The bop belt drive is the bomb. Very nice piece and easy to manipulate Cam timing to your satisfaction


Just make sure you have plenty of valve clearance for the changes you want to make

Better yet, move it while running. It's all boxed up now and stored away- straight-cut gears were too noisy for my resto-mod GMC. On the test stand it showed promise- cam advanced nine degrees (crank) below 4,000 RPM improved throttle response and greatly improved the idle of a very "lumpy" cam. Next time I build a V8 Pontiac I'll look at converting it to helical gears- if i can concoct a compact scheme for containing end-thrust of the idler gear.
