1982sc cam timing values in waynes book
 

Why does the 1982 sc have two different cam timing values depending on the engine #?

1978-1983sc 930/04-/10 is 0.9-1.1

1978-1983sc 930/03-/17 is 1.4-1.7

If one of these values were set incorrectly (in other words reversed) how much would that effect performance?

Thanks

Hi there..the bottom number 930/60.... are for Turbo..it could be a misprint in that Wayne book -i have never seen it ...For your engine you should go by 930/16 so the 1,4-1,7

Take a look in the middle of the page those are the numbers I'm talking about Engine number 930/04 and 930/03 turbo is 930/60

i did have a look and you said or actually have written this ..1978-1983sc 930/60-/66 is 1.4-1.7..right those are numbers for 911sc 1982-3 compare to earlier model of 911sc..

no problem..but you did do the cam timing as for the 1,4-1,7 on your 911 ..right?

Ivan

Yes 1.4-1.7
