Is head work on the new engine all you're doing to it out of the crate? Have read others saying the initial cams weren't ideal either. I never ran the specs on one of those engines though so really had no idea how much was accurate and how much was a continued case of dollar-itis.
Two weeks more of withdrawal? You gonna make it?
Twolane,,, Last October I started a project to upgrade cams to a set of S&S 640 gear drive cams in my Jims 131, which i've had for a little over three years. Once i got the cam cavity opened up i checked the run-out and measured 14/1000's,, Not good
. Since the motor was slightly over two years out of Jims warranty i called SB Charlie to arrange getting the motor to him for a complete rebuild. Charlie tells me that Jims had a run of bad cranks during the time i purchased the motor and suggest i contact them to see what they would do for me. To my surprise Jims said they would cover the rebuild at no expense, other than shipping cost and labor to install (which i did). Now that i have the motor back from Jim's, the heads are going out to Charlie for a CNC valve job and minor porting since the Jim's heads are already CNC ported. He will also set the heads up for the 640 camshaft. Along with the cam change I will be adding a Fueling oil pump, Fueling cam plate, Woods directional lifters and Smith Bro's push rods. If all goes as planned i should have this up and running by mid February, broke in and ready for our anual road trip to Death Valley in March. Sending the ECM off to Rev Performance today and looking forward to seeing how well she runs with this setup, which is a big relief since i dont have to hassle with a dyno tune.. The Death Valley trip will defiantly be a good road test for the EMS.. and your write up will help me get through this install.... more to come...
