Need expert help upgrading my engine
I was going through SE catalog searching for REAL performance upgrades, but I got confused &\\; lost!! Dont know what to go for after finding many options for my 2007 Dyna!
 \\;
I'm looking for a kit that can offer good low-mid range pull, this is what I found:
 \\;
1- 103 stage 1 kit
2- 103 stage 2 kit
3- 110 stage 1 kit
4- 103 SE Pro stage 2 kit (high output)
5- 103 with 50MM EFI &\\; ported HTCC heads
 \\;
I'm leaning toward number 3, with the following configuration:
 \\;
Big bore cylinders, Twin Cam performance \\;heads, flat top stroker pistons \\;&\\; SE-258 cam
 \\;
 \\;
Any feedback or opinion will be helpful.

RE: Need expert help upgrading my engine
What are you after? \\; All out speed and power at any cost? \\; If so, aftermaket stuff will get you there cheaper. \\; However, if you want power and durability, I would stick with Screamin' Eagle, as you will still have a warranty. \\; SE compression ratios and cam lifts tend to be lower than aftermarket. \\; The trade-off is, of course, power...

IF cost is no problem then U need to call Kevin at Head-Quarters USA or Hillside cycle or GMR and forget about the SE parts all together!

HQ has 103 and 107 kits avaible that will give you 120+ lbs of torque and are Very reliable. These are not Race engines, just very hot touring motors that have a real big kick in the pants.
 \\;
Philm on the touring section just pulled 157 lbs of torque from his HQ 120 and just returned from a 3000 mile trip that he was averaging 45 mpg!
