I just put a new (used) 350 engine in a 1978 1/2 ton Chevy. What's the difference in starters from a large flywheel to a smaller flywheel? What kind of starter do I need to get for the smaller flywhee

I don't think the number of teeth on the starter matter. You just need the right starter for that engine.

In 1968, the 283 CI was replaced with a 307 CI. In 1969, the 327 CI engine was enlarged to the 350 CI. Those are the options for those years, small block v-8s: 283, 307, 327, 350; Big block v-8s were the 396 CI, and 402 CI. An old chevy guy might be able to tell you what engine you have, by looking at it.

most starters are the same on chevy 350s should bolt right up, if you have to change torque converter, but most chevy 350 flywheels are universal. that's the good thing about a chevy most everything 350 smallblock bolts right up. hope this helps

There are two different size flywheels (starter ring gears) on these engines. It sounds like you have the flywheel with the higher number of teeth. Find a good auto parts store to get the right starter for your truck.

You need to replace the starter solenoid.

Yes, the engine will swap fine, for the vacuum lines Go to Autozone.com, become member, will give you repair manual,location of parts,diagrams.

OK,here we go. Remove starter, exhaust pipes if in way, flywheel pan. Your have raise engine 3 in. Unbolt pan.

There are two different size flywheels used on Chevy engines.The straight across bolt pattern is for the small diameter flywheel the staggered pattern for the large flywheel.The block is drilled for both starter patterns.The F- bodies in 1986 came with a small flywheel-so you should need a starter with the straight across pattern.The depth doesn't change ,just the distance away from the crank.

If when you jump the starter with a screwdriver & it spins without engaging the flywheel - I would say with reasonable confidence that the starter is bad..

Hope this helps !!
Please rate me good ;o)

hi there this seems that you have some bad teeth on the flywheel the flywheel attaches to your motor and transmission the starter motor rotates and spinns over the motor to start if the teeth are gone in certain areas on the flywheel then the motor wont spin you need to remove the transmission and replace the flywheel ,once replaced then make shure the teeth on the starter motor are new not cammed over as you mentioned was the isue earlier hop this helps let me know ho this works with a vote of fixya thanks for using sutch a helpful website like fixya
