Here are pictures of the GT3 pump. Note extra scavenge pick up.

Rob,

Is this pump going in the cup car ... or a different engine?

It is being considered for a different engine with a 2 liter crankcase, but seems would be a nice direct replacement for the one in a 3.6 liter as well.

If I needed a new pump in my Cup the GT3 version would be the one I would chose.

Steve,

"No problems.

As you know, the case must be clearanced and the bypass modification performed, but thats it.

Just make sure that the scavenge plumbing on the car is big enough; -16 is minimum.

** What is the bypass modification to which you are referring ? What exactly needs to be done.

Also upgrade to Turbo squirters while You are there. On my 2.2 I used the non CW crank, had it knifed and balanced, turbo squirtes, JE pistons(much lighter), stock rods and rod bolts(no ARP option when I built it 7 yrs ago.) Ran it for 4 seasons and sold the car. Was a wonderful motor, used a WebCam S+1 grind , shortshifted often but did run it up when needed. Obviously much of that advice goes counter to what You hear and we did have to adjust the valves 2 times....lol

Here is the bypass mod, crankcases built after 1976 have it already.

The squirters were installed in 1970.
