Default 103 Upgrade for Torque

Ok guys I have a 2009 FLHTP (po po electra glide) I would like more off the line acceleration, especially when two up, and hill climbing ability. Right now it has a 103" motor and I don't have the budget to go 107 or larger but I do have the budget for cam, heads and maybe 2-1 exhaust. I have 4" rinehart slip-on w/o converters, S&S stealth ac and PowerVision tuner. Looking through the Fuel Moto cam shoot out (big shout out to Jamie) I have narrowed it down to the below cams and wanted input from anyone who has used these and what head upgrades you did (and dyno chart if you have it). Again trying to maximize torque from off the line to about 3500-4000 RPM range.
First Tier (Cam and Head Work and maybe .030" head gasket) S&S 583 or 551, Wood TW-222, Andrews 48.
Second Tier (future proof 107" or larger) Wood TW-777, S&S MR103, Cycle Rama 570-2
Thanks
Randy

FWIW.....

Those are all good cams.

However, for a true bolt-in cam, I've never heard anyone complain about the Andrews 48 cams. They have been a bolt-in favorite and have performed well for years...

They seem to work really well when added to Stage I mods (air cleaner & exhaust), without the need of headwork or a "bump" in compression. Of course, with any cam, you'll need a good tuner/tune to get the most benefit ...

Good luck with your decision..

+ 1 on the 48 I have a Hi Flo intake, a SuperTrapp, and a Andrews 48. A quiet tune got me 100 ft lbs at 2k rpm and 109 ft lbs at 3400k rpm. Hard to beat that.

Get some103CI SE pistons that will boost your Compression ratio to 10.5:1 with your stock heads, and drop in some SE 259e cams, and that should be all you need

I have limited experience but I did a 107" build for a guy on an 08 street glide using the 777's. Used fuelmoto for the parts and power vision tune. I know you have a 103 but it can't be far off a 107 with a similar setup...but really you're only around 700 bucks extra from going to the 107. Anyway that guys bike runs awesome, that combo from fuelmoto is very well sorted out. He had some electrical issues to get straight and I don't do electrical work very well so he brought it to a local indy and even that guy said that the bike is an animal lol. Honestly...if you have to wait a little while to get some more money in the war chest. I really think you would be really happy waiting and going for the big bore.

Instead of a 2-1, I’d recommend using that cash to lower your gearing.

Andrews 48. Great torque and drivability. I activated the ACRs on mine (2009 ultra) with a power vision tuner. Use good quality lifters, and I think you will enjoy your ride.

When I had my 103 I did heads , pipes , Cycle -Rama CR575 cams which don’t require bumping your compression and that motor was a torque monster. Call Wes at Cycle-Rama. He makes great products.

Have the Woods 222's on my Low Rider, are a great cam for low end and also give better top end than stock without having to raise compression.

I have the 551 cams and am very happy with the power for two-up riding. Especially in the mountains. Instant 100 plus foot-pounds of TQ before 2,000 rpms.
