Try Isky or Comp cams. The will make you one. I would call them and talk to the tech guy about what would best suit your needs. That's what I did. I went with an Isky cam kit that included cam,lifters,double springs,reatainers,and polylocks. With these springs though I had to get the guides machined down so they would fit. Something to consider or ask about. Good luck with the car. It's nice to see another pacecar hitting the road.
