Alright, ive been trying to find out everything i can about this freshly rebuilt small block thats in this camaro i just bought, the guy sent me a fact sheet of everything that was put into it and all the work that is done, i just ran into some stuff i dont quite understand, if anyone could please explain in the most simplest words possable that would be great... Basicly, i want to know if its good, or bad.. lol and a breif explanation of what exactly it means.
This is all from a 350 small block bored .30 over...

Duration @ .50' 230/230
Gross valve lift .480/.480
Love seperation 110

What exactly does all that mean?

 

Those are the camshaft specifications.

 

I was hopeing so, ive been looking for the info for awile now...
Now.. in your simplest words.. is it good or what for a "high preformance" 350

 

It's a comp magnum 280H I think...?
A pretty good cam, not perfect, but pretty good. Depending on the application of course.
I'd point you to a tech article I wrote on camshafts, but it hasn't been posted yet...
