I have a 2003 Dyna Wide glide and I am looking at changing the cam.

My motor is stock although put on Vance & Hines Big Radius exhuast and I have had the carbarator jets ported and have changed the air cleaner to the screaming eagle filter.

I want to change the cam for two reasons, one for better performance and secondly I want a better sounding bike. I also want the motor to have the good loping sound of a Harley.

75% of my riding is in the city and 25% on the highway. I want a bike that is drivable at all speeds & rpm's. I was told to go to a 303 or 304 cam.

What are the differences in a 303 or 304 cam?
Will I get the performance I am looking for and the loping sound I desire?
If a 303 or 304 cam isn't best, what do you recommend?

Thanks,
JJ

 

Those cams numbers should be 203 and 204.

 

I had a typo, I'm looking at 203 or 204 cams.

Don't know if you're going to get the potato-potato-potato sound you're looking for by changing your cam. I think you'd have to drop the idle to dangerously low levels to get that effect.

I would think the cam would have some affect on the sound wouldn't it?

The cam in my bike is .5" lift, 240-deg duration, 102-deg LSA and I don't get the lope (potato-potato) you're referring to unless I set the idle dangerously low.

If your not going to do anything else to the motor , the 203 and 204 or ok, I'd consider the Andrews TW21 or TW 26 instead though. I'm running a TW31G with my 95 and it has a nice cam lope sound., but I got it for the grunt.

 

203's will give you better low and mid rpm performance and a pretty lumpy idle with stock heads and compression ratio. They have quite a lot of overlap (35 degrees) for low end cams, hence the poor idle quality. Torque starts to fall down at 4k rpm, but most folks don't spend a lot of time up there anyway. I have 203's in my Wide Glide motor and am happy with the performance. They WILL make your exhaust louder, also. If I was going to do it over, I'd go with Andrews 21's or 26's for performance.
Changing cams should be a performance thing, not a sound thing.
