Author Topic:   new engine start up
posted May 31, 2004 10:26 PM
I've just built a 383 with JE 13:1 forged pistons and 6.0 rods. I carefully checked all my clearances , but I'm having a tough time getting it to turn over. I am using a stock starter and it just engages against the flywheel and hums. It's brand new and I checked it out before I installed it. I can turn the engine over with a wrench on the flywheel so I know its not locked up. I'v even removed the spark plugs but that doesn't help. What would be a good starter to use to turn this thing over. I'm getting frustrated. Is the problem caused by my high compression? Thanks for any help and suggestions. I'm new to this.

Check your grounds and make sure they are tight and clean.

sounds like that starter is weak.
Our motor is making compression like yours and we broke the nose cone on a stock starter we had to switch to a gear reduction type. We got ours from speedway motors for 100 bucks.

We are running 400 about the same compression always had starter problems bought a speedway starter it was junk took about 3/8ths in half shims still would not work right bought a tilton super starter worked perfect after spending all kinds of money buying cheap stuff sometimes its better to buy the good parts first

a new engine like that deserves a new, reduction, quality starter.
also check your main power cable size from the battery to the starter. most cables are severly undersized for the power required by a quality starter.

Thanks for all the replies. I wasn't sure what was a good starter to use. Do I need one thats 2hp or 3hp? My cable from by battery is 2gage.

May sound silly, but it happend to us once, check to see that your harmonic balancer isnt hitting the water pump. We had a goofy water pump that hit on the harmonic once and it did exactly what you are seeing,went to turn the motor over and it didnt do anything, started just hummed and nothin happened. we just ground the water pump a little bit and we were good to go.
