water pump/MSD intake problem
Is anyone using a Vintage Air Front Runner system with an MSD intake? The water pump interferes with the MSD right below the throttle body flange. I looks too severe to try and clearance the two parts. Probably would need a good 1/4" - what a pita...
thanks.
thanks.

On the LS7 C6 Corvettes there is a little issue like you have but the water pump I have looks different. What water pump is that from? I had to file some off but not as much as what you have there. Are you sing a 90 or 102 TB. BTW if you can use a C6 water pump get the 2010 and later pump the hose that you have taped up in photo was moved over to the drivers side for more clearance with issues like you are experiencing.

Thanks for responding. This is a system that Vintage Air designed. They use their own water pump design based off the LS1. I called them and was told their system is designed around the GM intake. I am using a 102 TB.
The problem is, I have to use their pump if I want to use their 'system' because of the spacing and alignment issues. I already have big $ invested in this approach. I need to try and find a solution using these parts first...

Options are to cut the ear off which is the rout I went or to switch to a Ls2 water pump but it has to be for a corvette. They do not have the top bolt ear.

That's the way I'm leaning at the moment. But I was also thinking about tapping a 4-40 screw on either side of the bolt to help maintain the seal.
You didn't do anything special to help seal?

If you are running a 102 throttle body and need to use that water pump, that ear needs to go.

Well, I lopped it off - not enough. I still need 1/4" in the vertical direction and 5/16" horizontally (towards the engine). Not much room to clearance the intake/TB and taking that much from the pump will surely hit water. This is not fun.
I'm thinking about buying an LS1 pump (which they used as their model) and seeing what changes they made and whether or not I can make it work.
Any particular year/model pump I should look for?
Thanks.

That's funny. I was looking through Summit last night and saw those - came to the same conclusion. I need to measure the hub height on the Vintage Air pump and see how the two compare. It looks like I may even be able to use the same pulley...
Mucho Gracias!

I did the same but went with the GTO/Fbody pump with the bell pully - I thought researching showed the Vette LS2 pump didn't have the right alignment to work with the Fbody accessory drive? I haven't installed mine yet, still collecting parts.

I'm pretty sure you would need a spacer for the Ls2 corvette water pump but it does not have that top bolt ear that needs cut/ shaved

So, I ordered an Edelbrock pump. It looks like it will clear and the block to hub height is only 1/4" shorter than the Vintage pump. I should be able to just shim it and may be able to even use the same pulley...
I will let ya'll know if it works. Some one down the road is sure to run into this same problem.

Thanks. I wasn't intending to shim the 'pump' itself. I was going to try and make an adapter that pushed the pulley out 1/4". Seems a lot cleaner and less chance for leaks.
