Dont get caught up in all that nonsense....
Just more $$ to try to control harsh web cam profiles.....
We went through this 2 years ago and it seemed everyone just had to have these large buckets.
Well that fad came and left and I dont think theres many who now run them....
I used giant cams much larger than the web cams they suggest using the big buckets for and have had no issues.
Reduced base circles really should'nt have all that much to do with needing big buckets. If anything, if you took the same size profile and one was a reduced base circle, the overall size of the lobe ( from center of camshaft to top of the lobe peak) would be smaller on the R.B. cam and is less likely to contact past the edge of the bucket.
The thing with reduced base circles is they can be a bit harsher if the profile already existed and they then cut the base circle down from there to achieve more lift and duration. It will make opening and closing ramps more radical.
More radical opening and closing ramps equal better power numbers but kill the valve train. The reasoning for that is you can get the valve open quickly and close it quickly so you can get more in and more out of the cylinder (more duration) but that pounds on the seats, valves, springs, even shims..... Along with more duration, bigger low lift opening #'s help in the power department.
