekend and planning on gathering parts and building the motor then buying the truck and swapping it in and then using the motor out of the truck to build for something else.

Personally I wouldn't invest the money. Throw the motor you have now in stock. Get everything made and mocked up. Then run it around 600hp until you find another gen4 (2005+) motor.

You'll have more fun, less down time, and less invested total.

why do you say this? whats so bad about the gen3? im kinda new to the ls world lol

Gen3 piston and rod on right... Gen4 on left...

Many have issues with the gen3 rods around 600ish hp. Chassis weight has alot to do with it as well.

For only 700hp I would throw any stock LS/LQ in it untouched.

I would honestly use what you have now, get it running and tuned and enjoy it. If it blows, get a gen 4 or even just buy gen 4 rods/pistons (if your block isn't trashed) and swap it.

Chances are, you'll get plenty of quality time with a smile on your face when your gen 3 as long as your tune is good and you can manage the torque properly.
