to build or to let be

Sorry,but I'm partial to the /6 movement !! You can shave the head (I've taken .090 off mine,WITHOUT checking for piston to valve clearances and adding 9:1 pistons),get one of the above named cams (Comp Cam) and have fun at a minimal investment !! The 440 is going to require far more headaches all the way around !!! I was always taught to KISS it !!! Keep It Simple Stupid
