257 Cams
I have a 1999 Dyna twin cam 1450, when i brought it, it came with a box of 257 cams. Can anyone give me any advice as to what I will need to change install these. I understand I will need SE adjustable push rods and SE Valve Spring Kit.....not sure what else i will need??
Cheers

Those are not bolt in cams. You ideally need head work and different pistons. That cam wants more compression than stock. Without doing that, they will give you worse performance than stock. It is more of a higher rpm cam. Stock 88" can only go with a .510 lift cam. Even changing springs doesn't really help because the factory compression is only 8.8-1. When you factor the corrected compresion, it goes down. That cam probably wants a 9.5-1 corrected compression to be ideal.

I'm in the process of putting 257 cams into my 2002, here are the parts needed to make the cams work properly.
Cam Plate HD25284-11 $499.95
Spacer Kit 25285-08 17.95
Inner Cam Bearings 24017-10 14.95
Push rods 17997-99A 127.00
I paid $625.00 for those parts, looking around different places.
You might get a better deal, these are retail prices but you need all of these parts.
I bought new jugs and heads from a friend who went with bigger stuff, paid $150 for those
You will need to re-map the ECM afterwards.
