Thanks
I`m not suggesting anything, again just a reference point

I guess what I'm asking is - will l get more TQ/HP with the 10-1 comp pistons and the bigger cam than I'm already getting with the bolt in EV13 in my stock motor?

Yes, you will. But the question you likely should be asking is whether or not the torque and HP will be available at the RPM's you ride in. Not just how much more power is it going to make.

The components you select need to work together, but also meet your needs.

"The OP is in Australia so this ^ may come into play" Agreed. That's why I mentioned fuel availability and ambient temperature. All these things should be considered.

Yes, we have access to good fuel where I live.

I had a friend of mine that had a Road King 80" all stock that he installed a set of Screaming Eagle heads on that bumped the compression to 9.5:1.. With that he went with the V-Thunder EVL-3010 cam and I must say I was very impressed with how that heavy bike got up and booggied and maintained with little effort... So if you're going with 10.0:1 compression and still want to have good torque and good power I would think the EVL 3010 would be the best choice especially with stock heads in a heavy bike.. The thing I like about the Woods cam is that it has earlier cylinder fill with higher TDC numbers which does make a difference.. I ran it and I thought it was awesome but that was in my Fatboy not the heavier Road King..

Agreed. So my question is will l get more TQ/HP with the 10-1 comp pistons and the EV46 / EVL3020 cam combined components than I'm already getting with the bolt in EV13 in my stock motor?

Just want to make sure it's worth the $$
Cheers

So it looks like from what you're suggesting, you can't beat the Woods cam at 10-1 for overall performance?
