    Not sure if this is the place to post, but I just bought an old Asplundh whisper chipper with a Ford straight 6cyl. motor in it. The exhaust manifold is cracked and I need to find a new one. Does anyone know what size motors they had in them(cubic inches)? And as a bonus, anyone know where I can get a manifold? Thanks for any info.

    Lots of them were straight sixes, 300 cu in straight out of pre-emissions ford p/u's. Look for 1977 or older- most likely direct match.

    Thanks Guys, I will go to the junkyards. They must have something. The fun part will be getting all of the old rusty bolts off of the old one. Lot's of Kroil and some heat I hope.

    Ford had two I-6 engines one was a 250-6 and the other 300-6. As for getting the exhaust manifold bolts out its going to be pure luck. If they snap off you hope they break off so you can slide the E/M off and then take a torch and heat up around the bolt and use visegrips to get the bolts out.

    The 4.9 I6 300 from Ford is a bulletproof motor. My F150 has 200K and gets 22MPG on the freeway. Strong motors that have a decent amount of power.

    There are several aftermarket manufacturers of the manifold.
    I would put a new manifold on it if you are going too keep it.


    They make them and there are plenty of dealers around.
    Actually not too expensive from Ford.

    If the bolts break just pull the head and get a reman for a couple hunderd bucks and get on with life.
    Or either have a machine shop drill them out and tap them.
    On a 300 they hold the intake and exhaust manifold on .

    Good engine for sure.
