Thread: sbc 327

New to this site, and it looks real good ! I have read through the posts and gotten some good ideas, and have a few questions related to my '69 sbc 327. The balancer is a 6 inch and the timing cover is aftermarket with a tab that is for an 8 inch balancer. The original tab was welded on to the cover, so setting the timming is hit or miss. I found a tab for a 6 3/4 to 7 inch balancer, but TDC is way off, and the spacing between degree marks are not the same as the 8 inch balancer. What have you gearheads been doing with this, to be more accurate ? Can I put an 8 inch GM balancer on this crankshaft, which is NOT threaded for a retaining bolt and expect it to stay on ? And just for my learning experience...when people talk about 2 degree advance or 10 degree advance on balancers, does this mean the marks on the balancer are that much from the center of the keyway or just what is meant by this?

..The "0" shows the number one piston at TDC..(top dead center)..The marks show the degrees of the number one piston at BTDC..(before top dead center).. or on some emission engines ATDC.(after top dead center)...It all relates to the camshaft and distributer timing...........There have been so many balancers (dampners)..made for each application it can be a nightmare.........A vacuum gauge works good to aid in setting the running timing...Always use manifold vacuum...In other words connect it below the throttle plates.....................................I know.....Lets ask Streets...He's got info up the ying ying...........Hey .!! Streets.....you reading this.???......What is the best way to get the correct dampner anyway.?????.....

Ignore me, I'm a troll
