ke70_dyl Posted July 24, 2014 Report Share Posted July 24, 2014 So I found a 4k fs with a cam with .435 cam in it? What valve springs would suit this? Sorry for the noob questions not to familiar with engine work yet Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted July 24, 2014 Report Share Posted July 24, 2014 Cam grnders reckon 0.4" is the max for stock springs, but one of the Mods on here has run more lift than that with no problem on stock springs. Might have been Philbey- it was mentioned last year. Crow sell valve springs for higher lifts, or get Holden 202 off some particular motor. Just search Rollaclub for it, its on here somewhere.
