madkaw Posted September 11, 2006 Share Posted September 11, 2006 Finally got my head back from the shop(another story), but I put the degree wheel on her this week and would like some feedback guys. What I have is a e-88 head that has been completely redone with 280 s.s.valves and I installed a stge 2 schneider cam kit ,274-f grind going on a .40 over 2.4. The cam card calls for 2 degree intake opens btdc -2degree ex. closes atdc 32 degree intake closes abdc 36 degree ex. opens bbdc My numbers cam up 1 degree intake opens ADTC 3degrees ex.closes btdc 34 degrees intake closes abdc 35 degrees ex. opens bbdc First off, what is up with the negative degree number on the exhaust side. I am interpreting this as 2 degree btdc-am I correct? I used the #1 hole on the sprocket since the other holes took the numbers further away from specs. And yes I did find tdc the right way with a little help from BRAAP sticky. Doing the math I concluded that my intake center was right on-do you agree?

madkaw Posted September 11, 2006 Author Share Posted September 11, 2006 Well I have been reading as much as i can on this and I think i did do something wrong. Since my dial indicator doesn't have a long stem I believe I had the indicator at a slight angle on the valve which would have changed the numbers slightly. Some of you valve geometry GURU's might be able to tell me how that effected my numbers, I didn't do very well in geometry during school but I am thinking that this would cause my numbers to come in late which would make my numbers look better. Anyone???? Quote Link to comment Share on other sites More sharing options...
