    67 Firebird-Part 2

    After finishing and driving my Firebird for more than a year with the old school Pontiac drivetrain, I kind of grow tired of coming home smelling like raw gas due to an exhaust leak (I think). So I decided to do an LS swap on the car, and put the entire drivetrain for sale to fund my swap. The Mustang I was working on will have to take a back seat.

    Shortly after the drivetrain was sold to a local Firebird enthusiast, I picked up a complete 5.3L/4l60e combo supposedly with 81,000 miles. I did a leak down test and the percentage loss was around 14% for all the cylinders (cold engine) so I think I'm good. Going to use the motor as is (maybe change out the timing chain/oil pump).



    The old Pontiac motor ready to come out.







    LS mounts from DSE.



    Ordered the Mast oil pan, since DSE said the truck oil pan hangs too low and interfere with the frame. Funny the new oil pan costs as much as the entire engine.

    DSE mounts installed







    Just as I suspected, the truck oil pan hangs too low, and contacted the cross member before the mounting holes on the pass side got lined up.



    I guess I have to pull the motor back out, and install the Mast pan, which came today.

    Quick update.

    Mocked up the Mast pan, which cleared everything







    Quick shot of the engine/tranny in car



    Initially I was going to mod the T400 crossmember for the 4l60e, but turned out I had to cut it up too much, and it was additional work that I did not want to do. So ordered new BMR crossmember from Summit, along with Dynatech headers. Also I ordered a new fuel injected tank set up from Tanks Inc.

    Worked on the fuel tank over the weekend. Got the pump and sender mounted in the tank.





    I decided to make an access hole in the trunk in case I need to remove/replace the fuel pump/sender.

    The sheet metal around the access hole kind of flexes a bit, so I made a trim ring using my new bead roller to help stiffen it up a bit. Not the prettiest, but it works.

    Welded in place.


    Then I made an access cover panel.



    Ordered fuel lines and an fittings. Hoping to wrap up the fuel system in a week or so.

    Mounted the BMR x-member. Overall the parts fit great, but probably will install much easier if the subframe is out of the car.



    Also started running lines for the fuel system. Got Corvette fuel filter/regulator, Swagelok compression fittings







    About $200 worth of braided line/AN fittings.

    Mounted Brian Finch's dual vent, and relocated the battery back to the trunk.



    Lines ran for fuel tank. Just have to figure out whether I want to keep the fuel rail inlet on the driver side (stock), or flip it 180*.

    I decided to mock up the truck accessories, and to my surprise, it's too tall. It's probably due to the DSE mounts, since I've reads over LS1tech that some used truck accessories on 1st gen F-body and it clears.



    Time for new LS accessory drives. I really want VA front runner set up, but the price is way out of my league at this point. I may have to get the Holley set up.

    Thanks for posting all of this!! I'm hoping to do this conversion at some point. I can't believe that that oil pan is $500!!

    I haven't seen anybody run truck accessories in a first gen. The Camaro/GTO setup is pretty compact. I think the C5 Corvette is the most compact. Not sure about the C6 vette stuff.

    Rod Prouty's build thread of his 68 has a picture of the truck accessories mocked up. Looks like it cleared the hood. I'm pretty sure that the DSE mounts I'm using raised everything up. On the plus side, nothing from the motor/tranny hangs below the crossmember.
