Those are correct numbers with the mods as is. But with the new mods awaiting install, I am hoping for close to 300fwhp. New mods include - SHM headers, Stand Alone Engine Managment system, a intake of some sort (still using stock intake) optimized TB 62mm and completely remove the secondaries (haven't decided on that yet.) The last dyno, my peak numbers were right at the fuel cutoff, so we are hoping to get about 10 more hp just by raising the rev limiter, and hopefully 10hp from the headers and an optimized exhaust for the engine (currently running Borla single exhaust). With some good dyno tuning and a few other things, I am hoping for close to 300 at the wheels, but I will probably end up in the mid 280 range. Plus, I have to find out what the correction factors are for the higher elevation (it's not that high, but over 2000 feet) that might get me an extra .05 hp, but hey everything helps!!! 2001 Mercury Cougar

Brad, in reality the timing chain is a extremely stressed component in the engine. True, there isn't much resistance from actually turning the cams. However, I know you timed your engine and you must have felt the large amount of torque needed to open the valves by turning the crankshaft. (and no there isn't much compression resistance when you just turn the crank a few degrees to line up the chain) In addition to the above, the chain is subject to large torque pulses as each cylinder fires and applies torque to the crankshaft. The damper and flywheel do provide some help but it's still not an easy life for the chains. Still, I have not seen any issues in my experience with the Duratec timing chains (small or large size). I would have to guess that PuckPuck's failure was due to some other cause than an inherent design flaw with the smaller pitch chain.

On a 2.5L the LH head cam caps will be numbered 1L, 2L, ...9L. The RH caps will be 1R, 2R,...8R. LH head has one extra cam cap on the intake cam for water pump drive. There are no measurments stamped on the heads.
