Power Gain With Solid Lifters

[wsa111]

Mike, i hope you read this.

I would like to see whats available in solid lifter camshaft designs.

Many inport manufacturers still use adjustable valve trains.

I feel there is power to be gained by going to solid lifters on a high performance engine.

Yes hydraulic lifters are easy maintenance.

If you look at solid lifter specs add about 6 degrees to the advertised duration specs compared to a hydraulic lifter camshaft.

A 284 degree solid lifter cam would be very close to a 280 degree camshaft duration of a hydraulic design, but the lift @ .050 would be very much higher because of the solid lifter design.

The use of a solid lifter camshaft would prevent lifter pumpup in the higher rpm range, over 5500 rpms & give you a faster rate of lift + another .030" of total lift.

The use of solids are only as good as the correct valve lash maintained by the owner.

Lets see what the camshaft grinders offer, i feel there is power to be gained if you take the time to properly adjust the valves.

Lets see whats available???? Bill

No problem, Clay Smith will grind up any profile I want. I'm going to call them on Monday, and see what they recommend. Then I'll probably stock two or three profiles.

We've been using soild cams on all the turbo motors we've been building. I've been trying to get Will and Kelly to switch over, as it would definitely help their ETs.

Just out of curiosity,how would a roller cam work in our 6`s?Or,would it be a waste of time,money and effort?
Thanks.

Leo, the TC racers in Argentena are using Roller cams the main issue is setting up the dog bone.Jessel has a sleeve with a groove that can be installed in the lifter bore but they are not cheap at about $60 ea.WE are working on it though I think thats one of the next things on Mikes' list.Wonder what a 250 sounds like at 9k rpm?

Uhhhhhhhhhhhhhhh,at $60.00 each,are they made of Platinum, or UNOBTANIUM?hehehehe.Thanks.Will be looking forward to any articles or info on the developing situation.

I would be interested in a solid cam also mike, I didnt think we could get solid camshafts for our 200/250 engines.....keep us informed
