We'll post up with pics as soon as they're ready!
The new scraper will be designed for:
- 4.000" stroke with aftermarket rods
- ARP main studs
- ARP rod bolts
We will continue to make a scraper for the 3.622" stroke factory bottom end. Does anyone see a need for a scraper for the factory 3.622" stroke with ARP studs and rod bolts?

0.040" +/- 0.020" is what we shoot for. You can use feeler gauges to check the clearances.

Not yet, we are still waiting on a few parts for test fitment. We will get it out as soon as we can.

ARP main studs also require a completely different scraper because the studs are bigger than factory, so all of the holes have to be larger. They are also slightly taller, which will affect the geometry of the scraper a little if we want to maintain the same clearances for maximum performance.

Awesome, thanks for posting the pics! We got a set of ARP rod bolts and we will be updating our scraper to add that little bit of extra clearance. That amount shouldn't hinder performance significantly if using factory bolts, either.

To clarify, are you using the factory crankshaft or aftermarket? Even if it's the same stroke, a forged crank will require a different scraper than the factory crank.
