918s if installed at a 1.77" spring height will yield 135 LB seat pressure. Do we really need any more than that with these cams?

If I remember correctly, the stock LS1 springs get you only about 70 LB seat press.

Ron,

 

Anyone see the article on conical springs in Hot Rod?

...very interesting ...it said the concial spring is desiged to provide a minimal amount of stress on the train...also said the tapper at the tops allows the use of a small diameter spring retainer which decreases sprung wieght...

...I considered purchasing the 918 conical spings for my H/C job but opted for the Lunati REV doubles instead ...these are not conicals and put a bunch more pressure on the train...


...they have Ti retainers but are not significantly lighter than stock Z06 spring retainers...

...I did not buy the 918s since I heard they broke often....

Did I make a bad decision?

 

...the article was in High Performance Chevy not Hot Rod ....it is the rag where 99% of the build-ups are running those anceint carberator things...
obviously, they are living in the stone ages...

 

Are conical springs called beehive springs?

...just heard that and wondered....
