Mods......should I re think....
OK, this thread got me thinking..
http://forums.corvetteforum.com/show...1786796&page=2
I purchased the Super Ram, I purchased 1.6 rockers, springs, ect... based on forum advice.
Now, I really don't mind doing the work, but am I going to wind up like the OP of the thread? I'd like to end up with a car who's power band is similar to stock (which is shy I'm keeping the cam) but just more of it.
After I do the intake and rockers, LT headers are next, with dual high flow cats.
With the Super Ram and LTs am I giving up a lot of torque.
I already have a "high performance" chip, which I will have tuned specifically to the mods when done.
Thanks for tolerating my paranoia......

If you go with a superram setup, then you need to use the correct cam and tune to fully benefit. From my post in there - the OP is already 0.2sec and ~5mph faster without any tuning or shift point changes. There are definately gains to be had, but it will not feel the same (torque) as a long runner setup.
FWIW, My setup has an almost stock powerband - TPIS big mouth with runners and ported plenum, iirc AFR 180 heads, TPIS 288 cam, TPIS long tubes, Borla /w dynomax mufflers. Supposedly around 350hp/420tq, looks almost stock, smogs fine, and runs 12's.

I've been following your posts a bit. The Scorpian rockers have got bad reviews from what I have read on here. Did you find them in a seach at all? Get 1 5/8" headers instead of 1 3/4". A new cam would be better suited to the setup then stock. There have been many great running SR cars on the forum, there have been some dyno charts posted but I didn't save all the links.
I don't want to get into a state of paralysis by analysis.
The SR seems to be more suited to low-mid RPM ranges than does the MR. That's why I went that way.
I know a cam would do wonders, however, I am not about to do all that work. I am going to install the SR and rockers, run it, then do the LTs this winter or in the spring. I can only spend so much money at one time. I have a boat too, the wife starts to b*tch...
Followed by a torque converter and shift kit.
I recognize that my weakest spots will be the heads and cam. But that's a lot of money and work. I've done it before on other vettes (C3s I've had) and it's a bitch. Serious.
I'd rather ask the questions now, then have to do it over later.

What I may consider instead, which is actually MORE expensive, would be some forced air. Perhaps a Vortex or Procharger. That would bring the torque back.
I want to get this other stuff done first, as long as I'm not making it WORSE.
The car runs like a top as it is. Just tuned it up and got it tuned by Corvettes of Westchester.

The heads and cam I'm leaving until a future date. I just can't see dropping $2K on heads and cam when there's so much other work to do.

Sounds like you know what you want
. I think a supercharger would be a good way to keep the powerband similar, but I wouldn't personally do an intake change without a matching cam

You wont end up like him if you do some tuning, which he obviously hasnt. I would not be surprised if you have some dead spots in the band, which is part of his problem, but you will probably always have that until a chip is done and theres no point in doing that until the cam is changed.

the SR kicks in nicely at the lower-mid rpm range all the way up, that is to say it starts shining at about 2,800-3,000 rpms. your rpm range with a SR will extend from 4,400 to a more respectable 5,500-5,800 rpms. this is why you'll want a cam/heads package because that's where your power is really generated. oh, also you'll notice with the proper cam, you'll actually experience two power "peaks", one earlier and one later in the extended powerband.
vader is right.....you'll need the chip re-calibrated, and if i were you i'd wait until you can everything at once.

From what I understand, the L98 responds well to intake and exhaust.....I was just going to throw the rockers in since it's easy while I'm there.
I also understand that the Torque converter and shift kit will also help.
That's about as far as I can go before I get to the "big stuff".
I know the heads would be a peice of cake with the intake off, however, that's another $2k I can't spend right now. Like I said, boat+wife=less mods.
SO, do you guys think I'm going about this in a sensible manner. If it's an all or nothing, I have to do nothing....
Whatta ya think?

There's nothing wrong with doing your heads and cam later. I did my SR, 1.6 RRs, downsized pullys, 52 MM BBK TB, downsized pullys, catbacks, Transgo shift kit and cold air intake. I still have not touched the heads and cam. It's getting a little faster all the time. Gears are next. I do things when I have some extra money and time. Works for me.

I dont see any problem with doing it one piece at a time, thats pretty much how I work on my car.
But dont be upset when things dont magically improve like the poster in that thread.

I hate doing cams, in the car. And I'm not about to pull the motor.
I figure at some point the heads will have to come off resulting from a blown head gasket or something, THEN I'll do the cam....

I got some paper work with the car when I bought it. One says R&R tranny and B&M torque converter installed. On the line I tried holding the brake while I built up RPMs. It worked too good. I thought it would never hook up and my times were terrible. I had a 2.2 60' and a 14.0. Trap speed was 97 MPH. With the right gears and some traction I should be around 13.5. I have 2.73 gears right now and street tires. When I get to the Lngenfelter 211 cam I should be low 13s. Yesterday I installed a 2 1/2" front Y pipe with the pre cats eliminated. I took it for a ride. It is a little louder. With the pre cats I had some hesitation. It felt a little quicker. I think the 20 year old pre cats were a little clogged and the 2 1/4" pipe restrictive. I like doing things to my Vette on weekends. It's a hobby.
