    Alright guys, in the planning phase of this swap, i'm gonna lay out my plan and how much i think it's going to cost, you guys tell me how far off/unreasonable i am.

    Timeline: 1-2 months.

    Right now-planning

    Next week-Try to buy the motor and transmission, as well as swap mounts.

    Next month- buying smaller pieces (fuel pump assembly, gauges, etc)

    End of next month- Start installation, gonna try to knock it out in one weekend, start friday morning, end sunday night, sleep optional.

    Costs-
    Drivetrain-2800 (engine, transmission, full dress.)
    fuel- 500 (tanks inc kit- 240, vette regulator and misc AN fittings-260)
    Driveshaft shortened- 100
    Swap mounts-500 (BRP kit)
    Accessory Brackets (dirty dingo)-240
    Cooling-(radiator hoses)-50
    Misc. costs- 400

    As far as the PCM and tuning goes, it will be already done when i receive the motor.

    So far this puts me at 4540. This is worst case scenario, buying name brand parts. I know i'm missing something though, my original calculations i did yesterday put me in the neighborhood of 5700. Thoughts?

    1. Thats a good deal/estimate on the engine.
    2. Tank mods might probably going to take you a day
    3. BRP is expensive. Look into Ebay adapters for $30-$50
    4. Are you going to use Truck intake?
    5. Harness mods?
    6. Radiator fans?


    I think you have a good estimate. Good on the Misc cost, because you never know lol...

    No to the truck intake, im just gonna buy an ls1 outright. Yeah i could buy a truck setup for 1-1.5k less, but by the time you factor in sourcing all the little parts and the time, to me its worth the extra money to buy the complete motor. If i dont use brp i want a kit that includes the engine and transmission mounts, ive read horror stories about how people buy two different kinds of mounts and their pinion angle is off, heads hit the fire wall, etc etc.... ive already got an electric fan in my car, and im not sure what im going to do about the harness just yet.

    What are you planning on doing for exhaust? Also doesn't the BRP mount kit work with the factory f-body accessories? That would save you from needing the dirty dingo kit.

    And the harness, i would do it yourself. Its easy to do

    The brp kit is just the mounts for the engine and transmission, not the accessories! and i have not a clue in the exhaust department, probably just run what i have now! Dunno if the manifolds will fit though.

    From my understanding, that kit is designed specifically for the f-body ls1 so the factory accessories and oil pan will all clear.

    For tge exhaust i would highly recommend the dynatech swap headers

    For the ECM tuning, make sure the VATS is disabled. Also, the ECM can be tuned for your gear ratio and tire size so that the VATS can send an accurate signal for speed.

    As for the headers, I also would endorse the Dyantech swap headers. They fit well. only downside on my install was the header bolts they provided in their kit were the wrong thread size and pitch. Had to re-use the stock manifold bolts for now.

    As for the timeline, a weekend is pretty aggressive. You might be able to knock it out in 2 weekends, unless you have help from a couple friends.

    One weekend? Having done this by myself, I can't see that being possible but more power to ya, hope you can do it. The details are the killers. Just the fuel system front to back (fluid and electrical) could take a full day.

    Setup a time lapse camera and go for it.
