Better Traction, No Leaks, Big Block HEI Distributor And More With Mancini Racing

Mancini Racing has been serving the Mopar community since 1972. When it comes to Mopar aftermarket and what works, they know. Mancini Racing works hard to keep Mopar small block, big block and Hemi parts on the shelves and ready to ship.

They are always looking for parts to help fix common issues that can be found working on classic Mopars. One of those issues are leaky rear main seals in Mopar big blocks. Mancini Racing stocks their GraphTite rope kit part # MRE5297.

This kit is everything you need to alleviate your big block Mopar’s leaking rear main seal. Whether you have a stock crank or aftermarket, this GraphTite kit will work. No more oil stains on the driveway or at the next show.  

While you are fixing that rear main, you might look at upgrading your big block Mopar ignition to one of Mancini Racing’s big block HEI distributors. This one-piece, self-contained design requires just an easy 1-wire hookup to hit the ground running and produces a 50,000-volt spark through 7,000 RPM. These units contain the ignition module, premium cap, brass terminals, and high-power coil.

This HEI Distributor measures 14″ from the intake manifold flange to the top of the cap. To reduce interference, they have removed the vacuum advance and locked it out while tapering the shaft near the valve covers.

If you are looking at ways to make your Mopar faster, you might look into Mancini Racing’s Calvert’s Split Mono-Leaf rear leaf springs. These springs have helped many Mopars improve their 60-foot times while making your launch more consistent.

These units have aluminum bushings pressed into the front spring eyes and poly in the rear. They can handle up to 2,500 horsepower and are designed to work in conjunction with CalTracs.

They have also created a Plug-in Connector for Mopar electronic distributors to MSD boxes. This will save you the hassle of changing distributors if you are wanting to gain better spark control with a MSD 6-AL or similar box. The connector is 36” long so you will have plenty of length to mount your MSD box anywhere you would like. 

You might have noticed that Mancini Racing did not make it to this years Mopar Nationals but they do want to give a huge thank you to all the customers that came to Carlisle Chrysler Nationals. They said, “It was great being back at the best Mopar event of the season.” They plan to be back at next year July 14-16, 2023.
