ProForm 141-728 Harmonic Balancer Cover, Timing Marks, Bowtie Logo, Aluminum, Black, 8 in Balancers, Compatible with Small Block Chevy, Each

Simple with excellent fit over a standard 8" balancer. Quality seems solid, not really tinny yet thin enough to not add a lot of mass as it rotates. Functionality can't be more straightforward, markings are clear and painted white over the black body so easy to read and looks clean. Good value and easy way to clean up that rebuild.

I installed it on a zz4 sbc 350 in my 88 chevy truck you have to pull the center harmonic balancer bolt as well as the 3 pulley bolts. tdc mark on cover lined up perfect with the original balancer mark. It also has 90 degree marks to adjust my roller rockers using the 90 degree method. No unwanted contact with timing cover or water pump not even close. very nice piece. pointer does not cover the timing degree marks as some say. Get the black one marks are easy to see.

I purchased this by mistake. Wrote seller and they had my refund In 10 mins. Dont get any better than that. They are true blu Trump fans too so you know they are winners. I always buy from them.

Fit good easy-to-use

Looks like a good cover, but didn't use it

Rubbed on timing mark and screwed it up. Removed and threw away.

The outside diameter of the cover and my harmonic balancer were about the same. Didn’t fit, so I will be using tape instead. Looks really good though.

Best buy! Fits perfect Looks nice Works as described Enough said
