I don't know what your monetary situation is as a student, but based on the fact you're running a 93 LT1 and remembering what my situation was when I was at TAMU, I would build the Scat 9000 383 with 6" rods and have it balanced by your engine builder. I would then talk to your head guy and get a cam recommendation from him that works and put some valve springs on it that you know are good.
I would then tune the car to run right and consider shifts at a more reasonable area like 6 or 6200 and set my fuel shutoff around 6500.

You'll have nothing but hell with that thing if you run an oversized cam in it and spin it like its a destroked LS7.

I would also keep the oil cooler. Build an efficient small block that stays cool and runs smooth and you'll have plenty of fun with a car that makes 400 RWHP and never lets you down. Don't get greedy and put NOS on it until you're out of school and are financially sound enough to tear it up because that's what will eventually happen. By then, you'll either have enough money to build a real, no-holds-barred engine, buy a new car, or you'll have someone who has more say in what you spend your money on...

Sorry for the sermon... just trying to offer some advice.

I dropped my motor off at the engine builder earlier today and he said all I would need are a stock crank, h beam forged Scat rods and some forged Speed Pro pistons. That seems like by far the most cost effective choice.

The current cam is by no means too big for a 350 or 355 it was Lloyd speced it out specifically for my setup. 6500 is nothing crazy to spin a 355 out to and I honestly expect to be able to hit or come close to 400rwhp with just a 355 running 11.5:1 compression Its been done plenty of times before.

Nitrous is never as good as Boost, and costs about the same in the end to build an engine capable of running nitrous, as it does a supercharger, or turbo charger. Yes the SC/turbo is more expensive initially, but you'll get it back in longevity of the engine, and it's always there.

It never runs out, never has bottle pressure issues, bottle heat issues, never has to be refilled... you get the idea.

If it were me, I'd build with the idea of going boost down the line instead, and have a ton more fun.

For about another $2k I can piece together an entire nitrous outlet kit with all the safety features necessary for longevity and reliability and that kit is capable of supporting up to a 200 shot. I would more realistically run about a 150 shot because the LT1 intake doesnt flow nitrous very evenly beyond that.

A comparable supercharger setup to run about the same amount of power (550ish rwhp) is closer to 5k with all the pieces necessary added in.

The aspect of not having it all the time is true but I am looking at it from a position of "how often on the street do you really feel that you need all 550rwhp rather than just say 400rwhp?" 400 is more than enough to get in trouble with for me and if I want more at the track I have the ability to spray it.

Also the reliability of a nitrous setup is equal to that of any supercharger or turbo setup. It all comes down to the tune.

It's also worth noting a centri, supercharger's power delivery is very linear, usually.

Myself I'm going Boost with both of my builds. My C4, and my 86Z28 (the Z is getting a bbc stroker to go with it.)
