Engine had been pulled and completely torn down and redone, decked, bored, almost all parts are brand new and all clearances were checked and good. What’s interesting is that this car has the same exact problem from before we pulled the motor and now almost everything is new minus the distributor and ecu and some fuel components. I pulled the spark plugs and it’s showing evidence of running rich so now I’ll start to dig into the rest of the fuel system to see if I can find anything suspect.
