Car is a 2000 trams am M6 with headers, exhaust, lid and 373 gears.
The car is not a daily driver but a weekend pleasure car with occasional dag strip usage. Im going with a heads/cam upgrade. Looking at LS6 ported heads and the cam to make well over 400whp...
I am thinking of the cam being around 230/230:
TR 230/224 .575/.563
Texas speed 231/237 .595/.598.
TSP Torquer v2 232/234 .595/.598
Speed inc S15 231/237 .589/.595
Comp 228/230
Comp 231/237

Which of these or other recommendations would you make?
Also what lsa would be best for streetability but still lots of mid and high end power?
Also, is it true the reverse spilt cams dont go well with aftermarket heads like the tradionals do?

I suggest the 230/224. I don't think I've seen even one car with that cam that ran poorly. Very strong street cam that is daily drivable.

the purpose of those reverse split cams are to hold the intake valves open longer, so that it can make up for motors w/ stock heads and intake to flow better. thats why reverse split cams are popular with stock heads and a free flowing exhaust. as for how they perform with a set of heads, i dont know, mine are still stock. but im sure somebody will chime in and let you know.
But personally i love my Tr230/224. Great midrange torque, and makes great power(see sig for numbers). After the tune, the car drives like stock, but still sounds mean as hell and has a nice lope at idle. I think its a great DD cam, and i drive with it everyday.

The intake is a bigger restriction. Also, the exhaust does NOT have to be that great on the 230/224. The cam doesn't have that much overlap, and will work well with only a *decent* exhaust.

The 230/224 responds well to ported heads. Just make sure the exhaust side of the head flows good too. If the exhaust/intake flow ratio is the same as a stock head there's no reason for it to not make awesome power with ported heads.

Will the reverse split style perform as well with the traditional style cam with ported heads though? Or would I be better off with a traditional style cam with aftermarket heads?

It will perform as well. Some might argue you'd be better off with a traditional split if you were running a FAST intake, but even it is still restrictive compared to a nice single plane intake.

Well down the line I do plan on a FAST intake and ported tb. So I should have a full and very good flowing intake and exhaust system...will that make a difference?

do a little research. Use the LS1tech search for "reverse split", they have been talked about and compared to traditional split cams quite a bit around here. There's a bunch of good information that will help you make a decision.

BatmobileWS6

Ok thanks i'll search the reverse split.
My other main concern...the lsa. I cant pinpoint what seperation angle. recomendations on that?
Considering I want a decent idle but like the lobe sound, decent response without too much surging down low (I'd say most of driving is below 2500 rpms), although I do want high end power but without comprimissing too much down low? Haha I know all of that is impossible but would like the best to fit that...

the 230/224 is on a 111 lsa. it sounds very mean at idle, and i can still cruise at 1800 in 6th when i need to with no surging at all.

1. TR230/224 - good cam, solid numbers
2. TSP 231/237 - Old design, lazy lobes - not so solid numbers
3. TSP Torquer V.2 - Great cam, Solid numbers (my recommendation from the list)
4. Speed Inc 231-237 - I am pretty sure its the TSP with a newer lobe design
5. not sure
6. not sure

My advice: Don't gamble or experiment. Go with something that is a proven performer. Don't go with a MS3 or MS4. They are overrated, bad compression ratio and poor torque.

Drivability and surging will be dependent on how well your tune is.

I am going with the Patrick G Donkey cam which has been called the "G5X3 camshaft on steriods". It makes great power and great torque down low. I will be getting it in a 110 LSA to bring the powerband down.

Good Luck!!

I went with a custom grind 232/238 with ported ls6 heads and full boltons and made the numbers in sig. Car is still very streetable. Down low under 2k it feels like it lost a little power, in the 2k-2.5k range power is about the same as stock. from 2500 to 4500 power is defintely up a good amount and the car feels much stronger in this range over stock. And finally from 4500 to 7000 the car is totally crazy. If the car isn't your daily you should definitely go with something in the 230+ range.

232/228, .595/.588 111-1 LSA with a nice set PP or PRC or Livernois, stage 1 243s and maximum compression.

LG's G5X1 cam puts out nice numbers, even if you get it on the 115LSA. It's a 228/232 with lift in the high 0.5xs. A member on corvetteforum.com has that cam with AFR's, and with a FAST 90/90, he was at 470whp. I believe a couple of other guys were running with LS6 intake, and hit 450. The user's name is Switchbarrel. I believe he's on this forum as well...

I think i've pretty much narrowed it down to the 230/224 .575/.563 111 LSA and the TSP Torquer v2 232/234 .595/.598 113 LSA. Just have to figure out which cam will be best suitable for my setup.
What will be the difference I'll notice? and the difference in the 111 and 113 lsa?
Will one or the other work better with the ls6 ported heads, and full bolt ons?

BatmobileWS6

I think im pretty decided on getting a package from texas speed with the TSP Torquer v2 232/234 .595/.598 112 LSA and PRC LS6 heads.

I have the same cam with out the heads and love it! It drives about like stock, and has wild top end also.

How does this compare to the 228/232 111(or 110) that was was being heavily recommended not too long ago? Is this a better choice now?

What's the specs on that Donkey cam?

BatmobileWS6

I've heard nothing but good things about the Torquer v2! Which makes me happy considering im ordering it soon. Soonest install date I can get is May 7th thought : (
I wanted to wait to get the custom tune until next year when I get the intake manifold/ported tb and possibly nitrous.
But with getting the Torquer v2 and heads installed...should I get a custom tune?

no bro, with a camshaft that big and heads you will need a tune asap. a retune usually costs like 100 bux after so jus get it tuned . . . oh yea, i forgot to tell ya in my previous post: cool screen name
