Awesome cam for any street driven Silverado... Ive dynoed with it before and it performs extremely well!!! Youll need a set of beehives, I run the Comp 918s on this cam when I install it.

Better heads is always a good idea(see sic quote) but you dont require them.

Tq was 393 at 2000rpm so great for my heavy truck, if I get close to that I'd be happy. have been hearing bad things about those springs

You're prob not going to get 393 ft-lbs at 2000 rpm, but that cam is a good choice, especially if you upgrade to a higher stalling torque converter.

They had a few bad batches a few years ago, and totally redesigned the spring. You hear about one breaking every now an then, but thats because they put out probably 200,000 of those springs a year. THere is a certain percentage of failure in any valve spring, no matter who makes it. You just hear about 918s more, becuase there are WAY more of them out there than anything else.

I run them on my personal vehicle and put them on almost every street engine I install a cam in. The likelyhood of a breakage is very low.

110 = More overlap, more lope, slightly harder to tune, more bottom end

114= less overlap, slightly less lope, a little easier to tune, shifts powerband up a little.

Edit: I found my old dyno data on this cam!
