So im over my crow 2549, ive been looking at different cams and think that the 1521a would suit what I want. Can someone please tell me what lsa means? Because Ive heard that 114 lsa is no good and I should get 112 lsa

manual or auto? LSA is how close the lobe centrelines are to each other, generally closer together is more overlap/lumpier idle, narrower powerband but higher peak power

Manual, I want a lumpy idle so I would go with 112 lsa?

It turns on nice and early but I'm after more power in the top end, my ticky head is also ported with big springs and 30 thou off |

haven't given it a good run yet, but feels like it comes on about 2600. and I can raise my limiter if need be

Is your rev limiter raised? its raised to 6300rpm, it comes on hard as soon as you touch the throttle all the way to the limiter. my bad just realized that was for ranga83
