The 37 was a big time popular cam a few (3 or 4) years ago.

Seems like there is a new "cam of the month" every year. Sounds weird said like that, but it is what it is. Great cam for the 88, 95, 98 builds.

Seems like the 555's are the cam of the month this year. (96, 103 builds). I'm still not sure they are any better than the 54's from last year. I think I'd lose power trading my 54's for them right now.

 

The 54 looks to be a good performer and have considered it along with the 37 in my 97" build

 

For your information and interest, I've posted some of my data on the thread linked below ... check it out .... (well, general interest and information of pretty much anyone, I suppose ....)

A lot of work and good data. The data confirms that most owners tend to over cam whan planning performance upgrades. I am sure that most owners that are disappointed with ugrade results selected a cam that was too "big" for the build. I was talking to one of the Andrews guys about cam selection several years ago and his advice was to do the homework, pick a cam and then go down a tier.

However, if the OP is talking to Don (Deweys Heads) Dorfman and Dorfman likes the 37 for the build, I would take is advice if he ported the heads.

 

Agree on the caution not to 'over cam' ... one of the reasons I started that thread and posted the data ... hopefully as a service to those who were 'doing their homework' ....

I was planning on going with Andrews 54, originally ... then, was thinking I might be overdoing it and 'moderated' to a 37 grind ... I think I did the right thing ....

Kinda lookin at the wood tw7h6r to go with the cam chain upgrade the Bob has,Don is lookin at the specks as he is not familiar with this new cam.

 

Speaking of not over-camming, we built a 117" with a Wood 6/1.725 rockers, set at 10.3 cr, for a client in San Jose last winter, that was tuned by Bruce at Horsepower Express, in the San Fran Bay area.
Our Stage IV, 2" valve head, 55 HPI, S/E slip-on mufflers.
Final SAE, was 118.5/135 plus ft/lbs, showing 120 ft/lbs as early as 2300 rpms.
This was in a Dyna!!

Scott,

I wish you'd stop telling us about all these wonderful rocket ships! Makes the more distant of us very envious.....

 

What would I do? well you have 30000 miles. Get the head ported, 1.9 intake valve, if you have 7mm valves replace with 5/16. prob. not a bad idea due to miles onthe guids, to have them replaced. Black diamond valves, new springs, seat pressure 140. If you have beehive springs check seat pressure if it is over 130 keep them and shave the top of valve guide. I hink those springs can be used with .640 and lower lift cams as long as the guide is cut down, but then again you do have a lot of miles on them and might beefit from newer springs.
Have your connecting rods checked. stock rods do not have races. Hell just get the 4-3/8 stroke have it plugged,trued, balanced and welded for $450 at revperf. If you want to use stock crank have them replace your connecting rods with h-beam or have them drill and race your originals(lots of options.)
lots of options on cams I like the wood555, but check with others that have used other cams. Looks as if you get the grunt and the top end with that cam.hear a lot of good things on Wood cams, just get the SE18404 adjustable pushrods to get rid of noise. replace your lifters. there cams are quiet just get a bad rep due to missadjustment or used lifters, from what I have read. bore jugs to next size bigger and get cast flatops. No need for forged pistons your not reving it past 5000 all the time. not to mension the flame travel will be faster on a flatop. put squish at .030-.032.. Change all the bearings in the bottom end if you pull the crank. No need for timken upgrade but the SE lefty is a good choice.
Might have 3k into build.

 

Update:::I rode down to T-Man spoke with TR....his recommendation...His stage II heads,tr625 cam,comp at 10:25:1....MY s&s 97" pistons/jugs,his cam chain tensioner upgrade....tune it and roll what do you guys think?????Seems like he didn"ttry to upsell me oh yea he said to use the stock harley B lifters.
