Tearing Engine Down Questions

[Guest Anonymous]

Started taking my engine down this week. Doing this slowly and checking things as I go.

 

3 questions

 

I pulled the heads and found TDC. I was suprised to find that the pointer is off on the balancer by 10 degrees. I have been runing the timing locked at 36 deg on to learn that it has been running at 26 deg?

 

1.I wonder what effect this had on performance?

 

Trying to determine deck height. I have been trying to use my dial calibers an come up with around .10. But it is had to tell since the block is O ringed.

 

2. What is the best way to do this?

 

My oil pan and pickup apear to have been in contact. 7 qt Miloden Pan with trap doors windige try etc.

 

3. What should be the clearence?

(1) 26deg versus 36 degs total timing, you will be atlease 50 hp/ft lbs lower on hp/tq than you could be if your timeing were correct.

 

(2)look here

part numbers #4900,#4909

 

if you dont have the correct tools lay a strait edge like a metal ruler accross the bore on its edge so it wont bend and measure the distance from the top edge of the ruler to the top of the flat edge of the piston at TDC, subtract the thicknes of the ruler and you should have your distance down the bore

 

(3) oil pan floor to pickup clearance should be 3/8"minimum to 1/2" maximum
