Mat,
David Vizard's book has already been suggested. Why don't you have a copy
yet? The selection of springs is not simply a function of the desired RPM
range. The stock springs might suffer from coil binding at the lifts
provided by a modern racing cam, especially using high lift rockers. This
would have a negative effect on the ability of your engine to produce RPM,
torque, or horsepower. The purveyor of your camshaft can make valid
suggestions as to suitable springs for your intended usage. The selection
of valves is also not just a choice of material. READ VIZARD. When you
have finished that, READ VIZARD. Then, just to get some new insight into
this READ VIZARD. Don't waste any more of your time or money until you have
READ VIZARD.

....I dont know but I have been reading up on camshafts,
I was wondering if anyone knew the advantage of a "scatter pattern" cam? I
have one in my bug right now, and with this new motor we are building, we
are looking for the best cam for our needs... power from 4500-7500rpm. Any
suggestion on a cam?
Anyone have a suggestion for a good A series 1275 book? I have Des Hammills
book but its just info, doesnt give any inside info on which parts to use,
just suggestions on good street motors and what is neccessary to have not to
have a meltdown of a race motor...
