Does anyone know what letters/numbers are stamped on evo 9 stock cams? Please let me know

 

So many options lol

 

this is so awesome! i wonder if there is one of these charts for valvespring options for the 8/9 evo's.

 

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

 

I've been really impressed with the works 280 cams.

 

I'm going from stock Evo8 cams to Kelford 272s in 2 weeks.

 

Also try gsc s2. seems good!

 

Thanks for the spreadsheet!

 

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?

 

Tomei Type-R's, just worked out their full specs from the basics supplied by Tomei.

wow those 284HL cams are as big as i have seen period.

 

Are you sure about the stock 8 and 9 cam specs? The other thread states 260/256 and diff lift for the 8.

 

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.

 

Still coming in handy over a year later. Thanks!

 

Hi!
