    Hi Guy's,
    Small block chevy, No waterpump or exhaust manifolds. Water pick up from rudder straight in/out, What is the best route to take??
    The block is a bowtie with two outlets in the centre either side of the block I only mention this because im not sure if thats what other blocks have?, Also whats a good hose size. Cheers

    Unless you never run slower than 20 mph you will need either cam driven or belt driven water pump.
    How about some pics.?

    Just food for thought. When the water of a stock SBC, or BBC enters the block, it does so at the very front of the block. There is no water ports in the block to allow water to enter the head until after its passed the first cylinder. The BBC has a port at the very back to allow water passed the back cylinder to get into the head. The SBC has some small ports that do the same thing.

    You notice that there is no such thing at the very front of the block.
    Now, ask you self, how does water introduced in the center of the block get to the very front of the block, if it has no where to go once its there. You can't blow air into a Coke bottle. If the water can't pass thru, it won't flow into that area.

    Consider allowing water to enter the head at some point foward of the front cylinder. There MAY be two small ports forward of the front cylinder as in the pic. Consider opening them up.
    Nothing wrong with a center entry. Smokey Yunick did it all the time. But you need to think about mods to correct for the change in water flow thru the block.

    Thanks, There looks to be two small ports At the back of the motor not the front, Can be accessed through Intake manifold base.
