With jugs and pistons you wont be able to get to 103, the biggest I know of being able to go with a TC88 is 95ci but with the kit you can up your compression, gain more HP and more TQ threw the whole RPM range

I knew I wouldn’t get to a 103 but I was wanting more power and torque for.

Opinions on this??? Your reading comprehension sucks. Lol. Ill repeat... Unless youre going to split the cases the biggest you can go is 98 with a bore and s&s makes a 100" kit. A 98" with the right combo can be a very nice running motor. I think those 103 cylinders will yield you a huge bump up to 90" inch or so???...its all in the stroke...88"=4" stroke 96,103,110 twin cam is 4 3/8" stroke. Again if you want to go bigger than a 98 break out the checkbook

There is not one thing wrong with the S&S 98 incher. (if it is still available?)
My friend had one in a Softail, the high compression set up, and it was an awesome runner. This is a great solution with Andrews cams
Check with Jamie at FuelMoto, they have fantastic bolt-in big bore solutions. I love mine.
