If Frank is doing the work. Tell him what you expect and how you truly ride your bike. He will give you the right combination depending on your wallet thickness.

26 is fairly mild, 37 might be better with other work. I have 26 in my 96" and they do good but I am thinking of changing them and doing a bit of work... Like a 107 kit so the 26 will have to go.

I am going to do the screamin eagle hydraulic upgrade with cams for now.

Instead of the 25284-11 hydraulic upgrade I would go with the 25282-11 upgrade and then use conversion cams. There are a few reasons I recommend this. It does away with needing to buy the 25285-08 spacer kit, it does away with the outer cam bearings (that are not included in the kit) which have been proven to be pretty useless, you will use the roller cam chain and gears, and if you decide to go with different cams when or after you do the heads and bore it makes changing cams much easier. If you get much of a compression bump when you do the heads and bore neither the 26's or 37's will be cams for you. Both close the intake before 40 degrees abdc which determines your dynamic compression. The 54 or 55 cams will probably do better with higher compression. Frank is grinding some cams of his own design that may well work with higher compression. I don't know if he is considering doing them as conversion cams. By the way, Andrews puts an "N" behind the grind number on their conversion cams (37N).

Went with 21's myself, but i do a lot of 2 up and stayed with the 88 incher. 26's will give you the same pull, just later in the rpm range. My 21's kick in about 1700. 1 up and a bild would definitely make me lean towards the 37's or even more. Aggressive riding style calls for a cam that kicks in later and pulls higher into the rpm range. Good luck.

I did the Andrews 26's in my 06 have stage one V & H slip on's and tune with the Fuel Pac and my runs with stock 96 inch motors and if your not doing major eng. work right away that's a good combo
