John Simpson FE Rockers
Solution...leave as is for now...10/22/02
Thanks George!
I now know much more about my 428 than ever before.
Sort of makes you wonder how people got along without
the internet and digital cameras!!
In short, it doesent appear that adding roller rockers
will do much other than give me somthing to do. If I
do ever plan on making any cam changes I will most
likely go with your shop for parts and help.
thanks again
