After recovering from the shock of the $310 price tag on an RV grind cam from Man-A-Fre, I decided to go in search of a camshaft grinder that could beat that price on a custom bump stick.
Racer Brown of Baltimore MD phone (410) 866-7660; has ground a variable duration RV style cam for our FJ40 with the 2F engine. For you techies that crave info here it is.
Lift .417" at the valve on both the intake and exhaust with the 1.5" (stock) rockers.
Duration of Intake:
at lash .004" - 258*
.005" - 256*
.006" - 254*
Duration of Exhaust:
at lash of .018" 244*
Duration @ .050" 206* on Intake and Exhaust.
Lobe centerline intake 106* exhaust 114*
Lobe separation is 110*
This is a fresh billet ground and Parkerized by Racer Brown cams, not a regrind!
Cam is designed to have more torque and horsepower from idle on up, with good vacuum for the power brakes. The factory cam runs out of breath at 3300 rpm on our
vehicle. This cam is designed to go to 3900 rpm. Even though the 2F is basically a tractor
engine modeled after a Chevy straight six, this cam should make merging onto the freeways a little safer.
Best of all two custom ground cams; one for the 340 Duster and one for the FJ40
(mixed marriage) with shipping were under $300.
Turn-around time is usually two weeks.
Once the cam is installed and I have a chance to run the vehicle a while, I will post results of the "butt-o-meter" Sorry, I have not received my Dynomometer from Santa yet.
