Ive had a TR224 in my car for years and several motors, I moved into 6.0 country last year, and I feel the 224 is just too small and im leaving a lot of power on the table.
6.0 LQ9
Cleaned up 799's
TR224 (224/224 .583/.583 112LSA)
PAC 1518's
LS6 intake
Longtubes and full exhaust
4200 converter
Car made 390hp/400tq last year on a dyno thats not very friendly if you know what I mean....
Someone local has a very lightly used EPS cam for sale that I think would be a good fit, but I dont know a ton about these cams.
The cam was custom spec'd by Pat G for this other guys car, but seems like it would be a decent fit for me as well. Hopefully Pat G will chime in and verify that.
Custom spec'd EPS/Pat G(230/234 .600"/.602" on 112+4)
I still drive the car on the street almost everyday in the summer over 20 miles one way to work and would love to retain that driveability.
There is also a wet plate kit with the 100 jets in it waiting to go on the car if that influences the cam decision or not....

Im not expecting to gain a ton, thats what the spray is for ![Happy](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_stretch.gif)
But the question is if its worth the work to do it. I would definitely like to see "results" if you know what I mean. I would really expect 400 to the tires.

Power under the curve, seems that thats the results people are seeing lately with these cams. Also the far superior lobe design. The TR224 is a great cam, but is old and dated. Technology has come a long way since that puppy was ground.

I gained around .2-.3 and 1-2mph (inconsistency in passes) going from a 230/224 and stock heads to the 230/238 EPS and hand cleaned up (bowl work on intake, sanding roll on full intake/exhaust) 799 heads.
On the street, the changes feel huge in the low/mid range though. I was expecting to see closer to 5mph gains due to the way it feels.
If you're looking for a real fun street car that won't see much track, it might be worth it. If you are looking for big ET gains, look elsewhere than a cam swap.
Your experiences may differ but those were mine.

That's an outstanding cam choice for your combo. It would be worth the change because you'll see some incremental increases in power NA and even bigger gains on nitrous.

Not based on my current results, what would you expect to see out of this setup on the dyno? Seems like 400RWHP should be easily in range?

If your new heads are milled a little or you use a thinner gasket the 7.4" might actually be perfect.
I had my heads shaved .010" and used Fel Pro composite type gaskets. I am running a Vortec 350 SBC style lifter which likes more preload, but the 7.4" are perfect for me with .110" preload.
If you are running a stock ls1 lifter or ls7 lifter you might be on the high side of acceptable. I would check them to be safe but chances are good you will be ok.
