Timing Gear Drive

i've been thinkin about a gear drive in the 360 i'm putting in the scamp , won't be a huge power maker, i'm hopin for something like 350-400 hp but i love the sound and realiability compared to a chain. does anyone have the link to these CAT gear drives?? i can't seem to find them. don't really have the $$$ to dish out for a milodon
