Cam Break In Procedures... #615797 02/17/10 04:10 PM 02/17/10 04:10 PM

I am currently building a 440 with eddy heads and would like to use a solid flat tappet cam " not sure yet of manufacturer" but somewhere in the .620 to .630 lift range. While searching for a cam I see that a lot of companys are recomending that during break in to remove the inner spring is this something that is has to be done or is this overkill. My springs are 145lbs @ seat and 380lbs @ 600 lift.

I am not an engine builder but have done 3 motors for myself and that is the procedure that I used and had no problems.

I bought most of my config from him including a.614" solid flat tappet using Hughes 1.6 roller rocker setup.He has a break-in oil as well.

I agree with this...we use our engine stand to break in engines so everything is easy access anyway, so installing the inner springs afterwards is a piece of cake. And we still use the break in oil and additives. With the large amount of wiped out cams you hear about nowadays I believe in overkill. Peace of mind and not having to clean metal out of an engine with a wiped cam=priceless.

If you pick one with a very aggressive lobe profile, there may be issues. A friend picked a cam with aggressive lobes and wiped it. Next time removed inner spring and broke in w/o issues. BTW same spring pressures as you. So I'd also be looking at high quality lifters as well. Just my take 5816909-2807897-belvy.gif (45 downloads)

I was just trying to get by with a little less work. The only reason I havent called Hughes is that I understand to run one of their cams you have to use their springs and my heads are currently set up with new springs.

Don't take the chance, do everything you can to avoid wiping a lobe/lifter during break-in. The results of a wiped cam is worse than the work to change the springs after break-in.

I'd recommend them as well, but it's really hard to write that check. I did and am glad I did. Not sure it's in everyones budget. 5816957-2807897-belvy.gif (27 downloads)

The lifters shouldn't be any different than stock lifters unless you have them custom made. Do you have more info on those springs? If your going with a cam with 630 lift you might put yourself into a coil bind situation and that will break parts and flatten cams. I know that the sm lifters are expensive but the cost of wiping a cam is triple the amount of the lifters and they are completely reusable on other cams. 5818614-Pictures-01.jpg (23 downloads)
