Got a set that I pulled and put in TW6HG. Will sell them if you need them. They were too top loaded for the bagger owner.

       DM 598 is a good cam ..I would use the WT 46g here at the shop over the 598 as a 95 or 96 ci

My only concern about using the WT cams is how sensitive they seem to be to heads / exhaust requirements. Now maybe that's a wrong concept that I have gathered from feedback from users that have experience with WT cams, but none the less that's my current perception...  :idea:  :soda: :beer:

Running the DM.590 in my 113" bagger @10.3:1, really like the 42° intake close, and with the heads I have pulls very well in the mid and top also. At this cr won't make big peak hp #'s, but very well mannered and fun IMHO. + zero spark knock at any temperature & quiet.

You can make very good numbers with a Mackie 590 when everything is right. Great cam for a 95"

 the cams arn`t`t sensitive to anything .......cam timing is cam timing their a few cams out there with very close timing... infact were around way  before WT cams...the trick with any cam is the corrected compression ...cams closing say 48 to 62 require getting the corrected comp up to a desired need........sometime it isn`t easy depending on the size of the engine....it all can be accomplished.... that`s were a good engine builder comes in..........saaaaaaaaay me :wink:...the WT46 will be peppier than the DM598..............just watch your CR`s

are you saying that you port your heads exactly the same way for an S&S 585 with 245/260 int/exh duration .585 lift and a WT 26G with 248/242 duration and .575/.495 lift and all that matters is getting the cranking compression right?

what cams out there have similar timing to WT?

All very good questions.
My heads for WT cam use are not the same.

Agree. #'s may be more biased for hp than tq in the 95. I wanted mine the opposite and thats what I got.

The motor is my 103 bagger with 10.7ish CR, so I would still be TAD on the high end of 9.5ish corrected.

Thanks all for sharing  :teeth:

you got to be kidding.... I have 20 experience with every EVO HD head from 883, 1200... all the lightning series heads  to stock and SE 1340`s every  year TC 50 times over All the TCSE heads...Most years and size S&S heads infact i have a set of B2`s in next week....Zippers, STD R.I.P.  R&R to the latest Jim's 131 which got a wedge in the port so I could get more velocity and carry the flow to .750 lift....... not to mention 90% of those heads saw my flow bench.......with that said........I have used juuuuust about every cam in the old and present  book......definitely understand first hand  the characteristics  of those cams and their timing........how they will work on a 95 vs a 116 to 145 ci`s....I`ve been doing this for a while.

i did and i know of nothing similar.   you said there are cams out there with similar timing...which ones are they???

<<you got to be kidding.... >>

no i thought you were the one that was kidding with your statement about the WT cams -  "the cams arn`t`t sensitive to anything" - but who can argue with 20 years of experience.

I ran both the DME 598 and WT 46g cam in my old 95" HTTC setup... The DME 598 was 105hp and the WT cam was 85hp...  Same setup just a cam swap.. The TW46gh needs lota of compression.. 11+ or 12 to 1...

I have ran the DM 598 many times.. The woods W9F more......it  falls between both the WT46 and the DM598

  The WT46 couldn`t have been 20 hp off..........you messed up somewhere

I have to agree with Larry here. I had WT46G in a 95" w/HTCC CNC heads/pistons@10.5:1, squish a mile wide and still made 110hp/105tq. Aside from maybe noise issues, I think the majority of cams for TC's are very good, but if the tune is way off, or the build is overcammed, it's not the cams(brand) fault.

Any idea how the DM 598 compare to the Carl's speed shop cm600G?  Close to the same duration and lift.
