A lot of our 3L guys have been asking for higher compression heads.
ATAT Performance Parts Australia can machine your existing heads to increase compression and re-machine the O-ring groove back into them.

To get this happening we need 5 more sets to commit before we start the run.
First in, first done. 🚤🔥

Calling all 3lt Merc guys and girls

The billet alternator bracket you’ve all been asking for is here.
Designed for high-performance race boat setups where strength and reliability matter.

To make this happen, the manufacturer requires a minimum run of 10 units, so we need at least 10 pre-sales before we can go ahead.

Pricing will be posted in the next few days. Keep watching this post.

We would like to start making 3lt engine parts,
In the comment section below please share with us what parts are needed to keep the dream alive for the 3lt motors
