GMPP ASA Cam
The ASA isn't going to "eat" springs, don't know where that info came from. With a ramp rate of 56 and .525" gross lift, the '02+ ls6 springs will handle it with ease.
At minimum you'd need the cam, valvesprings, valvespring compressor, rods to hold the lifters up, timing chain (LS2 chain is cheap, works well) and the miscellaneous gaskets & fluids.....but then the "while I'm in here" line of thinking says there's no better time for a new ported oil pump...the crank pulley has to come off, why not put an underdrive pulley on? See where this is going?....

ASA= 226/236 .525"/.525" 110 LSA
GAC= 239/251 .570"/.570" 106 LSA
Definitely two different cams.

Why is this cam disliked, or lack of better word not used as much. I mean hell if its making close to 350rwhp/tq in the 2-3krpms you wanna talk about one hell of a 60' time. Other cams may perform a little better in the higher rpms but I cant honestly seeing htis one lacking up there.
Its making me reconsider my cam desicions. And that sound clip is just badass!!!

What I meant to ask was, what are the necessary things for the cam swap, not necessarily the tools needed for the job? For example, will I need new retainers? Or can I seriously just buy the cam, a set of 02+ LS6 springs and be done (or if I wish, hardened pushrods at stock length as well)? Oh, and the necessary gaskets and fluids of course. Also, why would I need a new timing chain? But I think I'm on page with you when it comes to the underdrive pulley...
Now I'm trying to keep the thread aimed towards everyone that would be interested in this cam, but I'm going to ask a few things that would pertain only to me. My car only has ~19.5K miles on it and is a '99 (car has factory oil pump). Would I be in need of a new oil pump for this cam swap? The one I've got definitely pushes out a fair bit of PSI (judging by the factory gauge in the gauge cluster). At full throttle, I'm at around 70 PSI or so and at idle a little over 40 PSI (all with the right amount of oil of course). So it seems that my oil pump is sufficient, but then again I have never owned a cammed car and don't fully understand what will happen to the PSI once the cam is in.

ok so i need to know the operating ranges of this cam... im looking to use this as more of a road racing cam... on 2.2 mile courses with max speeds reaching 120mph.. average speeds of 60-70.. with staying in mostly 3rd & 4th gear.. occassional 2nd with tight turns..
my rear gear is 4.11

But anyway, straight from where the cam is sold (HERE) it says that the operating range of this cam is between 2500 - 6500. So if you are reaching 120, you're going to be shifting into 5th occasionally to reach those speeds with 4.11's (not sure if that's a bad thing or what...don't know too much about road racing). Hope that helps.

Then again, I love my 4.11's now...they aren't coming out!

Here, I found the dyno sheet I was looking for.
I took that dyno sheet from this thread:
https://ls1tech.com/forums/showthrea...&highlight=asa
This thread shows a dyno sheet and all with the ASA cam. He made a comfortable 392 rwhp and 373 rwtq with these mods (taken from his signature):
'02 Trans AM WS6, M6, black/black
-Engine: GMPP ASA cam (226/236 .525 110lsa), Powerbond pulley
-Intake: Volant, !MAF screen, TB bypass, Baker smooth bellow, Bo White TB
-Exhaust: Jet Hot LT's, 3" Flowmaster TD's: (scavenger x-pipe, 1-chambers, turndowns)
-Misc: SLP shifter w/ Lou's short stick, Autometer cobalt gauges and shift light, NGK's, MSD wires, !CAGS !AIR !hood baffles

another quick question.. what about going to Harland Sharp 1.8 rockers.. would i benifit at all from it? what would this do, if anything?

Did I miss anybody?

Timing chains stretch over time, if you're going to remove it anyway you should replace it with a new one. The LS2 chain is a direct replacement and is less than $45. With such low mileage on your car, your oil pump is probably fine.....'98s should replace theirs, as they have been known to fail without warning.
But regardless, either I'll grab some more for myself or the guy that will be doing it for me. I also wasn't aware that the timing chain only costs that. I must ask why the LS2 chain instead of just a LS1 replacement, though?
