zmaster Posted February 17, 2008 Share Posted February 17, 2008 Can I run this camshaft with a stock 280z??? http://cranecams.com/?show=browseParts&lvl=4&prt=2037&action=partSpec&partNumber=168-0014 and would it be better to use these valve springs with this cam or can i use the stock springs? http://cranecams.com/?show=browseParts&lvl=4&prt=2019&action=partSpec&partNumber=99884-12 Quote Link to comment Share on other sites More sharing options...
RedNeckZ Posted February 17, 2008 Share Posted February 17, 2008 I have the same type cam in my Z right now. It is a great cam for a daily driven Z with triple carbs on it. I put on the springs and retainers. Good Luck with what ever choice you make. Always look at the way you plan on driving it and then make your choice to fit your driving habits.

Administrators BRAAP Posted February 17, 2008 Administrators Share Posted February 17, 2008 Any cam with any amount of lift/duration greater than a stock cam should utilize stiffer springs than stock! This is not to say you can just pick any old stiff spring and use it. The springs should be “matched†to the cam. The cam manufactures recommend a specific spring for a reason. It matches that cam and its intended usage and RPM range. Follow those recommendations. In short, if you get the cam, get the matching springs. Also, if you are using the stock EFI, do yourself a HUGE favor! Do NOT install any cam other than a stock cam with the stock EFI! You will make more power and have better drivability with the stock cam when using the stock 280 EFI! Now if you plan to use Mega squirt, or some other after market EFI and you want more upper end power, then by all means, more cam, but don’t do it with the stock EFI. You will end up with less power (at best equal peak power), and have flat spots and hesitations all over the RPM range at different loads that you can NOT tune out or around. Also, the stock EFI intake manifold is not a great serious performance intake. It works great with the stock cam for mild applications, but if a more radical power-band is wanted, some form of alternate intake manifold should be on your list. The stock intake runners are only 53% the size of the intake valve itself in square area! Almost HALF! Good luck, Paul Quote Link to comment Share on other sites More sharing options...
