I didnt notice no LS6 intake... chances are you probably wont hit 400 rwhp without one... the larger cams need to breathe up top and the LS1 intake kills them at about 6000... most guys make 15-18 rwhp adding a LS6 intake to a car that has a large cam!

I agree I have a ported LPE intake and it is better than an Ls6 intake.

On stock heads there is no chance of hitting unless you REALLY mess something up... I miss shifts once in a while just like anyone does and mine dont smack... I wouldnt worry about PTV... save your worries for your tires that will be begging for traction

thats what im talking about! my car traps 114mph now, i wonder what it will be after a cam like these? i guess ill flip a coin on the cams, x2 or x3.we are about to have emissions testing around here. i will have to see if is the sniffer or the computer scan. that will be the deciding factor. oh i wish you lived closer, i would love to ride in your car.thanks

I think everyone will agree 7000 is as high as you want to go... Valvetrain permitting of course!

And thats an absolute maximum. Especially for 98-00 cars with weaker rod bolts.

What all needs to be addressed in the valvetrain (and otherwise) to rev it out?

Comp 921 springs, Titanium retainers, Hardened pushrods and you are pretty well set for revs... Honestly most of the cars out here running the X3 cams are higher mileage cars so dont let people scare you into thinking your engine will blow up... then again thats also based a lot upon driver and the condition of your engine...

Like I mentioned in the other thread, I've got less than 15K miles.

So if I went with that comp 921 kit, i'd just have to get the pushrods? What about this double roller timing chain I hear about and LS6 oil pump?

Oh yeah...

What is the difference between chrome moly pushrods and the hardened ones?

What about lifters and rockers?

I can guarantee you that if you rev a stock bottom ended 98-00 motor'd car to 7000rpm repeatedly, you will blow it up...whether its a spun rod bearing, or an aerated block, it will happen...It's a mechanical certainty. 7000rpm is still too high even for an 01+ motor, whether its an LS1 or LS6. Just do a search for a user named SlyWS6...and he's just one out of a few lately. He was getting away with it for a while and then BOOM! Now if you install better rods/rod bolts then you'll be fine to 7500.

Yeah... I'm not too keen on destroying a low mileage engine...

no point really, all the guys around here run stock timing chains and stock oil pumps... I personally say dont touch the oil pumps... they seem to have a tendancy to go out if tinkered with!

lifters are under the heads, rockers are fine. Any type of hardened pushrod is fine, I like the comp rods for like 120 bucks

tell that to the 13 customers of mine that repeatedly hit 7000 using the G5X2/X3, including myself... your engine blows up from driver error, not mechanical. The vast majority of those 13 have over 50K miles as well

Dont worry about it... try not to miss shifts, dont launch at 7000 rpm, and dont take your car to the track every weekend. If you do those three things it doesnt matter where you shift, your car is bound to blow up anyways. The LS1 is a STRONG engine, however driver error can blow a engine whether you are at 2300 rpm or 7500 rpm.
