My information came from the people at Thunder Racing.. This is just what they have found from other customers cars with that cam.

But like you said its all about combination.

Can't go wrong with Patrick G/Geoff Spec'd cams, They will spec a cam that will optimize your setup you have and get the most hp/tq out of the motor. Let them know what your goals are and im sure you'll be better off.

very good choice going with those guys...

The op may want to read this thread as well, it may be a bit older, but has lots of good info.

LMAO with daily driver and recommendations of T-rex cams....

Stick with 230 and under. The cam I'll likely go with for my DD and possibly a set of 243 heads will be around 228/232. EPS has a nice 222/226 and 226/230 cam thats a great driving cam that makes big numbers. Others can do that too. I've seen cam only cars with over 235 deg duration only make 400whp when some of the smaller mid 220's cams are only 5-10 hp off but make a crap load more power under the curve where it counts. If you go heads down the road, you can make 430-450whp easily with the right smaller cam and supporting bolt ons.

IMO you should do heads/cam at the same time as the cam has to match the heads and setup the pushrods and valvesprings on the 5.3 heads you get for the cam you use. No sense in using pushrods/springs in stock heads and then swapping over to different heads and having to get new pushrods and swap over springs.

EDIT: Thread posted above is exactly the reason. Keep dynamic/cranking compression high and you will make good power all over the curve.

The things you NEED to replace are; pushrods, springs, and the cam obviously. Everything else is optional. But it's good to replace things while you're there... like the timing chain, and oil pump...
Not true. I had an MS4 with stock 241 heads, LS6 intake, Mac Mid Length headers and had absolutely 0 surge. Pat G got the tune spot on but spent some quality time doing it.

I have some surging now, but thats because I have a 408 with 799 heads with the same intake/exhaust (read: choked motor) and we didn't spend near as much time tuning because it will change again and again and again as I change the intake, heads, exhaust, FI, etc.

With that being said, a donkey dick cam isn't for everyone and that's not what I am advocating. I am definitely not one to recommend a cam but will point out the fallacy that all big cams surge.

Same here it's all in the tuning .. Sam did mine and it drives perfect. David is getting Sam to do his so your good to go.. Also ask Sam what kind of cam might be good to if you want.

I did say little to no gain just like the people told me at TR.

David how soon are you looking to do your cam? Depending on what your goals are, I would go with a custom grind spec'ed to your likings..

I did say little to no gain just like the people told me at TR.
show me a forged cam only shortblock that is even remotely close to those numbers. Its like one of those myths that 1 7/8 headers are too much for a 5.7L or that a Fast 90/92/102 doesn't make power on cam only 5.7's.

It being an A4 doesn't make a difference, there are plenty A4 TRex cars out there.

M6 will make more power over a A4 any day.

You also have to count all his other mods to get him to his 490 range.

I just think its funny.....Your trying to prove me wrong when, I'm not the one saying this the people that made the cam are saying this.

I'm not saying this cam is **** or anything I'm just saying ....if he wants to do heads/cam there are better cams that TR makes to get him the best bang for his buck.

If you want to call TR and have this talk with them have at it .. I'm done...

You might want to show TR that guys car so they can put him down as a point to prove what your saying.

Go with a cam in the 228-232 duration range. Anything bigger will require more converter and gear than you would want to put in the car.

Do not buy a t-Rex or ms4 cam.

U will have a nice set up with 5.3 heads and a mild cam and a SAM tune. Im bout to get some 5.3 heads my self and do a budjet head but im going to do a lil more research before this. I will probally sell my cam and do a Pat G cam matched with my mods and the 5.3 heads. The thing bout TREX i know cuz i was going to go this route at first and called TR is that if u do heads u have to cut valve reliefs with this head u cant mill the heads at all and u got to watch the size of the valves cuz alot of aftermarket heads with bigger valves have thicker valves which presses ur luck on ptv. So u can do heads all day long with a trex but it will cost more in the long run to cut pistons and such. I would like to get some 5.3 heads and put 5.7 valves in them and maybe clean them up a lil. After alot of searches it has been said they flow the same as 5.7 heads after u switch the valves and u get the compression bump

Notice that the list is dominated by small cams. Just because someone doesn't set their car up correctly doesn't mean all cars with a big cam will be turds. Some people like smaller cams with better "drivability" while others don't.

There is no right or wrong in choosing a cam as everyone has different standards. To say that a TRex won't benefit from a fast, better heads, or bigger headers is ignorant.
