Installation Time: Full Day
May 12, 2016
I would make this your last upgrade on a full bolt daily driver GT beings horsepower gain is small vs the cost of cams and install time. Yes the cams have a nice choppy idle, shakes a bit at red lights and if you’re buying these for the sound then they will hit your target however they claim you will not lose any low end power and I found that to be a little misleading. While they do add what feels like 15 to 20 horses they seem to zap some of the low end (below 3.500 rpms) response out of the motor and it defiantly losses some grunt down low and I noticed this with 4.10 geared/manual I can’t imagine what a stock geared auto would feel like. You will want to crank in some timing advancement on your tune.
Take your time on this install and expect some major lifter/lash adjuster taps on first start up but this will go away during warm up if all went well also make sure you order bolts for the cams (uses same size bolt as harmonic balancer crank pulley ford or feeBay has them) on the Romeo motors and order gears too if you have a Windsor motor.
Don’t get me wrong I am enjoying these cams and they do pull noticeable harder from 4k to 6,300rpms but if you’re still running a relatively stock GT there are other upgrades that will yield nearly the same gains, cheaper and easier to install. Because of this I say get gears, handheld tuner, plenum, 75mm throttle body, under drive pulleys, full exhaust and such first after all that if you want more (and you will) then cough up the extra cash and buy these as they will be your last upgrade on a N/A motor stock block.
This gets me to the point of cam choice. As temping as it is Do Not go for the stage 2 or stage 3 cams if you plan on keeping the motor itself stock and not building a race motor and here are some reasons why. First this is the only cam that you can use the stock valve springs if your motor is still healthy, this is the only cam that you won’t have piston to valve clearance issues, this is the only cam that can run on a stock tune but also can be tuned in great with a simple handheld tuner, other cams have major idle issues that will need to be worked out, any other larger cam will not make you faster than these on a stock block with stock heads and intake manifold. By going larger then these on a stock block you will just simplify lose drivability and have tuning issues to say the least.
Bottom-line… Good cams. Sounds good. Runs strong. Price per gain hurts some. Will make you smile if you did all other bolt-ons first and ran out of options.
