Jeep Strokers

I have a 96 4.0L

Just wondering a few things:
What the compression ratio is?
What material the valves are made of?
Crank cast or forged?

Thanks

Comp is 8.8:1 SCR, intake valves are steel, exhaust valves are stainless steel, and the crank is cast.

Thanks Gradon,

By chance do you know if the pistons are cast or forged?

i *believe* pre 96 are cast. post 96 are hypers.
