schrick 284/272 - what valve springs?

[racecar]

hi guys

for those who run the 284 - did you use schrick springs or just the stock ones?

possibility i have valve bounce - just wanna know what others are using before i have a look

cheers ross

As far as I know if you upgrade the cam then you should upgrade the springs too. Stock ones aren't designed for a Shrick cam.

I upgraded to the Schrick springs. I don't think the stock ones cope very well with the extra lift of the cam.

Possibly off-topic (ever so slightly), but I have a 304 schrick cam, and my mechanic absolutely REFUSED to put it in without upgraded valve springs! Then again, 284 is tamer. I'd put them in regardless, better safe than sorry I suppose.

thats a non road car spec cam, must be wild when that kicks in.

yes the valve springs are a good idea imo

Some people use them some dont - never heard of the normal ones failing.

I know of 2 engines without them useing the same cam - they get driven very hard and nothing gone wrong.

284 is quite tame.
