does anyone know the open close specs on lg4 cam


Im trying to check cam timing and I need the degree specs for valve opening and closing I have lift and duration need the degreees they open at






any help wud b great

 

Given that the LG4 cam was ground on a LSA of about 109* (which sounds tight except that it's a microscopically-small cam so it still has almost no overlap) all you really need to know is the ICL and you can calculate the rest.

Problem: I have no idea the factory spec ICL of the cam. I suspect it's probably between 107-109*, but that's just a guess.

You could FIND it by checking/degreeing where the intake lobe hits max lift using a known-accurate chain set installed at 0* adv/ret (the definition of ICL) and then do the math.

 

Yeah on that cam, you could hide the lobes with Clearasil... you need a micrometer to even find them.

What difference does its event timing make? It's GARBAGE. Throw it in the trash and get something less appropriate to a tractor. If you're actually running it, just put it in and be done with it; ya got whatcha got.
