Last summer I switched from HKS 280s to Kelford TX284HL cams in my stroker. The Kelfords made a nice difference in power.

I have a question, will i have to upgrade my valve springs for the kelford 272's in order to run them if so, what would be the best ones to run without having to upgrade them?

5 months later and still very happy I went with the Kelford 272s. Between the retune and the cams, I picked up like 46hp/40tq on a mustangdyno over the stock 8 cams.
