cam question
 

how many people are running 60lb valve springs with a stock camshaft?

My 98 is, why?

I know of 4 right off the top of my head in my town running stock cam and 60lb springs.

Yeah... I don't understand what the problem would be?

Maybe added wear to the lobes from the higher pressure? :humm:

anyone thats running a 4kgsk or higher!

Nothing at all wrong with running them on a stock cam, but pointless to use them unless your going to start spinning the engine much over 3000rpm

you need the springs for exhaust breaks, the reason im asking is becasue when we pulled the cam the intake lobes were excesivly worn enouph that they were pitted. im buying a new cam but i was wondering if a stock cam can handle the stress of 60lb springs

Plenty of trucks do. Any truck with an exhaust brake uses them, and any trucks spinning over 3200 rpm are supposed to as well. Thats a lot of trucks. You'll be fine.

ok i was just wondering because all the aftermarket cams say they are rated for 60lb springs so i didnt know if thats why mine is worn so bad or if it is just the 300,000 miles taking its toll

y not go w/ a better cam? hows the engine comin along anyway?

Man I'm good... :tttt:

if your getting a new cam get a schied street performer itll bring down egts and give some more power well worth the money and not too expensive iirc

the engine is coming alot just waiting for cam ideas. the reason im not to thrilled about a upgraded cam is because of the price ive already spent way more on this than i have in my account

yea that is typical with about every project... sucks

yea I know how the running outa money thing works I do it all the time lol but one thing that was nice bout the schied street performer is that its only a regrind so its not as bad

i wouldnt put a regrind in my truck if my life depended on it, thats like running anything but synthetic in my truck, i just ended up buying a stock replacement cam for it since it has as much power as i want

If you would have got a different cam for it would that mean you have to have cut pistons to clear the valves then?

not that i know of ive never herd of it

I thought that any truck with a manual tranny already had the 60 lb springs so a jake brake could be added. Seems some after market springs go higher yet. Just my thoughts.

are you going to replace your lifters?


Not all aftermarket cams require fly cut pistons ... it just depends on how big you really want to go:c:

Not trying to steal his thread, but yes he got new lifters to go with the new cam. At least that's what he told me. :up:

good next question ... HD pushrods? while your there, might as well much better than bending one

nope hd push rods aint worth the money becasue they will still bend, stock ones will do just fine

I disagree with that ... but it is your truck so do what you want

i will do what i want, ive had multiple guys tell me that its a waste of money because they can still bend 3 months ago when i bent my push rods putting my new head on. if the supplyers say there a waste of money then thats a good enouph awnser for me

who's pushrods did you bend?

hmmm... my cam gear broke and almost all the valves hit the pistons and the stock rods were still straight.... Guess I just got lucky.

i bent the stock pushrod because it wasnt in the lifter completly in novermber when i replaced my head, when the owner of a diesel performance shop tells me that a hd pushrod is just as easy to bend as a stock pushrod im convinced it aint worth a dime

interesting, when I do my cam swap I'm still upgradeing my pushrods

go for it but im saving the money for something bigger and better
