    The 86022 is the BBC 2WD version.
    The 86089 is the BBC 4WD version.
    The 86089 versions specify they do NOT work with a manual transmissions...

    yet the 86022 says it won't work with the 4WD truck...

    Anyone know which version I should get?

    Yes - I have a BBC manual transmission 4WD Blazer.

    Thanks.

    Hookers are over $120 more than the Dynomaxes. /forums/images/graemlins/frown.gif

    Unfortunately you get what you pay for in this case. I have hookers, and they do fit better than the Dynomax. But they are tight. The key is LOTS of patience.

    Don't you have Hydro cluch?
    If you do then the only reason they would say it don't work with a manual is due to the Z-bar being in the way??
    I am totaly guessing....
    PS have you looked into the Hedmen Elite brand? This is waht I will be running on my BBC454 Hydro BadASS First Gen K5 /forums/images/graemlins/thumb.gifheheheee /forums/images/graemlins/thumb.gif

    I am pretty sure that is the reason. The Z-bar is the "in the way thing", but without ever seeing a hydro setup, i couldnt tell you for sure.

    Yep, Hydro. I thought it was a bell housing issue.

    I forgot about the Z bar... /forums/images/graemlins/crazy.gif

    I had to sawzall a piece of my hydro bell on the passenger side because of the headers on my small block.

    There's a guy who is selling the BBC headers from Dynomax already ceramic coated. But they are for the two wheel drive model(s).

    According to Dynomax the primary tube lengths are different between the 4WD and 2WD models.

    I have looked at the other brands, but they are all MUCH more expensive.

    Dynomax coated headers are the same price as almost all other brands UNCOATED! /forums/images/graemlins/eek.gif

    To keep the low-end torque and street driveability only 1-3/4" primaries (on the BBC) are more than adequate. We tend to lose power and performance with anything bigger. You might gain another 5hp with larger primaries at 5K +. But IMHO it's not worth the added expen$e.
