Those don't look too very different from what you currently have, other than being on a 110 instead of a 112 LSA. No idea if there would be a noticeable difference in operation or not.

JM 20-22 specs:
Lift .496 / .520
Duration @ .050” lift 224 / 234
Advertised duration 300 / 310
LSA 112

Comp 42-423-11 specs:
Lift .505 / .505
Duration @ .050” lift 224 / 230
Advertised duration 276 / 282
LSA 110


Howard's 514825-10 specs:
Lift .560 / .555
Duration @ .050” lift 225 / 229
Advertised duration 278 / 282
LSA 110

 

I believe the first one is a flat tappet, the others are rollers. Worlds apart.
And looking at the @.050 numbers only tells part of the story. You need to look at the advertised duration, at what lift it was taken at, and the @.200 to get a better picture for comparison.

 

I totally missed that, so yeah not comparable at all.

 

I must have grabbed the wrong link, the 2 I was looking at are both flat tappets. Oh well...

 

Mark, forgive my ignorance but where do you find the @ .200?

 

Normally only in a Master Lobe file.
