I ran a static compression test yesterday and it arose some questions....
#1cyl. 170lbs.
#2cyl. 165lbs.
#3cyl. 160lbs.
#4cyl. 175lbs.
#5cyl. 165lbs.
#6cyl. 175lbs.
do these numbers look ok for a stock 72' L24 with the E88 cylinder head??? please let me know I thought that the numbers were too high.... but let me know -k-...

That sounds about right, but maybe somebody else would know better than me.

I just bought the car and when I saw the 170lbs on the #1 cyl. I nearly freaked out. I thought the 170lbs was too much for a 8.8:1 compression engine....but the chilton said that under tune up specifications that it should be within 171-185 for a stock motor, does this seem odd to anyone but me? I thought that 170lbs should be around 10.5:1 compression. Someone correct me if I'm wrong please....
And does anyone have a driverside gas tank strap for a 72' 240Z????

I think 10:1 would be little bit over 200lb/in. It'll depends on the cam you got too. I think mine was only about 150-160 with 274 cam. I really need flat top pistons...
