    Vibes after motor and trans swap.

    Hello guys/gals, Ever since I did my LS swap on my 87' C10, I've had some rough vibe issues from idle up to about 3000 rpms (This is approximate as it's been awhile now). These vibes persist whether I'm in Park or driving under load. The reason I'm posting here is to get more exposure and the...

    First start complete, now what? Lol

    Hi guys first start on Old Brown finally. Hard to hear much of anything but there is a funny racket there. Almost sounds like a power steering pump at first but you'll notice the sound drags on shut down. Any ideas on what this sound may be? I'll be putting some temporary mufflers on her...

    2010 Camaro SS starter wiring

    This is the starter for my LS3 off of a 2010 Camaro SS. There's 2 ring terminals and one connector. Anyone know if I'll need to hook up the connector or do I just use the two ring terminals for my battery and signal wire? Thanks!

    6/8" lowered and driveshaft length

    Hey guys, Will I have to worry about my 2 piece driveshaft length with my dropped 87' long box? Will the rear shaft need to be shortened? Thanks!

    LS3 stock tune but running headers safe?

    Hey guys, My LS3 computer has a stock tune for now. But my motor has a CAI and headers on it. I'll hopefully be firing this thing up on Friday. Am I safe to be cruising with a stock tune on a CAI and headers or will she run too lean? Thanks!

    Vacuum bowl required?

    Is this vacuum bowl required any longer on my truck now that I'm running an LS3/4L80E? I've read that there's a vacuum line that supplies the HVAC unit in the cab but I can't see any vacuum lines going through the firewall. Was this only for trucks with AC? Mine doesn't have AC. Thanks!

    Alternator wiring

    I know I'm flooding this forum but all this little stuff has creeped up fast! My PSI harness is wired to the LS3 alternator with an OEM connector. But my factory truck harness has an alternator wire as well that used to bolt to the back of the alternator. It's also wired to an OEM...

    Where to find "cranking" power wire?

    It's me again, I'm getting so close to being able to fire this truck up. Anyone know where I could find a key on, cranking power wire on my 87'? ( I need a cranking power, not just switched power) I'm guessing it would be around the ignition area? Thanks again guys, you're a wealth of knowledge!

    What else do I need to wire up?

    Haha sorry for all the posts. I've got my engine and trans all wired up with PSI harness. Can anyone let me know what else I may need to wire with the factory truck harness? I have the wires for the coolant temp and oil pressure wired but that's it. There's still a lot of wires to sort...

    Anyone know what this is?

    I've got my motor all wired up now with a PSI harness. Now I'm sorting out the factory truck wiring. Does anyone know what this electric connection is that is mounted to the firewall that is above and to the right of the heater core hoses? Is it a relay for something?

    Hey guys! Well been busy with a bunch of other things but finally have some more time to put into the truck. Can someone steer me in the right direction on my coolant line routing? I've included two pics. I believe in the first pic, the coolant runs from the water pump to the lower rad...

    To clean or not to clean injectors?

    Well...I'm getting really close to firing up this LS3! :893karatesmiley-thu I've read in more than one place to have the injectors cleaned out before even attempting to start your motor if it's been sitting for any length of time. Mine hasn't run for at least a year that I know of. What do...

    1 piece or 2 piece driveshaft?

    Hey guys, I thought this would be the best place to post this question. I've done an LS/4L80E swap in my 87' 2wd long box. I still need to get a driveshaft modified for it. The original driveshaft is a 2 piece. But I also have a 2 piece driveshaft from an 04' 6.0/4L80E. My question is...

    What sensors are these?

    Hey guys, When I removed my old 350 TBI from my 87' 1/2 ton, there was only one wire I had to cut. And I'm not even sure what it was for. But...does anyone know what sensor it is to the left of the flex plate in this pic? Looks like it had a heat guard or something of the sort around it. I...

    LS3 swap thread

    Well I've posted on and off in the forum doing research for my LS3 swap in to my 1987 2wd long box. I figured I'd try and maintain a swap thread of sorts. I'm mechanically inclined but my experience is only limited to one Fox body engine swap, oil changes, minor repairs, and bolt ons...

    Aftermarket in tank fuel pump

    Hey guys, I purchased an in tank fuel pump kit from PSI Conversions for my LS swap. I'm installing their pump in a 25 gallon Jimmy/Blazer tank in my 87' R10. I know I'll have to cut out the hole in the middle of the tank to fit the new fuel pump, but where am I going to fit my fuel sending...

    4L80E long shift shaft question

    Hey guys, I'm throwing a 4L80E with the neutral safety switch and long shifter shaft into my truck. I also picked up a Lokar cable shift linkage but it says it will only work with the short shaft on the 4L80E. Does anyone know the part number for the short shift shaft? Is it the same...

    25 or 31 gallon fuel tank relocate?

    Hi guys, I know I've run across this info somewhere in a thread in the past but of course I can't find the info when I need it. I'm ditching my saddle tanks and I'm ordering a Blazer/Burban tank for my 87' C10. It's currently a long box but it will be a short box next winter. Can...

    Which wire harness company?

    Hey guys, I'm slowly moving along with my LS3 swapped 87'. I was going to tackle the wiring myself but I don't feel 100% confident in my abilities and I'd rather just have it done right and plug and play. With so many companies out there building harnesses, can someone recommend a...

    Adaptor for LQ4 water pump outlet?

    Hey boys, Has anyone come up with an adaptor to change the outlet on the LQ4 water pump so it discharges in a forward style similar to the LS3/L99 water pump? I wanted to do the 2010 Camaro water pump mod but by the time you purchase the pump/tensioner/adaptor/pulley etc, it's a damn...
