Hi, in my s2 88 Erst I had what I was told to be a Kent cvh 31 cam, I rebuilt the engine car a few years ago and in been in dry storage since, when then engine was built I never set the cam up only roughly to get it to run in, now when the boost was turned up to around 12-14 psi (and yes the car is chipped) then it would back fire. Fast forward to now I have set the cam up to 112deg atdc on full lift as per settings. When I tried the car again it now misfires under load/boost so I decided to check basics and rule out simple things plugs leads fueling, ect...so Then I decided to re checked the cam and found this stamped on the end kcvh 35 now if this is a Kent cam ? Then the setup is not 112deg after tdc it is 118 atdc , now my question is A is this a Kent cam sports r 35, and B if it is will this 6 deg of crank rotation cause me a horrendous misfire on boost. ? Tia.
