88 cam swap
So Im planning out my engine upgrades for my 06 dyna 88. Ive seen a lot of good things about the andrews 48h cam and was thinking of going with that. I want to later down the line upgrade the jugs to a 95. Would the 48h still be a good match with that?
Also what other things should I upgrade while Im in there? I heard about adjustable pushrods and cam plate, anything else?
Majority of my riding is spent in the 2500-4000 rpm range as well, occasionally 2 up.
Also the bike was bought with true dual python exhaust and has a SE backplate and air cleaner with the stock cover

The stock pushrods can only be reused if the cams have stock base circle diameter. I don't know if the 48's have that, I know my Andrews 55 cams do not.

48 base circle is .020" smaller than stock. Some retain stock pushrods with the 48s and some get some valve train rattle around 2800-3000 rpms and some don't. Dealer's choice IMHO but considering factory tolerances, if funds are available, adjustable pushrods can be adjusted to address valve train noise. A set of Johnson Hy-Lifts from WFO Larry should also be on the parts list. If the OP waits to increase displacement, using a .030" head gasket will take up the .010" diffefence in base circle with stock pushrods. Why stop at 95" when 98" is available for the same cost?

Yes that is what I am saying. Other cam choices notwithstanding, the 48 will work fine in a 98" configuration; stick with flat top pistons.
