i am about to purchase some crower #62403s and some valve springs and retainer....the one i had in mine was
68181 dual, 1.105 o.d. this goes for $185.95

but when i saw the cam on groupbuy it said the cam shafts required a set
84162 dual spring and retainer set this goes for $300shipped

so i want to know the difference between these two items both from crower.

Your question confuses me but if you want to know the differences between the two valvetrain part #'s than here it is.

84162 - complete valvetarin kit(springs and retainers)
http://www.crower.com/cgi-bin/detail.cgi?prod_id=84162

68181 - valvesprings only
http://www.crower.com/cgi-bin/detail.cgi?prod_id=68181

The difference is the 84162 is the complete valve spring and reatiner kit. And the 68181 is just the valvesprings themselves.


Both have the exact same coil bind measurements,wire diameter,.OD/ID, etc.

Rev up to 7500 rpm it's pointless to rev over that cuz you have lost so much hp&tq . Ive never seen a Dyno of 403s making good power around 7500. Also look into a AFC unit.
