[QUOTE="swampratt, post: 3220625, member: 15054"] That is the idea the earlier closing of the intake valve will build more cylinder pressure and help the low compression engine make power Low as in under 10.5 compression. Yea I am not afraid of compression. But the duration should carry the power on up as will the overlap. Need all we can get to get the heavy truck out of the hole. He came to me with a TURD of a truck 210 or 200 cc china heads and a comp magnum 305H cam. That cam does not have any of the advance ground into it and was installed at 110 intake centerline. It was a turd everywhere and would be lucky to run 20's in the 1/4 mile with his 2.75 gear. His total timing was a 22 degrees when I first got my hands on it. the PCV and power brakes were T together.. this was a mess of a set up under the hood of his truck. Sounder really mean though pulling 5.5" of vacuum. Edelbrock 750 metering rods and power piston would not pull down at idle. just a huge mess. This thing will be a beast compared to what he had.
