lifters?

[NateD4]

Hey NateD4, I posted a while ago under general discussion but since you got the 3900, you should see if the LSX lifters will fit your block. I know that the 3900 has DOD just like the LSX engines do, so what are the chances that GM would spend all that money to design 2 different DOD lifters for 2 different engines. I was thinking the same thing bout the vvt 3500 since it has a smaller stroke, those lifters and 8000 rpm's isn't far away.

When GM is making a few hundred thousand of something if they can make the lifter shorter or move a hole to save cost they will even if that means several thousand dollars (or more) in engineering.

Anyone have a set of LSX lifters I could try?

I bought a set of LS7 lifters, and there's nothing special about the insides of them compared to a set of 60* lifters aside from the springs, nothing appearing to be ceramic at least.

well, they're done!

The LSX springs are beyond a shadow of a doubt have a higher rate than the 60* springs, My only concern is that the bind height is also taller, I haven't measured it, but it is taller (more coils)
