Need new harmonic balancer for supercharged 302

I took a look at my current harmonic balancer and its looking pretty rough, definitley think it would be a safe idea to get a new one since I don't want to grenade my engine the first time I take it out.

What are everyone's suggestions for a good VALUE balancer. I don't want the cheapest or most expensive. Say under $300 what is the best value balancer I can get without risking my engine or bank account lol

Put that exact same balancer on a friend’s v2 fox body a couple days ago. Fits really well.

On the topic of pullies, and maybe taking this thread for a turn. I can't use the 6-rib crank that came with my Sci kit since I have a 93 cobra crank, so I need to get one of those all-in-one pullies for the serp and blower. What pulley do you guys recommend? I was going to buy the 8 rib package for my car from Vortech and have read that the 8" version makes the blower very responsive and honestly, I'm intrigued.

Open to all suggestions within reason of course. Not looking to push 18#s of boost as it is completely stock and the heads are obviously a massive restriction. Would the 8" crank put too much stress? Should I stick with the 6.87" crank from Vortech?
The 93 cobra crank is just a regular 5.0 crankshaft.
I’d just stick with 8 rib. You can reliably make 600whp+ with a 8 rib setup.
You have a Sci with heritage gears?

Why would you want to overdrive the crank?
Larger crank pulley also allows smaller head unit pulley, which is beneficial on a ribbed setup.
Would a larger crank pulley not allow a larger head unit pulley since it would be spun the same speed while maintaining beltwrap?
Yeah that’s the benefit of the larger crank pulley. You can do a smaller head unit one and gain more belt wrap.
Wouldn't you get more wrap only on the crank? The head unit would still spin if there's less surface area and its being spun faster now
I don’t know why I said you can do a smaller head unit pulley, I meant larger to maintain the same blower rpm which will allow more surface to grip.
