426 HEMI AUTO LOCKING DIPSTICK

Did they quit making them ? . Can't find one. Also which is best with 2 1/4 tti headers

I bought the one for my 440 from Mancini Racing.

Nobody makes a good one for the Hemi with headers. I tried and tried to make a stock one work, but ended up having to modify one that was supposed to work with headers from Maninci.

440 will not work

By the title of the post You're looking for a locking trans fill dipstick, correct?

Cope Racing Transmissions sells them.

All their locking fill tubes.

My car is a 572 Hemi with TTI headers.
The only problem I've had with it is that I had to make my trans funnel do a 45 degree angle at the tip to put fluid in it.
If you have a flexible funnel it shouldn't be an issue.

I use the Lokar flexible braided dipstick that mounts to the firewall.

That is the way to go and what I will use on the Ramcharger.

Thank You very much !
