O.K.,

I ran my own comression test on my 1977 280Z L28 with a N42 Block

and N47 head with clogged #6 FI Port.

Engine was at operating temperature and my compression came

up as this.

Is this good or bad?

Clyinder/ PSI

1- 150psi

2- 150

3- 150

4- 189

5- 152

6- 150

With teaspoon of oil.

Clyinder/ PSI

1- 190psi

2- 180

4- 170

5- 180

6- 180

How did your engine turn out?

thxZ

Wing, I question the numbers on the dry test of #4 and the wet test of #1 . Did you do the testing only one time through all cylinders dry and the same wet? Those two high numbers don't figure right when looking at both testing.

The numbers for the dry test of #4 went down with oil added? I think the rest of the numbers look great on both tests . I think you got faulty readings though concerning #1 & #4 I say test it again dry and see what it shows.

I think what TamoHawk was referring to is my engine is done now and ready

to drop in.

And for you Bean I refer you to this thread right here for those

odd numbers your seeing
