Check My Cam Degreeing
How do you figure 114 is straight up.............. is that a 114LSA cam? Do you know that for sure?
At your Scr, your pressure is gonna be approaching 175 psi or more; can you run that with iron heads?
I did compression check before I took it apart. They were all between 145# and 155#.
OP, what model of KB piston do you have? Something is missing from your static CR computation. Is this an LA block?
Any way that you had the crank sprocket at the -4 position, and moving it to the +4 position changed the timing by 8-10 degrees. Something like this might be going on. Sometimes the little stamped geometric shapes that designate the timing keyways are hard to read.
I just looked back at post #12. I typoed the dome volume. According to KB's site, it should be -1.2, not the -.013 that I typed. I still get the 11.82. The .035 gasket thickness is a guess. New they're .038.
I have no idea if they were milled. They are 915's.
wade through this one
it will tell you what not to do
then how to do it
Degree an installed/unknown camshaft
Didn't finish it yet. Some of it made my eyes glaze over! Good stuff though, thanks.
In addition to checking TDC as in post #6, today I used an indicator on the top of the piston. Same results.
I rechecked everything again today, using YR's method and Chrysler's. I still got 113 w/ it advanced. I returned it to "0", and I got 108 twice. I'm good with 108. I'm pretty sure the tip of my indicator was dragging on the side of the lifter bore. I'm not sure what happened when, but that's why I'm checking over and over. Each time makes me more comfortable with the procedure. I think I broke in the rings already!!!
I have indicator extensions on the way. I don't think they'll show any difference though, but I'll try them. Mainly to prove that 108 figure more.
The lobe has .338 to .339 lift. Multiplied by 1.5 gives me .507 and .5085, respectively.
