trying to tune a new 455 build in my '67 GTO. Starter is not engaging the flex plate.. Its a new mini starter from Summit. I installed it per the instructions, checking the pinion to flex plate distance and the pinion to flex plate teeth engagement. Used two shims get it where I thought it should be. Tested it with the coil wire ( so the engine wouldn't fire), it spun the engine and sounded fine so I considered the install good. Fast forward to the engine tuning session a few days later. On the initial turn of the key to the run position it started right up but I had to shut it down a few minutes later due to trans fluid leak. After fixing the leak I tried to start it again but this time no crank, only the sound of the of the starter pinion firing. I got under the car to check it out while my buddy turned the key and I could see the pinion fire out and but not enough to engage the flex plate and crank the engine. I may pull the starter and bench test it but other than that I don't have a plan. Sorry for the long rant and let me know what you think. regards.
