I would like to know how this cam is going to act in my 425. Is this similar to a stock cam and what engine would have used a cam similar to this?
Thanks in advance.

 

I'm not an engine, guy, but, that looks like a fairly mild grind.
I posted mainly to mention to make sure this cam will work
with the bank angle of your engine-39 deg. or 45 deg.

 

Pretty small cam for a 425, would be a bottom end torque monster with no top end power. Decent cam for a mild 350.

 

Other than the higher lift, that doesn't seem too different from the cam used in the base 350 motors. That's pretty much an "RV" cam in a BBO.

 

Will be used to bake the tires on my toronado.

 

May want to make sure it's not too high of compression, you'll likely want to be running premium, likely prone to pinging on hot days when lugging around.

One thing I forgot to mention is that I believe Engle rates their advertised duration values at 0.008", rather than 0.006" (comp/bullet) or in some cases 0.004" (crane I think). Therefore, the Engle cam will look slightly smaller than others due to the way they rate it.

 

Paul, I used the jm 18-20 cam in my 425 and it performed well. Nice idle and plenty of low end torque.
