Hi guys. I'm new to the forum and am desperate for an answer. So here's the run down. It's a 1982 mercury capri with around 400 horsepower. I took it apart in December because the intake gasket and head gasket and header gaskets were leaking. While the heads were off I polished them up and made them glass again ( they were previously ported) both heads were shined up and put back on. I bought new lifters which were the same ones that were in it. I reused the push rods because they were straight as an arrow. Now here's the change up. I put full roller rockers on instead of the roller tips that were on it. Everything was too zero lash and snug and done right. I didn't do it I had my mechanic do it. Dropped the intake on and heres another change I did. I removed the old duraspark and accel box that was in there and replaced it with an hei with the coil built in. I also removed the mechanical fan and put an electric fan but that's shouldn't matter. When I first went to fire it we put some gas down the carb and it popped on a few cylinders and that was it. We had no spark and we blew the fuse. So we decided to wire the distributor straight the battery. We have spark but weak spark. When I first turned the key something smoked in the cab ( possibly ground). So I'm looking for answers. Could my hei be junk? I'm getting fuel. I have spark ( not much but spark is spark) and I have plenty of compression. In theory it should run. I know that I am 180 on at tdc and have tried numerous timing combinations. (First time timing a ford, Chevy all my life haha) any insight on what might be wrong? It ran the day I parked it in the garage. I'm almost certain it the ignition, I just need to know where I went wrong. Any questions ask away!!
