    running boards, nerf bars, step bars !!!

    Nfab doesn't stock them, but they're available for squarebodies. They're just made to order after you've made the purchase. Very happy with mine.

    CA legal LS swap

    Sadly, I'm selling the Suburban. Needed a diesel truck for all the towing I do and can't afford to have both vehicles. https://bringatrailer.com/listing/1991-gmc-suburban-4/

    CA legal LS swap

    To disable VATs, turn on electric fan controllers, etc you either need a laptop and a program like HP Tuners, or you can just pay a shop to program your PCM for you. If you're only programming one vehicle, one time, it's much cheaper to pay a shop to do the programming. In your state I imagine...

    CA legal LS swap

    I did the procedure using HP tuners. It was extremely vague. When you choose the process in their software, it tells you what to do ... Start the motor, increase revs over 2-3 second until the engine hits fuel cut off, then release the throttle and turn the engine off You don't get any...

    Those are pretty slick switches. The one I used is identical to your last photo, except not labeled

    CA legal LS swap

    The guy that programed my PCM initially disabled the PRNDL switch which you have pictured above. Turns out having that disabled prevents you from being able to do a crank relearn!! I was fighting my engine swap for a couple of months trying to figure out why I was getting false misfires...

    CA legal LS swap

    Just used a momentary switch. For those looking to do this, Tow/haul needs to be turned on using HP tuners. If my memory serves me, it's actually called tranny performance mode in HP tuners. Then you'll need to run a wire inside the cab from your PCM (pin Blue-71) to a momentary switch. The...

    Good for you. I like that stuff too. Now do me a favor and don't post here unless you have something constructive to say that's related to this thread.

    CA legal LS swap

    PART III: CAN YOU CHANGE YOUR PCM? In my research for my swap the most misinformation I read was about PCM changes. The most recent info I found on CA legal swaps was from someone who had gotten their LS swap approved within the last 2 years. They said that absolutely no changes could be made...

    CA legal LS swap

    PART II: CA BUREAU OF AUTOMOTIVE REPAIR GUIDELINES, REFEREES, AND THE PROCESS My first swap went to the referee in about 2018. It was a 3 hour in person inspection. It was not a smooth experience and at the end of it I swore I'd never swap another vehicle that needed to go through the...

    CA legal LS swap

    Beyond that, you'll need to install the rest of the EVAP system with your donor engine. This includes the purge valve (located on top of the intake manifold), vapor canister (large black plastic box located beside the gas tank) and vapor vent valve (located beside the vapor canister). For my...

    CA legal LS swap

    There is SO MUCH misinformation out there on doing a CA legal swap! I've now done two. My first was a 3RZ swap in a Toyota. The second was a LQ4 swap into my V2500 Suburban. I thought I'd post some details of the swap while it is still fresh in my mind. This is by no means a replacement for...

    LS Swap and the CA DMV

    You're smog exempt. You can swap motors and tell the world and there's nothing DMV can do about it.

    Front brakes lock up in panic stop

    Front lockup is PREFERRED. Nothing is wrong with your truck. In a front skid scenario the truck skids straight. You can let off the brakes, reapply, and still be in control. If the rear locks up, the ass end of your truck will want to come around on you and the truck will rotate even with no...

    Heated & Cooled power leather seats

    My Suburban got a major center console upgrade today. My original center console was cracked and was overall very lacking. I scored a center seat from a 2010 F250 on eBay for under $200 shipped to my door. Similar to how I mounted the F150 seats, I cut the rear mounts off and built new...

    Heated & Cooled power leather seats

    No leg room issues. With the seat all the way down and the tilt column straight, there's a bit over 6"clearance. One notch up on the tilt column was 7" and all the way up was 9" Sent from my Pixel 4 using Tapatalk

    What material are 1987 v2500 hub caps made of?

    I did mine last month. Here's a before and after. I found the socket of the correct size that I could press onto the backside of the hub. Using the socket I was able to attach the hub to the end of my drill. Then I was able to spin the hub and use a Scotch-Brite pad to take off the clear coat...
