    Chevy E-Rod LS3 Engine Swap

    Has anyone swapped a LS engine into a mid 70's 4X4 truck? If yes, how did it work out and how do you like it?

    Does installing a LS1 into a S2000 count?

    Sure! Sounds like a tight fit. How is performance?

    To see what I am working on, google "Import Muscle". I am going down a well beaten path here....I am about 90% complete with primarily the wiring harness as my last major hurdle. I also have to figure out the intake plumbing and complete various details including heat shielding parts of the exhaust, battery placement, and radiator hoses.... I only work on this project when I feel like it and it has been on the back burner for awhile now.

    As far the LS engines for swaps....they are awesome compact and powerful. I am a big fan of these engines.

    I am big into Subaru engine swaps and conversion and building standalone harness's and merger harness's etc.

    That said I did get a LQ4 6.0L iron block truck engine last summer on trade it was 100% complete with the drive by wire pedal assembly and all the harness, sensors, accessories and wiring.

    I built a standalone harness/fuse block using the factory ecu, had the ecu cracked in HPtuners by a friend ... and had it running perfectly on a engine stand in my garage. I have a old first gen S10 squrebody that I plan on LS swapping & boosting in the future.

    I ended up selling the swap to another friend and he installed it into a two door Nissan G35 backed by a 4L80E.

    Any questions on that part just fire away.

    What are you planning to run for a trans? What about the engine management side?

    I am contemplating putting an LS engine in a '77 Chevy K10. It has a 4 speed w/granny first, 3.73 gears, 33" tires, and plans for a Gear Vendor overdrive. I live in Calif. and have to be careful what I do as I could end up with something the smog people won't accept.

    The other option is re-ringing the 350 engine in it now, or a crate replacement.

    The E-ROD swap is Calif. compliant though a little on the pricey side.

    The harness is the part I have little confidence or experience with...It will use the Honda ECM to control the digital dash and the electric power steering with input from the LS1 harness....I need to get the LS ECM reflashed to eliminate the VATS (anti theft) and turn off the second set of oxygen sensors. I also need to either send the harness out to be stripped/stand alone or attempt it myself. Never done one before, a little nervous here and some avoidance going on here!

    I am using the T56 six speed along with a custom drive shaft, custom half shafts and hubs, and a 2010 Camaro SS differential.

    I appreciate your offer to help! I may/will have a few questions for sure as I learn more and get up to speed!

    That things going to be a animal.

    Is the S2000 can-bus ... what year is the car?

    What intake manifold are you running?

    Cable or drive by wire throttle body?

    What's your ecu and harness out of?
