40 rwhp stock 1992 xl, $4000.00 and now 120 rwhp . That's about 50 bones per hp.
Not bad for 1.58 hp per cube. That means a 120r would need about 190 hp lol ��
Just curious of which Chris Rivas cam you went with and how you like it?
Ok, this is weird. I answered the question several days ago by logging in on my phone, (on the road), and the answer isn't here.
I got the 574, and I love it!
It's not just a torque cam, and it's not just a hp cam, it's a great combo of both. It pulls strong all the way to 5k+, with no flat spots.
If I'm behind a truck, doing 60, and drop back just far enough to make sure I can see his mirrors, drop it into 5th, even though I absolutely don't need to, and roll it on, I'll pass the cab doing 100.
Considering the motor is still bone stock other than the cam, it's a beast.

Comments: This is a pump gas street motor with all bolt-on components. It's also rev 3 of Ryan's motor. Last year he "only" had 115hp. A few updates to his stuff, an excellent job of screwing it together, and a good dyno tune netted him the above chart."

Dam!! That's good to hear although I have a 13 streetglide I guess in 14 they changed the cam. But the shop I'm taking it tomorrow mention the S&S 551 or the Chris R 574 which I never heard of and was looking for some feed back. So 574 has good low end torque? I know you already described it but it look like not to many riders have that cam. I might just pull the trigger and tell them to install the 574 cam.

Chris pulled all his cams off his web page because of the CARB/EPA risks. But, Drag Specialties carries his cams, and they're in the Fat Book:
My charts. Chris uses STD correction factor instead of SAE, so the true numbers are probably closer to 100/105, but still... Oh, and don't underestimate how much the Pro Pipe helps. If you have 2-1-2, or even worse, true duals, you won't see these numbers.

If you look at the cam specs, it's reall close to a crane H290 advanced 4 degrees. It's a good cam but I would still consider it more of a mid-range cam.
A 2-1-2 probably won't give you the same TQ curve as posted. I used a 290 adv 4 in a 88 ci Evo.. Ran real well but ran staggered duals.. Also ran a set in a 02 TC 95 ci bagger (10.8 to 1) straight up and it ran real strong with a Fatcat, kind of weak on the low side with TDs but better with a Kromeworks H pipe.
