Doing a 103 engine for my 04 ultra. Need info on the different stages 1 through 3 - 4 ? and what parts each consist of. Engine is done but not installed yet, So if I'm going to build it a bit more now is the time. I'm pretty sure I'm at stage 2 now. This is my build as of now, Everything is SE and NEW. Forged SE stroker crank {trued, balanced, welded} - cast 103 flat top pistons - 103 plus heads w man. com. release {cleaned up ports} .030 Cometic steel head gaskets - SE Forged rocker supports - SE roller rockers - SE billet hyd. cam plate kit - SE 255 cams {machined to work with the smaller inner needle bearings} - SE late oil pump - SE tappered adjust push rods - SE stage 1 cleaner - D&D fat cat 2 into 1 W quite Baff. T Max ECM w auto tune. Baker DD6 trans kit. I'm looking for low end torque, Don't care much about racing or beating anyone, Usually two up touring and a small trailer sometimes. But can anyone Give me an Idea as to what kind of numbers I can expect from this build or anything else to give it more grunt. I don't want to bore cases or change the jugs again so 103 is it for now.
