Non-turbo 617 Camshaft vs. Turbo 617 Cam
 

The cam on my 300D is slightly worn, nothing really major just a little worn.

There's a 1983 300SD in my JY with a like new camshaft.

So heres the question, is the valve timing on the turbo diesels the same as the non-turbo's? Is it so different that I would see a decline in HP, or might I see a gain in HP? Has anyone done this before?

Yes I know I will need to use the rocker arms from the turbo diesel if I use the camshaft.

Thanks

As I recall, the lift and duration are different.

Very different. Youll have less power and mpg with the turbo cam because there is no valve overlap to scavenge the cylinders.

I thought there might be a difference, but I was hoping it would improve performance, haha.

Thanks for the input.

How much ' valve overlap' is there on the NA cam ?

I may have an NA cam from a 617 i can get a hold of.

my daughter is heading for lakeland soon, and I have 3 useless NA cams if you want one.

How much for 1 useless NA cam? Thanks

Thanks again everyone for your input, im going to use a NA cam.

Be sure to check on the material used for the cams and the followers.. they need to match... it is somewhere in the FSM...

I also need some more rocker arms, my originals are pretty bad.

would you want the whole head?
