    I?m making a set of headers for my 1938 Oldsmobile business coupe .I have a question?

    Hello I have a 06 lq4 out of a 3500 express van.
    I?m making a set of headers for it now I?m second guessing my o2 sensor bung location.

    Thank you kelly

    I see why they charge 2000 and up for a set of custom headers I have 20 hours in the drivers side and passenger side is harder I loose 2 inches clearance from frame from the starter bump .

    I would move it back 5-6 inches.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    No.

    You could have it another 12-15 inches back and it would still be okay but another half foot back would be better than where it is now.

    thank you.
    I’m glad I posted a pic and had second thoughts of placement.
