Lifter Clatter - New Engine

[Shaunp]

Thanks for that Shaunp. I'll pull one set and measure them when I get the car back. Could explain a few things..

These springs will put a huge load on the cam and lifters for no need. All solid roller cams a Billet steel not Sadi, I'd be concerned about premature failure of components. Its not uncommon to replace solid roller lifters yearly if the engine does a good few miles. For example the the Tran-am cars do maybe 6 meetings a year, typically they swap the lifters each season , along with chain rings and bearings, The needles break in them, some are solid bushed now.

Heads were ordered with hydraulic roller springs so all should be good.

Probably the 195 head springs they go to 7200 they are about 150 on the seat from memory. They are PAC springs.
