In the testing below the LS6 was worth 22 hp and 15 torque over an LS1 intake on an engine dyno.

Yeah I'm gonna do an LS6 intake when I do heads. Still undecided about heads either sending my 862's out to Texas speed for there 2.5 stage build or buying Thompson motorsports ported 243's. The Texas speed has a better flow rating and was told they would perform better
Those heads you showed on your other post look beat. How deep is that gouge in the face? And what happened to that one intake valve? Hard to say what that seat is like considering the valve lost some material. Go with the Thompson deal. It is better all around.

Talked to Texas speed about the scratch and they said it was no problem the valve part was what I was worried about. And I was looking at the stage 2.5 5.3 heads flow better then the Thompso's ported 243 heads. Still up in the air and can't make my mind up with it.

The Texas speeds are like 20 dollars cheaper after factoring in shipping there and back. The only reason I want the Thompson's is to eliminate the whole shipping thing. I guess Thompson's is bumping there price up a few hindered dollars in the next couple of weeks but said they'd still give me the original price when I go to order it if they rasie them by the time I order them

It's starting to sound like there's maybe a little less hassle and risk with the TMS option

Yeah it is. I just liked the fact of having brand new valves and better flowing. The TMP's use remanufactured valves with there 243's and to get stainless steal it's an extra 240 bucks lol
I totally understand where your coming from and the indecision that exsists. Money, choices, and excitement all play factors. Do your best to come up with a solid plan and stick to it. Things will fall in line.
Regarding the TMS 243's..by remanufactured valves, do they mean re-using the exsisting?
Personally, I would go with the stall before the intake. Even though your stock stall could handle the smaller cam for now, a higher stall is a very impactful mod-Regardless of street or track. In time, like HCI stated, maybe you could bypass the LS6 intake purchase and head straight for the FAST. From the classifieds should save you some coin. Not trying to sway your choice, just food for thought. Good luck.

About the remanufactered valves im not really sure all they say it's remanufactered valves or you can upgrade to stainless steel for 240. But the reason I wanna do the LS6 intake now is 2 reasons. 1) the LS6 intake and heads will probably be the last engine mod that I do to the car honestly and 2) I'm scared of just getting heads only that I'll get the dyno numbers back and I won't be as please with just the heads without doing the intake. I know you guys all say dyno numbers don't mean anything I know that but it's nice to shoot for a number and achieve it so I can tell people what it puts down to the tires. I don't take the car to the track often at all maybe once a year it's a street car basically. Car put down around 380 trying to get in the 410-420 range. I can use my stock stall fine and I know a stall would be better than a intake but kinda on a budget right now and a LS6 intake is cheaper than a stall and labor is cheaper sense the intake is coming off when the heads do. Hopefully you guys get where I'm coming from!
Definitely understand where your coming from. As do the others I'm sure. If your budget allows for the intake over the stall, then by all means.pick up the ls6 intake. Fortunately for you, you have that wiggle room on choice because of your smaller cam. Your convertor is OK for now, which allows you to lean towards an intake when considering budget. Even though its your thread and specific application, we still feel compelled to give advice and opinions that lean the general modder in a productive direction. The majority choose a larger cam, in which a larger stall is pretty much a requirement. Much more than an ls6 intake. You will be just fine. Be sure to watch your fueling requirements as you add power. Hope everything turns out well. Just letting you know where we are coming from.

I completely understand where everyone is coming from I know I could of gone with a bigger cam but I just wanted the biggest cam I could get that I could use the stock converter. This is just a mild build nothing crazy at all just something fun that still has a lot of power. I'm planning on getting a 6.0 block in the far future to completely build from crank up. So when my ls1 gives I can put the 6.0 in it. Do you know how much power the stock ls1 injectors and fuel pump can take?
My point was geared towards the decision between stall convertor or Intake, not your initial cam selection. Your cam selection is perfectly fine for your own needs. As far as fueling, it varies a bit. It's always a good bet to upgrade injector size and a fuel pump when getting into H/C/I territory. A datalogger like HP Tuners is a good tool that helps but not required. Check out some of the stickys in the fueling and injection section. There is plenty about injector duty cycle, fuel pressures, and the like. Take it easy
But it may be worth a few horse.
