SBC 283 c. i. ?

I am wondering if this is all I need for my balancer on my 283? It has a timing mark on it and the crank is not drilled and tapped for a center bolt. I am just wondering because a friend brought over a balancer off of another 283 and it looked more like a balancer should but it was to big for this engine because it would hit the timing tab on the timing cover.

 

the stock 283 balancer is small , but it looks like you are missing something. here's the one for mine . it's 6" OD

can you post a close up picture?

 

Ok I just went out in the garage and took these pics.

 

that doesn't look right to me

 

a dirt track friend of mine would get balancers like that off big trucks. just a bunch of pulleys & once they were removed it didnt even look like a balancer behind them but it is & thats what he ran.

everyone always asked WTF is that? he'd just smile.

 

The early 283's didn't have balancers.

 

You my have some sort of marine coupler , havn't seen one quite like that but some boat drive setups were run off the front of the engine .
The 6" that 36-3 window shows is what it probably should have
PS> you might want to drill and tap that crank I've seen a few balancers walk off those early non drilled one .

 

i'm with you 3 window,that just don't look right at all,and voodoo,never seen a 283 with out some type of balancer..richie............

 

I've got a '62 283 lying in my garage with the same hub on it as in the picture.

 

i've never seen anything like it , both the 283 in my `36 and the one on my engine stand ready to go in my new project have balancers like the one i posted...i guess you learn something new every day on here

so what years and what applications was the one lockwoodkustoms posted used?

 

I agree on the drill and tap comment. A friend launched his balancer in a 65 impalla 327 with that pressed on style. Ripped a hole in the frame and tore a bunch of stuff up.....not to mention it could become lethal.
Your balancer doesn't even look like it has a rubber membrane in the middle.
The aftermarket performance balancers have become realy reasonable...I would think they could help you out.(try starting with summitracing.com).
Remember you are talking about safety of you and the motor.

 

It doesn't have anything on it(Rubber). But,This set up did come from some guys who were into dirt track racing. I can put another balancer on it and just change the timing cover right?

 

if you change to a different balancer,. keep in mind the chevy moved the timing marks on them through the years. i always bring #1 up to TDC and check the timing marks while assembling the motor so i know they are correct

 

I've got a 66 283 (from Canada) that has a hub only. It never had a balancer. I had the crank drilled and tapped for an aftermarket balancer.

 

I just shot these pics for you its fine what you have right on !!

 

.....a bit off topic, but you have two different heads. Are they "matched"?

 

A lot of those early 283s only had the hub as shown in your picture. Don't know why, but many never had the elastomeric damper.

 

because they were balanced at the factory...

 

The early motors had dampers that were one piece with the pulley, sort of a rubber or rivet holding them together, could be that was one that had the pulley removed.

 

Ive heard chev didnt drill the cranks till 64 or 65

 

I have a couple of 283's. One has a normal looking but small balancer, and the other just has that hub. I had brought it up with my old engine builderfriend and his reply was that the early ones just had that pressed on hub.

 

Not sure that is the answer, as balacing has nothing to do with running a damper.

The hub does look just like the two piece rivited early balancers, but I can assure you that some 283s did come with just the hub - no rubber or inertia ring rivited to it, just as you have on your engine.

I don't think they started drilling cranks for bolts until 68-69 time period. Maybe sooner on HD or high perf applications?

 

they may have called it a hub,but its a balancer off sorts,and yes it should be drilled and tapped.....richie............

 

What about the late model cadillac engines that are nor held on with a bolt . They are pressed on as well. But I am no engine guy.

 

Looks like the hub only, no rubber ring and no outside ring. The outside ring would have a timing mark in it and the whole thing would be closer to the timing tab than what you have pictured. The 283's didn't have a hole threaded in the end of the crank. This practice started on the 327's in the late 60's. I think it didn't start until the "new" large journal cranks were produced. You can drill and tap the crank if you want. Chevy also started making larger balancers in the late 60's early 70's. They might fit the crank, but the timing mark may not be in the same location as the smaller dampers. Also, the timing tab will be in the way of the larger damper. You can buy these things new from Jeg's and Summit.

 

57Heap, There is a timinig mark on the one I have.

 

My 327/300 hp has a Bolt in the Center & its a 1963
I have seen the early 283's and some looked like the OP's

 

Had a '65 Chev with the original 283 and it had the same setup; very strange looking compared to 327's and 350's

 

I think Dooley is rite looks lke a modified early crank hub. Chevy had to start dilling and tapping cranks when they started hanging power steering, etc, pully's off the end of the cranks....................

 

Thanks for all the help guys I appreciate it. I guess it is what it is and I will make sure that the truck is safe. I will not be running anything off of the crank pulley a local engine guy assured me that it should be ok with what I have. I will be posting more after this weekend hopefully of it running in the truck.
