I am not going to say no maintenance but way less than you would think.

Has Jesel keyway lifters and small light springs light titanium valves.

The upfront price for this type parts is high but return on investment much better.


I can do 950-1000 HP W8 deal that will go 100s of passes with next to 0 maintenance.


My 880HP 411 w8 engine built for engine masters in 2011 has 150+ dyno pulls 100s of passes in my car 8.80s at 150mph

Then it went in Brad Bowers dart for drag week NA small block (we won😉)

She is still together 10 years same rings and bearings.

I did change springs for drag week. 🤪
