Hi guys,

Not sure if I'm not sure if I'm on the correct thread or not but I'll give this a shot. I have a 1967 4 sp. toploader from a Mustang that I want to mate with a 1979 302 from a F100 that was auto. I know the flex plate needs to go and I need a fly wheel. Can someone tell me strait forward what I need to do? What size in inches and weight fly wheel do I need? Do I match the dampener to that?

Thanks in advance if anyone can help.

 

Ok... Where to start, the truck I bought has paperwork showing that it has a motor from a 1979 Lincoln, it now also has a 3 spd top load tranny c4 I think. My problem is this I am getting a terrible grinding sound when I try to start it... I have replaced the starter,silanoid,and battery . The truck will start 3 or 4 times perfect then the grinding is back, then I shimmed it..4 or 5 starts then grinding... Help me please...

 

You've probably got a starter for an automatic transmission. Replace it with one for a standard transmission (or switch the starter snout).

The drive gear protrudes further on the automatic version.

 

What flywheel you need depends also on what bell housing you're using. You need a 28 oz/in flywheel. If that Toploader still has the original bellhousing it came with bolted to it, then it'll be a 157 tooth. It should have an aluminum bellhousing if so. If it's cast iron, then chances are it uses a 164 tooth flywheel.

 

C4's are not Toploaders, Toploaders were manual transmissions. C4's were automatics. Be that as it may, if you left the block plate out between the engine and bellhousing, that may also be why it's grinding. If the plate is there, it should never need shimming. Or the starter ring gear teeth are missing in one or more areas of the ring gear, in addition to what beanscoot suggested.

 

Ok, here's my dilemma. I have a 1978, 302 that was a factory fresh rebuilt but it didn't come with a flywheel..... so I am assuming that the motor uses the 28oz flywheel, dampener imbalance and crankshaft but is there any way to check? I would appreciate any help.

 

You should be able to ck the crankshaft casting numbers . If nothing else , call the builder and find out what crank they used .I ran into this in my 78 . After I put it in I had one heck of a vibe . Turns out , it has a crank out of an 84 302 ! I switched the balancer and flexplate and all is well .

 

ok, I looked at the crank and it has a 2M stamped on it... just took a little sandpaper to find it.... all of you help has been appreciated!

 

Oreiley lists that as fitting a 78 302 . 2MAE for 84 302 . But ck further to be sure . Good luck !

 

JWC, if you read my first post, I stated it was a 1978 302 and all I was looking to do was verify the crank installed was a 28oz crank which is what the 2M did.

 

I was just saying I was not sure about the numbers . Glad you got it solved .

 

I've got an '83 f-150 with a straight 6 300 in it. I'm trying to figure out if a flywheel from a '85 351 Windsor will match up to it or not? I'm wanting to switch out the motors as the straight 6 I've got has been more of a hassle to rebuild (as I didn't have all the information on the engine like I thought I did) and I can trade it for the Windsor. Any ideas?

 

You need to keep the flywheels with the corresponding engines. If you swap a 351w into your truck, you need to keep the 351 flywheel with that engine, you can't use the 300-6 flywheel with the 351 and vice-versa. Are you asking if the 351 flywheel will match up to your current clutch/bellhousing? If so, that depends on the diameter of the flywheel. Count the teeth on both flywheels and see if they're the same.

 

The 300 flywheel is a "neutral" balance part. The 351W used a 28 oz/in flywheel.

 

"I've got an '83 f-150 with a straight 6 300 in it. I'm trying to figure out if a flywheel from a '85 351 Windsor will match up to it or not?"

Well, as has been said, they are differently balanced so should not be interchanged or destructive shaking and vibration will occur.

However, in one way the answer to your question is yes, the 300-6 flywheel will bolt up to a small block engine.

The 300-6 flywheel can be a useful piece when putting together an engine such as a stroker that has been engineered to use a "zero balance" flywheel.
