So I have a 350 that I installed a bunch of new parts in. I installed a new oil pump when it was on the stand. I forgot to install the steel oil pump shaft before I installed the intake. I put the tranny on and put it in the car as was running out of time. Few days later I pulled the pan in the car and removed the oil pump and put the shaft in and reinstalled it. I dropped the distributor in and ran the motor and broke the new cam in. Each time I shut it off and try to restart it just cranks and has no spark. This is a brand new distributor. Motor was set to tdc and on zero when timed. I pulled the distributor and turned the shaft with a screwdriver. The shaft feels like it has some resistance and feels like it wants to unwind when you turn it like it backs off some. Before I put the pump in it spun freely and this is all new parts. Feels like engine is out of time. Installed new double roller timing chain,gears and camshaft, new lifters, new springs and new retainers. Not sure if something is binding or if it is supposed to feel this way being new. Any help would be appreciated.

you spun the oil pump shaft or the dist shaft and it feels to have some resistance? Oil pump if primed and working will definitely have some torque on it. Dist shaft should spin free. Check under the rotor in case you lost some springs or something is dragging... As asked do you have oil pressure? Pull 1/8 in plug or pressure sensor by the dist. on back of block and crank and you should get a good shot of oil out of that. Do you have power to the dist. when you try and restart if no spark? Are all new parts installed correctly and rockers are set properly?? Just trying to name off some simple stuff not saying it was put together wrong.... when it runs does it sound ok or out of time? Must of ran for 30 min or so if you broke cam in.
When you turn the oil pump shaft with a screwdriver with the distributor removed you turn it so far and let go and it backs up some. All the other sbcs I have turned it stays put. Just feels like it wants to unwind when you let go. Its hard to explain. I havent messed with it lately but will check for oil pressure. The car was built last year but didnt get to run it so it sat over the winter and I was having these issues with it last fall. Yes, I have power to the distributor and have short temp wires ran straight to battery to test. To my knowledge everything was put together correctly. Yes, it ran for around 30 mins. The center exhaust ports were glowing on the headers near the head. It seems to not want to start and has something wrong with the distributor. Im assuming I have more then one problem like bad module and maybe timing off. I will check oil pressure and retime and go from there. The distributor is a Jegs brand. Owned another and worked great.
