Reply to "Bullet Cobra Jet Cam"

Installing a cam slightly advanced is only significant if you also install a brand-new cam chain. Normal wear on a 351-C chain soon retards the cam while running, which is the main reason why some cam grinders specify installing their product a bit advanced. Cleveland chains wear faster than normal due to the large heavy valves, so on an older chain, you may not need the fiddling required for an extra 2 degrees advance. If the chain has over 5000 miles on it, your engine likely could use a new one.

As for more LSA, as you know from your reading it maximizes power, raises where maximum power & torque occur by a couple of hundred rpms (up), reduces overlap of intake & exhaust valves and increases vacuum for your power brakes. A hot engine may idle smoother with less chance of knock (more significant with iron heads than aluminum) and crank over a little easier (if you don't have a hi-power mini-starter).

Mike at Bullet Cams knows his products which are well respected and do not exactly compare to other brands, and in any case the difference in LSA from 110 normally only varies max horsepower by 3 or 4 in a 500 bhp engine. Is this cam a hydraulic roller? They behave a little differently than a hydraulic flat tappet.
