Best cam for 88b heritage
Hi I have a 2002 FLSTC with 60,000 miles and a33 tooth drive pulley. I am thinking of replacing the stock cams with something that will give me some low end power. I previously replaced tensioners and cam bearings but did not upgrade to screaming eagle hydraulic cam chain tensioner update plate kit. (is it necessary?) I don't want to open Pandora's box because the bike runs great. I have to replace the rocker boxes because of pitting so that's is what is getting me to think of this upgrade.
Any suggestions... Get a newer heritage? My 2002 has better lean angles than the new m8 and is lighter. I would consider a 96ci or a 103 with ABS please give me your opinion.

Sorry but unless you've altered your susp, your 02 does not have better
lean angles than the new Heritage.
I have 203s but doing it again, I'd go a diff route. Something
with more oomph.
Any thing is better than the de tuned EPA cams that come
in em.

If you're gonna keep your bike, and want some low end grunt... Can't beat the Andrews 21 cams in a stock 88ci...
Whether you decide to stay with the spring tensioners (TW-21 cam), go to the upgraded '07+ cam plate (21N cam), or have acceptable crank runout and want to go with gear drive cams (21G cam)... there is an Andrews 21 cam for your application.
Sure there are other cam choices, different cam profiles, and different cam power band attributes... but there is no denying there are many happy 21 cam owners....

I installed S&S 509 gear drive cams. The increased power is wonderful and the exhaust note changed due to the overlap. The stock cams back then did not have any. As the Andrews are good as well. All I can say is change them and enjoy.

Best cam for 88b heritage
Thank you all for your reply's. I was wondering if there is a big advantage to the upgraded '07 cam plate. Is it worth the $500?
Also I double checked the specs on the lean angles 2002 Left/Right 28.7 / 28.9 Ground clearance 5.1 Dry weight 695
2019 Left/Right 29.5 / 27.3 Ground clearance 4.7 Dry weight 697

Yes.... there is an advantage to the upgraded '07+ cam plate. The '07+ cam plate upgrade, while requiring the purchase of conversion cams, will give you roller chains on both the front & rear cam gears.. you will then have roller chains rubbing against the cam tensioners instead of a link chain.
If you just replace the tensioners you will still be running two link chain cam chains. If you go with the Screamin' Eagle cam plate upgrade, you will still be running the OEM link chain on the rear cam gears.
The link chain is part of the problem with wearing the cam tensioners. When the MoCo switched to the better hydraulic tensioners, they also switched to roller cam chains... big improvement.
Since you have an '02, you could very well have an acceptable crank runout measurement, that would allow for he use of gear cams... Obviously, gear cams are the best cam chest upgrade... absolutely no worry, ever again, about cam chains or tensioners.... BUT, you need to have a crank runout of .003" or less, otherwise the cam gears will eventually self destruct... Not all engines will be able to go this route...

I did the same. Went with S&S adjustable pushrods and S&S lifters too. Kept the stock cam plate. No more tensioners. Bike runs awesome. Noticeable bump in hill climbing grunt.
