Bit technical on CAMs

Anybody got any good reading on changing from hydraulic to solid cams? My 76 302 needs a cam and all I have is the solid hipo cam.

Re: Bit technical on CAMs

Hmmm. Changes.

1) Lifters. (that's rather obvious)

2) Adjustable valve train. (to facilitate adjusting the valve lash)
I'm guessing your current rockers are "pedestal mount-positive stop" type. (Torque the stud nut on all the way. No adjustability.)
You'd need to get some self locking nuts. Like these, or these, or this kit if you have 5/16" studs.
I'm also guessing, your rockers are the "rail type". (They have “ears” on the valve tip end of the rocker where it contacts the valve.)
Not recommended for hi-po use.
However, they could work with the adjustable nuts, if you had to do it that way.

3) Valves will need to be changed.
You need the type that have a .250 hardened "tip" on the valve stem.
If you use the stock valves, with solid lifters, the rocker arm will hammer the tip, and........boom! [img]images/graemlins/shocked.gif[/img]

Unfortunately, it's not a quick and easy swap from a hydraulic to solid cam.
The best way by far IMHO, is to mill the stud bosses, and install 3/8" studs and guideplates.
Get the newer style (non rail type) rockers, or better yet, especially with a solid cam, rollers.
Hardened pushrods will also be required, if using guide plates.

Here's some related reading.

Re: Bit technical on CAMs

Didn't want to do all that work to get the solid in?? [img]images/graemlins/tongue.gif[/img] [img]images/graemlins/grin.gif[/img]
Don't know off-hand whom may want that cam in this area, but I can check.
What are the specs?

Sounds like you made the right choice, since the hyd cam was cheaper than all the mods you would have to do.

Re: Bit technical on CAMs

Hmmm.
"Big um" top end cam.
Not for your average off-roader.
In your Mustang though....... [img]images/graemlins/burnout.gif[/img]
