Thanks , with the smaller base circle cam and stock 241 cylinder heads, 7.400 pushrods are they long enough ? what length should I buy ? Thanks again.

Probably 7.450" pushrods with stock heads and gaskets.

the 228/232 .588/.592 110+1 is the cam you and predator Z reccomended for my 01 Z06 which has STOCK heads. Based on what you are saying here, wouldn't I need a +4 advance than too?

Patrick G

Not necessarily. A Z06 starts off with higher static compression than an LS1 so you won't nead to advance it as much. Remember, what you get down low, you take away from up high. The correct cam is a balancing act.

If you were to err to one side or the other, you will get hurt less by too much advance than by too much retard. For a Z06, +1 or +2 would work great!

hey, Patrick,
just ordered the cam!!
thanks a bunch for the support!
this is what i ordered-
228/232, .588/.595, 110+2lsa!!!

i think the lobe for the 232 is with .595 lift, is what they said.

Patrick,

How hard would this cam be on valvesprings? I'm looking at some freshened GTP s2 heads with 918s. Trying to figure the best way to do this without redoing springs every year. I put 25k+ a year on the car so reliability is key. I'll keep the rev limiter to 6200 or so for that reason. How well would this cam address my desires? I'm also looking at 220/220 and 224/224, both on a 114.

Thanks,
Jason

LSK lobes are near solid roller in their ramp speed. As a result, you'll need to have very good valvesprings. Comp 921s or AFR 8019 springs are preferred and you'll want to shim them to within .050" of coil bind. You'd want to check spring pressure every 12k miles, but I'm not sure how long they'll last...long term testing is still going on.

If you want more mileage out of your springs and are willing to give up a few ponies, the Comp XE-R springs will give you more spring life. A 224/228 114 cam will give you very good street manners, but to get the low and mid-range torque up, you'll want to have it ground with 4 degrees of advance.

You mean to say XER lobes will give you more spring life, right?

Patrick G

iTrader: (14)

Nobody has come with conclusive evidence to prove that LSK lobes wear out springs faster than XE-R lobes, but since the ramps are faster, I'd venture to say that the LSKs would probably wear them out faster. Still don't know yet.

Hay, Patrick:

How much power did your Fast LSX Intake and 90mm TB give you?? I have a 2004 GTO M6 H/C and all supporting mods...all I have left is doing the Fast Setup. Just wondering what kind of power it will add??? Also, did you have your intake ported??

Thanks,

Chrissy

Those are some pretty healthy results. It would be a good test to try:
PSI 1225 springs ~175 seat and 465 nose
Trend 3/8" .135 wall pushrods

the 110LSA killed em on low speed tq.

when we say 110, 108 or 106 LSA we tinking increased overlap, blowby, etc.

But they always say the lower lsa brings greater low speed tq and a greater "on the cam" tq charge, and it looks to be true.

hey patrick, what would degreeing would you recommend for me for the 228/232 on 243 heads and stock gasket, . . would purchasing a thinner gasket be worth the money?? or could i jus degree it more to compensate, . . thanx!!! also, .. check your PM, i PM'd you like a month ago with no reply

stock cubes and stock gearing? looks like a cam I want!

Patrick G

iTrader: (14)

Unmilled heads? Yes, I'd highly recommend running a .040" Cometic gasket for higher static compression and tighter quench. I would then recommend 2 degrees of advance being ground into the cam (if a 6 speed). If you run an automatic, then you'll want 4 degrees ground in (to build more area under the curve and to avoid running too much rpm). Sorry if I lost your PM. I get 20-30 a day asking for me to spec them a cam. Takes a lot of time to do it right. Maybe I should start charging for advise...that would cut down on the PMs, LOL.

I personally think that you should write yourself a book. I don't think the majority fully realize the value of such knowledge being freely given by you. A regular David Vizard in disguise....
