302 balancer
 

This balancer is hanging off the crank of my '69 DZ 302 - what the heck is it from cuz it doesn't look like any Z28 balancer I'ver ever seen https://www.yenko.net/ubbthreads/pics...2-balancer.jpg

I do not know but not all 302s got the 8&quot;Big Thick Balancer. I think a light weight balancer and light weight fly wheel would rev faster.

Re: 302 balancer
 

on the farm we had a 68 chevy C50 grain truck that had a balancer like that.

The 69's were one year style with the offset timing mark and the extended &quot;Y&quot; shape on the front of the balancer. Don't think service replacement balancers had the assembly line &quot;Y&quot; shape on the front.

So some 67 but all 68 were like the the L-79 harmonic balancer. Were the so called ce 302 were in early 68 the L-79 or the big 8&quot; harmonic balancer. Any help.

Re: 302 balancer
 

1966 and 1967 L79 balancer's were like the 67-68 Z/28 balancer's. They look just like the 69 302 balancers but the 69's have the offset timing mark. The 1969 balancer also used a redesigned timing chain cover because of the offset timing mark. The width of a 69 302 assembly line balancer is about 1.75 inches just like the 67 and 68 balancers.

Re: 302 balancer
 

The 66,67,68,and 69's 302 balancer all look the same and are 8&quot; balancer. So the truck 350 and car 350 are all the same too. So the different cu. in. and the different crankshaft all took the same 8&quot; Harmonic Balancer{except the 400 sbc}.

Re: 302 balancer
 

350/300 or 350/250 motors are different Paul. They are 8&quot; but much thinner than the L79's, 67-68 302's and the 69 302's. My 69 SS nova is not the same as my 69 Z/28. 8&quot; but thinner.

Re: 302 balancer
 

The balancer pictured in the first post is a 69 DZ 302 or not. Also only thick 8&quot; 302,327,and 350 balancers is for a large or small journal and 1968 302. Is a 67 a small journal crank and a 69 has a large journal crank, I would think the balancers would match the crank.

Re: 302 balancer
 

first picture looks like a 283 or 327 balancer. 67 Z's were small journal cranks. Pretty much a 283 crank was used for the 67 Z/28's. 68's and 69's were large journal cranks but all Z/28's 67 thru 69 took the wide 8&quot; balancer. 1969 was the first year for the offset timing mark though.

So...who's on first?

Re: 302 balancer
 

So you can use a small balancer...

Re: 302 balancer
 

Gotta bolt the fan belt pulley to something.

Re: 302 balancer
 

Previous owner of the engine changed to the smaller balancer for &quot;more revs&quot; apparently. [img]<<GRAEMLIN_URL>>/dunno.gif[/img]

Re: 302 balancer
 

don't think so! maybe it is a 283 crank with bearing spacers? That is the correct &quot;V&quot; at the crank butt.
