cam timing?

[TurboShadowES]

if my cam timming is off a tooth would it cause me to detonate alot? around 10 psi? after reading a book i have on turbo's it says that cams can change the compersion ratio on a turbo'd engine.. so if my cam timing was advanced a tooth (or retarted not shure..) would it cause me to have higher compersion and lotsa detonation... i have a nice IC and running 91 octane... still detonating at 10 psi!

yes this can cause detonation.i tried advancing the cam timing one tooth on my 88 daytona and ran into the same problem.

hmm... guess ill have to retime it this weekend... is there a easier way to check?

line the crank on zero through the bell housing.pull the upper timing cover and check the marks...the 2 arrows shoul be pointing where the cam cap seperates.as for the intermediate shaft i ussualy take off the distributor cap then pull the dist out and look into the hole and see if the 2 notches are parrelel to the crank ie straight across left to right.hope this helps
