Can anyone inform me what these cams will do for my Heritage? Thanks, Brad

 

We need to know the rest of your build to give you a good answer. Those cams work good with 95" flat top pistons 9.5 to 9.8 cr. With a good exhaust, they should give you
95-97 tq and 85-87hp. With headwork, more. If you're putting them in a stock 88", they may be a little soft below 3000 rpm, but should get you 90 tq and 80 hp above that.

 

What about on a 2003 dyna lowrider...the mackie tc510 looks like a great cam..but my bike is light....i hear goods things...how will it do on my 95" build with no head work, se flat tops...

 

After alot of research, i went with the mackie 510 on my 2003 lowrider
95" build....with se ignition, se air, 42 mm mikuni carb., vh big radius exhaust...love the build, and the cams are great...seat of the pants great..
Pulls from idle thru....really pulls if you get on the throttle..wow
