Tool steel lifters
Had problems with shubeck lifters (Lifter puck desintregated on dyno 2 times). Customers wants to run tool steel lifters in a 64 MaxWedge426. How much spring pressure should I run with them? Thank's!

Re: Tool steel lifters
Don't know about how much spring pressure you can have on tool steel,But how much spring pressure did you have on the Smith lifter when it shattered and how much rpm.Just curious .

Re: Tool steel lifters
With the correct tool steel lifter, and camshaft, with the correct surface treatment, you can run as much as 550 open pressure.
Do not, under any circumstances, run a DLC coated tool steel lifter on a cast iron core camshaft.
