Broken valve spring dampers
#24
when I spoke to my machine shop about my springs breaking they told me a lot of the springs that break are from improper setup. I am not saying you didn't set them up properly but it is possible. Also like pointed out to me by people on the forum they are a ware ant tear part.

The PAC-1201 is same OD as the Isky with tons more rate. A big spring in IMCA stock car racing. Guys are turning over 7500 all day with that one. If your build is moderate the PAC-1200 has a little smaller OD with the same ID as the 1201 and has about 25lbs more open than the 235D.

Zebisko, If you're still looking for springs, I just installed a set of those PAC-1212X springs with the stock LT1 retainers and seats. They are a Huge improvement over the LT4 springs I was using on my Hotcam. My engine never revved so clean and strong to my 6k shift light with the LT4 springs. I'm looking forward to moving the shift light up to 6200 for track use. I bought them at sponsor Carshopinc.com, Tim over there had a great price on them.
