I had a power steering pump in my gen 3 funco spring a leak over the weekend. I have it out and a newish one installed but for what ever reasons when putting it all back together the toe in ended up being very extreme. how much is any toe in if any should i be aiming for?
currently i have it down to approx 3/8in per tire when measured front of tire to the back of the tire.

The longer rack is going to mess with Ackerman as well. May or may not make a noticeable difference in cornering.
 
The key is making tie rods equal to control arm length. (so get a rack that can accommodate this) Or as close as you can to reduce change as suspension cycles. I also ran between a 1/4 and 5/16 toe in on mine.
 
1/8" toe in at ride height is standard for most race cars. Have you determined how much bump steer your Funco has? I would set it so you are in the middle of it at ride height.
 
ok thanks guys i think i have an idea where to go from here.

rack & pinion is like for like ( same part number for the 93 Mustang it came out of ) . i forgot to take the toe measurement when i took the old one out but i feel that the rod ends on the replacement are slightly shorter than the one im replacing.
 
I have always run 1/8 to 1/4 toe in. At ride height. As others have said, check it a full droop and full bump too. It sucks if it goes toe out as it gets closer to bump. This means if you hit a bump on one side, the car will steer into it. I had this issue at one time, car sucked to drive......

Did you take rod ends apart when you removed the rack?
 
Toe in will make for less tramlining on ruts.

Toe out makes for quicker turn in.

There’s also bumpsteer to consider, as noted above.

I may be using the incorrect terminology. the length of the rod sticking out of the R&P i think is slightly shorter.

If you didn't do anything to the length of the tie-rods and you now have considerably more toe in than before, end to end the rack has to be longer (I'm assuming the Funco is rear steer). Just something to check.

As long as you can make the toe you want it will be fine. If you end up too short you can get joints with longer threaded area on them to correct the short stub out the rack.
