5ksev Posted December 14, 2011 Author Report Share Posted December 14, 2011 I'm kinda tight on cash, but iv found some for $150 from tighe.. Is that a decent price? Quote Link to comment Share on other sites More sharing options...
coln72 Posted December 14, 2011 Report Share Posted December 14, 2011 Umm, why?????? My 5k would pull 7500+rpm on standard springs. I know it would rev that hard as thats when the shift light would come on. Quote Link to comment Share on other sites More sharing options...
tunsafun321 Posted December 14, 2011 Report Share Posted December 14, 2011 the 202 springs are too big... i don't know where this comes from but its a sloppy fit at best. crow cams part number 4220-8, any part store should be able to get em from nasons engine parts.

The factory springs can't cope with that amount of lift. Quote Link to comment Share on other sites More sharing options...
philbey Posted December 14, 2011 Report Share Posted December 14, 2011 Horseshit. Mine ran for ages with .480 lift. Admittedly it broke a spring, after about 10000 miles. That fact in the FAQ needs correcting, it is not the case for 5k hydros at least. Get crow 4220s about 120 a set, delivered. Quote Link to comment Share on other sites More sharing options...

camerondownunder88 Posted December 15, 2011 Report Share Posted December 15, 2011 Hi, Heads up number is on here I have posted it before but off top of my head 5K valve springs are 9lbs more load than normal 3/4/1/2K springs. So if you have heaps of lift yes might die but wont be quick. And my stock 5K springs I run max lift a stock spring will take I got cam ground to .400" lift I have seen 7500+ and still going.......so id save the cash wait till you can get a good crow cam set done.
