does anyone have any info on a better product. as posted below in another thread, during my time on the dyno, we were limited to the amount of timing i could put into the engine because the valve springs would start to fail at 6850 and full float at 7000rpm. i am running a hydraulic cam 430 lift. we are running a bee hive sytle spring now and any help on part numbers or brands that i could do some testing with would be appreciated.
Thanks Ian Last edited by Ian Hill; 03-08-2009 at 03:19 PM. |
