Vortec motor swap

So what all is needed to make it work? I'm really not in the mood to reuse my stock block anymore. What year of motor are any of you using and what specific parts do I need to make it work? Can I at least use my current JE pistons, pending I bore it out to fit them?

An LS1 would be ideal for me, but I kinda want to keep a V6 in there.

Summary of the parts I used for a Vortec Longblock Conversion. I didn't didn't do a cheap conversion, my plan is to eventually replace the Junkyard motor with a built up Balance Shaft motor. I put in Bold what i think is require to do Vortec Longblock Conversion


  • Vortec Head Conversion
    Typically Intake Welded, Heads Redrilled, 5/16 -18 allen set screws with loctite (to plug original intake pattern), Vortec Intake Gasket.​

  • I used Ported Turbotime Vortec Heads, with the factory shaft mounted rockers and hardened pushrods.
  • New Headgasket
    I used Cometic MLS Headgaskets and ARP Headbolts, but you could use Factory Victor Reinz Heads Gaskets.​
  • 96 Up 4x4 Oil Pan
  • Oil pan gasket 10220906
  • -10AN Bung and 90 degree fitting for the turbo oil return
  • I used Turbotime braided Oil and Coolant lines.
  • I replaced the stock cam with a Turbotime 214 Custom Cam.
    To use a more agressive cam in Balance Shaft motor, you will need a different timing chain set. This is what I used
    [*]12458911 Chain Kit and new gears
    [*]89017257 Tensioner
    [*]89017259 Cover Kit.​
  • I had to replace the Oil Pan pickup because I didn't buy 4x4 motor. I had the pickup welded. I also replaced the oil pump with a Melling Select because 2003 had the new weaker casting. You shouldn't have this issue on 2002 and earlier Vortec motors.
  • I relocated my Knock sensor (I had done this previously) to my intake, but the Vortec motor that I bought didn't have the correct size for the factory Knock Sensor at the back of the intake. So you may need to deal with the Knock Sensor mounting.
  • Use the stock Flywheel and I elongated the holes on the Vortec mini starter, the stock starter could be used with elongated holes.
  • Stock water pump. Vortec Balancer, Stock Crank Pulley
  • I also used RPM transmission lines. My factory lines didn't work at all due the additional width of the Vortec 4x4 Oil Pan and I also have PEP skelton core support, which moved my radiator over 4". You might be able to bend the factory transmission lines with the radiator in the stock location.
  • I use code $59. I highly recommend some type of custom tune for this conversion. I would say this is almost a requirement.

Re: Vortec motor swap

What are my intake manifold options? Is there one for the Vortecs I can use or do I have to mod my lower manifold?

Re: Vortec motor swap

I'm assuming the rods are nearly identicle and I'm able to use my JE extreme duty pistons in the Vortec?

Rods identical to what? Make sure that the pistons are not press fit as that can limit your rods options or vice versa.
