LS3 Conversion - 67 C10
Alright gentlemen and all others. I was saving to do this project by 2013 mid-spring but seemingly lost compression in the #3 & 6 cylinder on my SB400 on my way to work last month. Block crack
My granddad and I had done that engine back in 1997, it had served me faithfully, but was due to die soon; it was my highschool engine and served me well even under the brut force of a 16 year old foot. ![]() Alright, purchased an LS376/480hp connect & cruise engine from PacePerformance with a few accessories. Looking at two issues thus far... my fuel (tank) and my gauge set up. Any recommendations? Right now running with a rear fill, rear-mounted tank I bought from LMC truck (21 gal) about 7 yrs old. Would like to continue to use it but don't know if there is a kit out there to convert to an internal pump or external pump that wont quit on me every 15-20k miles and wont cost what a new fuel cell will cost And the gauges... thinking about www.dakotadigital.com or a www. http://boeseengineering.com setup, see website (67-72) dash clusters. HELP ME OUT!

Welcome fellow aviator and helo bubba! Good looking truck, you'll like the swap. You'll have to make the trip to Pensacola when you get it completed.

Re: LS3 Conversion - 67 C10
Sweet truck! I used a Boyd Welding tank with an external pump, but you can get it with a Aeromotive Stealth in-tank pump for $648. http://www.boydwelding.com/ Keep us informed on your progress!

Re: LS3 Conversion - 67 C10
Any LS3 convertors out there with fuel system ideas? External Pump
I want to go with an Aeromotive A1000 external fuel pump with A1000/6 regulator; has anyone had any problems going with an external pump? Did you have any problems with the install? TIPs?

Re: LS3 Conversion - 67 C10
Mount them as close to the fuel tank as possible. These style pumps are better at pushing than pulling. I have also heard that it will increase the life of the pump.

Re: LS3 Conversion - 67 C10
Installed engine this morning along with Flywheel in preparation for the transmission (Following 2pm beer call). The BRP motor mounts were perfect, no issues, installing transmission and starting ECU hooks this afternoon.
Anyone know what the dimensions are for the driveshaft changes...(o/a figures) will be measuring but would like to have a good idea before doing mine First picture is rear of LS second pic is the Old SB400

Re: LS3 Conversion - 67 C10
Beautiful truck and very nice engine choice. We need more pics of your truck. I'm subscribed for this one, an ls engine will definitely be my next motor once I'm tired of my BBC.

Re: LS3 Conversion - 67 C10
Engine & Transmission are in and we've started hooking up the ECU. 1) Noticed the oil pressure sensor (not sender) has no adapter; most other sensors had an adapter.... will have to track that down.
Transmission has no Fill Tube/Dipstick - ordered a LOKAR firewall mounted tube from summit. As far as cooling lines, I ordered some for a 73-82 pre-bent 700R4. I haven't attached them yet but I can't imagine too much more bending for fitment. Will probably mount the fuse box to the passenger side fender and ECU to the firewall. Power steering. The LS3 has a GEN II type system with external reservoir the steering box on my truck is of course different. Without going to the local tractor place to custom make hydraulic hoses I ordered a kit from summit as well; billet specialties #77900 kit. Summit makes a Kit I'd prefer to have ordered #SUM-G3160 but are out of stock. Going to install a bypass for the heater until I recoup the money spent from the install and invest in a GEN IV vintage air system
