Hello all gearheads........

I got a 383 that I bought from a friend in Oct 2007. 1 flip of the key and it started perfectly in his car. I pulled it from his car and sat it on a stand until April this year. I pulled the starter off to paint the block. I put the starter back on with the 1 shim that was on it before, now it grinds against the flywheel. When it doesn't grind, it dissengages right before the engine cranks. What could this be?

Most likely lack of voltage, or not a good enough ground. Also is the flywheel/flex-plate off of the engine, or out of your vehicle it is going into? There are also 2 different flywheel ring gears, 1 with 153 teeth, and the other with 168 teeth.(this one is most common)

The flexplate is off the motor. The only thing I changed on the motor is the color and the valve covers, it had Chevrolet covers, I got some fabricated covers from skip white, I got the motor in an 84' Cutlass. I read another thread and considered adding additional grounds in my car. What I have now for ground is 1 from the battery to the fender.......battery to the block........and block to firewall. Any suggestions on where they should be added? Again this is an 84 Cutlass.

I would check to be sure you are using the correct bolts. Make sure there is no paint on the surface where the starter bolts up. From what you said you did there is no reason anything should have changed. Chevy starter bolts are knurled so they fit tight in the starter housing. If you use regular bolts the starter can be tightened in the wrong position.

I sanded paint from where ever I put a ground wire and I was careful not to paint where the starter attacthes to the block. The starter bolts are not correct SBC bolts, but they are the bolts that held the starter up before I took it off. Im going to buy the bolts that have the knurled section on them to see if that makes a difference.

Also, does any body know how to downsize a picture so that I can post one on here? This is my first engine install, I got it all done up and I gotta show it off!!!!
