I did look at the S&S crate motor's along with SE 120's but they are not going to be tailored to my needs and not built as well. I think for the same cost I can build a balanced 124" engine for the same cost as a crate and it will make better power. Too say I'm not going to run the new combo hard would probably not be a true statement this Is why I'm doing the work to feel some performance plus I do allot of wrenching myself which helps with cost. I don't think the stock untouched crank would last very long at 130hp running it hard and why have that much power and not use it. I was planning to chatting with Darkhorse for the crank work I think they have their line of nice cranks so I'm not dead set on S&S at least in stock form.

This comment is unsubstantiated. Let’s find one post of a twisted late model crank putting out up to 130. Riding hard won’t do it, using all the power won’t do it, above and beyond abuse might get it to move but maybe not. A stock motor could bung up a crank if lugged then WOT for example with regularity. I’ve done a dozen builds ranging from all out 107s to all out 124s and 131ci. The 107s were beaten on every ride but with shock loading avoided, full rpm use but keeping the instigation of horseplay above 3200 rpms. Don’t let the myth of cranks imploding over 120/120 cloud your decisions. Build the 124 by all means, just be prepared if using even your existing cases the total cost will run 8-10k with all the peripheral components you’ll need. As djl has mentioned you’ll use nothing on the bike now unless you have the right pipe. Clutch, intake, injectors, tbody, tune, larger oil cooler, roller rockers, camchest.....and possibly more if done right.

You are correct I only know what I read on the stock cranks but lets say I do a 107 or 110 kit on that and it grenades then I'm back in the same boat. I'm not new to building things and know power comes with a price tag. I do know if I was to build from scratch it would be very select parts on a well balanced bulletproof lower end yes it may cost 8K but I think it will be better than you could buy crate motor wise plus tailored to me.
Don't take me as cocky I did ask for help here and it will all soak in before I make up my mind and greatly appreciate the wisdom that comes my way.
Let me ask are there any weak spots in the 124 S&S crate engines? I know the SE 120r has crappy lifters and heavy valve springs but if I could get into one of those without needing to swap too much out I will consider that route.

Is this the kit they would use to build the crate 124 ?

I had a 110" build done on my 103". New cylinders, pistons, cams, TB, injectors, clutch, etc... Total out-of-pocket cost with tune approx $6k and I did none of the work due to personal time constraints. 126 ft-lb / 122 Hp. Didn't touch the bottom end. Ran it hard all summer, no issues so far. Perfectly happy...

2. You could go that route but would still have to send lower unit to Darkhorse for case boring and Timken conversion which will cost mas o menos $800 and another $165 if you want the crank plugged or $30 if you want it welded. As I said in #1, I did not see a cam plate/pump in the linked kit and would definitely not run the OEM cam plate in a 124" motor and might replace the oil pump; more money. Why not throw another $500 at the project and get an assembled motor?

Sorry if I was vague but I was just trying to figure out what exact parts are used in the T124 crate engine and was just assuming that kit was the bulk of it. I did not plan on adding it to my engine.
The S&S crate 124 comes with their TC3 plate and pump just don't know if it has a Timken bearing setup.
