I have looked in the searches and have not come up with anyone that has had this problem,so here it is:

I am VERY close to finishing this swap, but am having a hard time fitting the external water bypass from the water pump to the Edelbrock Performer Vortec intake.

Edelbrock states in there instuctions, that if you are using this intake on the late model vortec block, to connect the supplied hose from the intake to the water pump.

Problem is, they do not say if that the original vortec water pump was to be used or not.

The LG-4 water pump top fitting does not line up with the fitting to the intake, has anyone seen this before and found what works?
Is it just a matter of finding the right hose fittings? Please help!!!

I have looked and saw that there is no hole in the block for the bypass, and I'm not taking the chance at ruining the block trying to drill holes in it.

I also want to keep the older style water pump so I can keep all my original brackets and accessories and direct drive fan

Thanks,Third Gen, and sorry if this was too long!!!

 

HEY.. the best advice that I can give you is to take a look at a VORTEC truck... 96-2003... chevy trucks ALL have VORTEC.. If you don't have one or know someone who has one... "shop for cars" act like you wanna buy a truck from a used lot.. say you wanna look at the motor.. and then change your mind.. There SHOULD be a bolt block (or hose fitting hole... on the top of YOUR water pump) look at that part on the VORTEC truck and follow the HOSES.. to the manifold.. Sorry if that wasn't much help .. BUT.. that's all I can think of. YOU SHOULD BE LOOKING AT THE INTAKE not the block... ok
GOOD LUCK

 

Thanks for the reply, and yes I am looking at the intake for the EXTERNAL bypass, as stated earlier, my reference to the block was that is where the older SBC uses an INTERNAL bypass.

I was just thinking of taking a look at a Vortec truck to see how the factory handled this, so thanks again.

My concern is that they are using a water pump of a different design than mine, that would have the correct mounting location, as to where I'm trying to use an older style water pump, that doesn't

All good advice, but I have recently read that if the internal bypass was blocked-off, or otherwise not used, that by drilling (4) 1/8in. holes in my thermostat would achieve, the same,if not better results, and I can plumb my heater hoses as before, and not even worry about an external bypass at all
