HellooooFABO!
I have a friend who has a 67 fastback and experienced a 'tick'. it seemingly was coming from the back of the motor/trans area (auto). He has pulled the trans and wants to start the engine to narrow it down to it being the trans.. or engine. He wants me to build a bracket to hold the starter and then plans on putting a flywheel on it that he borrowed. Im not sure he has the proper flywheel, I think it may be a truck one but I havent been doing mopar stuff long enough to know. I have a /6 flywheel. His converter is 122 tooth. I have a small block bell but he for some reason didnt want to mount it for this. Im kinda following on this one, but Id like to know if the /6 flywheel will work. Im in the market to get a flywheel for a 360 I have lying around, but with shipping and tracking one down used the timeline is not lining up. Just spit ballin....any ideas? Im probably missing something easy here.

Thanks!
Clem

We think its the converter....but just a guess.
 
Count the teeth on the slant. I have no idea offhand if that will work. What, you are going to use your bell for a bracket pattern?
 
Check the flex-plate closely for cracks. Drop it on the cement floor; if it sounds funny, check it again.

At idle, for testing purposes, you can put anything on the crank that puts the ring-gear in the right spot; but a bellhouse bolted on would sure be handy. When the starter whacks the ring-gear it takes a lot of torque to get her moving, applied in a very short period of time. if you build something (a waste of time IMO if you already have a BH sitting there), it better be strooong.
 
He needs a slant 6 bellhousing. That's the best way. PLENTY of cheap ones around.

Slant bellhousing? He's got a 273...

If it's 143 tooth, 11 in. clutch- it's a truck flywheel.
Passcar flywheels came in several sizes, most commonly the 130 tooth, 10 1/2 in. clutch size.

No go- crank pattern's different.

He wants you to do a couple of days of fabricating to avoid doing a 10 minute bellhousing install? Run away. Quickly.

The balance is different between the 273 and a 360 anyways.

As far as the "tick", it is a 273- are you sure it isn't just in need of lifter adjustment? Solids in a 273.

Oh ok. I had slant 6 on the brain. My bad.

This is what I use to start and run all my motors, I cut an old torque converter in half. Works great.

Yes, I believe this would be the best pattern. I am not sure why he doesnt just bolt it up....tough to get to bolts?

Sure it's not an exhaust leak?

It might be, but when I heard it I ran my hands around the manifolds and didnt feel any puffs....I wish I had taken a video. I will during the next startup though.

Ill report back. Ill try to have more pictures. Its really only half a story without pictures. I should know better.
 
I'd adjust the valves first and then really look for exhaust leaks. I had to have my Commando Y pipe welded to stop the invisible exhaust leak. You could not tell till we cleaned it up.

Agree with all the above. It's like WTF IS GOING ON HERE?
 
Get out your automotive stethoscope and figure out where the noise is coming from. THere's a good chance it's the valves needing adjustment. A damn good chance.
 
while you have the trans out check to see if the torque converter bolts were rubbing the block
 
so a stock 273 flywheel is 130 tooth and what is diameter across ring teeth to ring teeth? or if 130 tooth and has correct bolt pattern is confirmed car flywheel?

No a 64-68 9 1/2" flywheel is 122 tooth but that's a manual transmission flywheel. That's what came stock on 273's of that era.
 
Mopar automatics don't have a flywheel. The starter ring gear is on the convertor and that is connected to the flywheel with a flex plate. You knew that.

Yup, that's where to start first. It's pretty rare for a transmission to make a "tick". Flex plates, attaching bolts, bent dust cover, exhaust leaks, valve clearance, yes.

ya, I was checking about since he wants to do this start up without the converter, putting a stock flywheel on. He doesnt know what he has (he borrowed a flywheel from a buddy) so im trying to identify what he has.....it fits the bolt pattern and has 130 tooth....Ill try to get a pic...I dont know what im thinking trying to navigate this without pics! its crazy right??? I find myself sighing when I see some threads without pics or vids....now Im that guy....gah!

I agree and wish I had when the thing was 'startable' so now its a case of getting it started again without the trans on it since we have the opportunity to do it without the converter seems like a good case to eliminate or separate the possibilities. Again, Im not running the show, Im just a clown in the corner as of now. Honk Honk!
 
finally some pics...

This is the bracket he bought. It didn't fit but it gives you the idea of what i will make once i identify the flywheel he has. The second pic is the template he made to use to make the bracket. Dunno what the first bracket fits but shares 3/5 holes. The third pic shows the other holes lining up. The last pic is of dudes template on what i believe to be a small block bell.

Yup, the flywheel needs to match the bell housing or the starter will not engage the ring gear.
