new cam
Hello im in the process of replacing my cam with a Andrews #2 grind low compression cam and was wondering what others had to do. I got andrews collars for spacing the valves and know about case clearence just wondering what else might be needed. Thanks craig

Not an Andrews fan myself, had issues with their cams too many times over the years and they have a lousy power band, you need to get up to 2500 rpm or more before they come on decently.
Sorry, all I got for it.

I changed from a stock cam on my 2003 fxdwg to an Andrews 26 cam along with bearings, tensioner shoes etc. and have been quite pleased. I did it to increase torque and have no complaints. The power band begins at 1800 and runs through 3500-4000 RPM.

His is a shovelhead, completely different animal than andrews for twinkies.

Well, I am in the process of building a bike using an Andrews #2 cam. Although based on advice from others on this site I will be running it at 9.5:1 CR rather than the lower numbers it is intended for.

Hopefully it will go well...
My engine builder is doing all the motor work, so I can't really help you with what needs doing other than making sure the valve guides are machined properly and clearances are all good.

Andrews may have gotten it's **** together, I quit using them a long time ago so my info could be a bit dated for them.
Good luck on the builds and please keep the feedback up when you get some riding time in .

What compression are you running that at? I as well am going from an Andrews A cam to a #2 But the difference there, is only 8* ivc. your cam swap was 17* That's a huge difference...
