As stated, the computer reads lift & rotation only, then drops the info into the hard drive and generates theoretical duration, and open and closing events, all of which are measured in crankshaft degrees which clearly I don't have hooked to computer. ANY REAL ENGINE BUILDER KNOWS THE ONLY TRUE SPECS ARE WHEN THE ENGINE IS ASSEMBLED AND DEGREED. Camshaft centerline to Crankshaft centerline will vary with milling, decking, aftermarket head gasket, none of which can be " computed " with any accuracy. Degreeing this build set cam gear at zero and get your specs.
i think this basically states it all. for me i did what Bone stated with my ExoSpeed Stage 3 cams, but the i lashed my them to OEM specs and my Idle wouldn't drop lower than 2k. it wasn't till i received the proper lashing spec that i was able to drop my idle to about 500 rpm once warmed up.Install cam straight up, adjust cam gear, readjusting base ignition timing as well to get desired powerband.....
I tend not to overthink things
i didn't no degree the cam. we got it to TDC made sure when we tighten the the timing belt tensioner it would be on TDC.(this took some time) and with a small tune on the dyno and adjustment to the fuel maps i put down 135whp. it was the the start nothing more a base on where my engine will begin. nothing more nothing less. so as Bone stated put in and start somewhere.
