    Will be swapping in a built 99 Cobra engine.

    So, itís getting close to time to start swapping out my stock 67k mile engine to a built cobra engine. Said engine has a Steele crank, h beam rods, and dss pistons. Block is suppose to be a teskid block as well. Exhaust ports have been ported on the heads and thatís about it.

    For those that donít know, I broke a ring land in cylinder 3 last year and itís been sitting every since.

    I guess I said all that to say, point me in the right direction for the best instructions and/or details on what needs to be done for this to work in the Marauder. Thanks in advance. A few pics I took tonight.

    While doing some research it appears I may have to use the oil pan from the Marauder and possibly the timing cover. I am doing some research myself, but Iím mainly seeing 03 Cobra swap write ups.









    The intake from the engine

    Thanks guys. I think I also saw something about a flex plate possibly being needed. Can anyone shed light on that?

    Looks like a TEKSID block....3 pronounced braces cast on each side of the valley and square shaped cross hatching pattern in the middle.

    (WAP blocks have diamond shaped cross hatching.)

    Forged cranks use an 8 bolt flexplate vs. 6 bolt for OEM cast cranks.
    I have a non SFI rated 8 bolt flexplate...never installed.

    I believe you are thinking of an IRON block.

    Sorry no Jordan. But anyone with a stock flexplate can confirm as itís the same as stock. I think I thru out my original.

    I believe the differences are mostly in bolt pattern to the converter and possibly the offset. I gambled on EBay for like $38 shipped and scored a used one that I never even used LOL. I gave it to LowbuckMM and it bolted up just fine on his. I think it was an Ď05 E150 or 250. Try to confirm first.

    I did. Looked it up in advance auto website. Thatís what it gave me. I was just trying to confirm the O.D was correct.

    Also, is there something that has to be done to the oil filter location?

    thats the wrong flex afaik they use the larger converter, been there done that

    prw makes an 8 bolt small converter pattern flex plate for the 10.5" gm torque converter pattern. Simply wallow it out slightly with a drill and its perfect everytime. Ive done it numerous times.

    This is what I used on my build too. I've read where some re drilled and some had to open holes. Mine fit the PI convertor no problem.
