Felix Posted May 17, 2006 Report Share Posted May 17, 2006 keep in mind that for any given cam, the power range will start and finish about 1000 rpms lower on a 5k, as compared to a 4k. Quote Link to comment Share on other sites More sharing options...
thomo Posted May 17, 2006 Report Share Posted May 17, 2006 mind the camtech cams friend has one turn up without the hole in it for the pully locating dowl, to fix it the camtech guy held it in one hand and bored a hole in it with a cordless drill, got to wonder how exact they are!

Felix Posted May 20, 2006 Report Share Posted May 20, 2006 (edited) thanks. geez, they are not very generous in the lift department. how does it go in your engine? Edited May 20, 2006 by Felix Quote Link to comment Share on other sites More sharing options...
madrolla68 Posted May 20, 2006 Report Share Posted May 20, 2006 thanks. geez, they are not very generous in the lift department. how does it go in your engine?

Felix Posted May 21, 2006 Report Share Posted May 21, 2006 (edited) the bigger grind you have listed has only 0.360 thou (gross) at the valve.... i sort of think they should have bumped up the lift for the translation over to k series. a 5k just doesn't have anywhere near the valve curtain area of a cosworth 4 valve head. anyway, hope it works for you. :) Edited May 21, 2006 by Felix Quote Link to comment Share on other sites More sharing options...

Felix Posted May 21, 2006 Report Share Posted May 21, 2006 fair enough, probably help even things up. what type of valves have you got in there? sizes? compression ratio? Quote Link to comment Share on other sites More sharing options...
chrisandliz[RL] Posted May 21, 2006 Author Report Share Posted May 21, 2006 so will that make much diffrents with my standard head? Quote Link to comment Share on other sites More sharing options...
madrolla68 Posted May 21, 2006 Report Share Posted May 21, 2006 fair enough, probably help even things up. what type of valves have you got in there? sizes? compression ratio? Not sure on the exact size but there is like .030" between the two valves,the comp ratio is only 10.5 to one. Have you run the cam on the DYNO2000 program Vs other cams yet like the CAMTECH 609.
