I do a lot of S&S crate engines, here's 1 I just finished up.

S&S 124" LC crate
SE 58mm TB - 5.3 inj.
SE stage I A/C (I milled out to fit the 58mm TB)
Fatcat 2:1 (Perforated baffle)
Barnett +1 clutch, SE heavy spring, AIM 95 lock up

I have the same build on another bike that th owner is putting break in miles on, He's running a Dragula I pipe, I'll post his results when I get it tuned.

 

What compression and what cam...?

 

This is the S&S crate 124". S&S 585 EZ start at 10.2:1 compression. In my opinion this is the perfect touring engine.

 

God those lines look nice on that LC engine. My biggest regret was not doing the LC on my 03 RKC when it was time for a rebuild.

 

Here's the
comparison.

Red line is the 124" LC crate with the Dragula I pipe
Blue line is the same crate with the Fatcat

 

Wow, that's quite the difference at 2500 rpm. Basically 12 tq and 10 hp. what model draggle is that?

 

Dragula 1 with 2.55 baffle

 

I looked online for that pipe and can not find it. Can you send me a pic and a part# Thanx...Bob..

Not too pleased with he low end of my RB lsr. My old pythons staggered duals out did the 2-1 up to 3k...

I'll get a part number tomorrow. It's bowhunters bike and is on it in his signature picture. Dragos has a Dragula II out now as well that would possibly work even better
