Help with 4.6 stroker rebuild after failed cam gear

[dwg86]

Did you degree your cam?

Cam was put in straight up dot to dot. im using ngk bkr6e. distributor is in there but i had to cut the ears off cause it was about 1/8" off. 24* mustang injectors. i have an afe but the o2 sensor is bad and i need to get a new one. Stock map right now. pings under slight load. under 80% throttle for sure. stock map.

If you didn't degree the cam in it could be off... especially with the double roller sets.

[kkchevy3]

using a single roller setup

the motor seems to ping in like 3rd or 4th light throttle up a hill. I guess there's really not much i can do at this point externally right?

The pinging sounds like a fueling problem. What injectors? Tune?

[SilverXJ]

x2 on the injectors and fueling mods. What gas are you running? With your 9.6:1 CR you shouldn't be pinging with the 68-232-4 cam.

[kkchevy3]

using the mustang 24 lb, and i was running the 68-232-4 cam. now running the lunati voodo. I guess ill buy the new o2 sensor for the wideband and figgure out what the mix is

Did you ever get a resolution on this?
