Cam Question?

[12secondCRX]

When you first install cams and the rest of the valvetrain how long do you need to let it break in before you really get on it? I was told to wait for about 1000-1500 miles.

yes good question, im looking for crower 403's with springs and retainers and i am wondering the same thing.

cams dont need to be broken in.

 

[pills_PMD]

neither do valve springs / retainers... let those bitches spin@!!!

Thanks for the help!!

1 more question to do with this thread, if i get crower 403's with titanium valve springs and retainers, what COULD i rev it up to? is the block able to hold 8000 shifts? or should i keep it at 7200? ( right now i shift when racing at 7000)? any1 know?

shift where you stop making power.

if i get crower 403's ill stop maknig power around 7700, can the LS block with titanium springs and retainer hold that?

you'll probably end up with a spun rod doing that. The ls bottom end doesn't have the most desirable r/s ratio to be revving to 7700.

i wouldn't say that. get some ARP rod bolts then you should be ok. r/s ratio doesn't have that much to do with it.

Rod/stroke ratio really doesn't have much to do with the integrity of the B18A/B bottom end compared to the B18C.

 

[liquid00meth]

oh. I thought someone had said the different r/s ratio wasn't as desirable for high revs. Didn't really know why.

 

[phunky.buddha]

Don't worry, I have an article about that coming up too. Side loading is less than 3% greater with 1.54 rod/stroke than it is with the 1.58 of the GSR engine. It's not significant.

How far can you safely rev the ls motor if you have Eagle H-beam rods and bolts.

id say 7200-7300 is the tops u can push a LS. i rev my stock LS to 7000 when racing, and will up that to 7200 once i get Crower 403's with titanium springs and retainers. u wont make any power after 7200 without cams, and u cant rev an LS over 7400 before it gets iffy on the block/head holding.
