570 Gear drive
my local shop that i has a great rep in the area has been pushing for me to go w/ gear drive cams. i was debating it for while, well my buddy did it and wit hhis 96, 570's, power commandor and full exhaust it dyno'd at 100 HP. i rode his before and after and wow the differnce it made. looks like im going to set up a time to get mine installed soon. i know all the requirements that have to be met to run them i not looking for that whole explination again. or start a debate to use chain drive cams.
my question is; is there another gear drive cam i should consider over the 570? i looking for more power in the 2000-3500 RPM range. i think i will be happy w the 570 just want to double check my options w/ your opinions

I have 509's. Dyno numbers are below on my 88" (Stage 1). The increase in power is most noticed when passing or pulling a big hill with a passenger. It was a worthwhile upgrade to my failing cam chain tensioners.

The 570s would be great in a 103! You"ll have good power across the board. Yes they would like a little bump in compression, so you may consider putting in a 0.030 head gasket but that is really about all the 570 cam would need.
The 570 has been around a while, but that just means its proven to work well.
Good luck.
