Default Swapping in a 96 LT1 into my thirdgen, cam selection help

Hey guys, figured I would ask the guys in the "know".

i was originally just going to swap in the stock engine, but since its on the stand right now i just cant help but upgrade a few things.

Engine: 96 LT1 had 70k miles on it, all stock
just got done changing all the gaskets: head gaskets, rear main, oil pan, intake, ect.

I was looking at the LT4 hot cam, yeah yeah i know, better cams out there, but what?

the car has a t56, and will primarily bed used on the street, and some canyon driving. not into dragging.

already thought about 1.5 or 1.6 roller rockers, need help on cam selection thats not a donkey dong, or a drag cam.. just something with better power and hopefully not expensive.

I also have a brand new set of LS6 behive yellow springs from an LSx project that i never used... can these be used on the LT1?

exhaust will be hedman 1 5/8" shorties with 3" collectors to dual 2 1/2" out to a single 3" dynomax system.

thanks, any help is appreciated.

+1 on the cc503

why not run a long tube? better sound, more power, easier plug access, etc.

I think you'll like the 503
Don't forget springs, NSA roller rockers, guides, hardened pushrods.
I'm not a fan of beehives, but some people like them. Patriot Gold Extreme are the way to go IMHO.
You'll also need a tune, intake manifold gasket set and timing cover gasket set.
Don't forget to check the timing chain while you're in there.

Already have the shorties, plus my thirdgen is waaaaay low.
Already have all the gaskets, and planning on the tune, not sure who to use for tuning though, suggestions?

Yeah I was eyeing that 503 cam, just might go that way.

NSA rockers? Why NSA? I thought we had to use SA rockers? What keeps the tip from not slipping off?

Patriot gold extremes I thought were good to .620 lift, isn't that over springing for this cam?

Thanks for all the help

NSA rockers use guideplates (purchased separately) located under the rocker studs to keep the pushrod centered. They are more stable in the higher RPMs than SA rockers, and IMO are cheap insurance. Keep in mind you'll also need hardened pushrods, but I'll assume you were planning on replacing them anyway.

for what your looking to do out of the car id say stick to the lt4 hotcam. cc503 is a very good cam with lots of power and its on the edge in my opinion on daily driver/drag cam. by all means its a good driver but my instinct is telling me you will be happy with the hotcam. the lt4 hotcam will not require use of guide plates or nsa rockers. the cc503 aggressive lobes will benifit running nsa and guide plates on it. you will be fine using a 3/8 stud/rocker set up and the hotcam doesnt need to really agressive springs. i think its max lift is at .525 or something on a 1.6 rocker.

FWIW I ran my cc503 setup with SA rockers and stock studs with zero problems

Cam installs are a gateway drug.
Today, you'll want a hotcam; tomorrow you'll wish you'd done 503 and before
long you'll have hogged out heads and the back seats will be in the shed.

The reason I suggest those parts is that they will last and they will support your future mods.
If you run a hotcam, you can probably get away with SA rockers for now.

As for the tune, Ed Wright (fastchip.com) has done most of my tuning for the last 12 years.
He's expensive, but he does a very good job. You can request a mailorder
tune from his website and be confident that it will work. MadZ28 is another
option, Ion does a great job on bolt-on and h/c tunes. He's a little cheaper too.

oh im sure, i wasnt saying you couldnt. alot of people do run guide plates and nsa rockers with the comp xe (extreme energy) lobe profile cams. im on the same boat with you, i dont usually run guide plates or nsa rockers unless im going with a set up im going to spin really high. for a daily driver cammed car (canyon carver) as the op put it, he'll be fine with a sa set up running a small cam no need for him to go with a nsa set up.

IMO, there's no need NOT to go to a NSA setup. They are more reliable and lighter than SA rockers, not to mention the additional RPM support. And once you go with a NSA rocker setup you don't ever have to change the rockers if you eventually choose to go to something more aggressive. I ran NSAs when I was cam-only, and am now using the same guideplates and rockers on my 383. You get all of this only for the added cost of guideplates - about as much as a tank of gas.

If you are thinking of going the hot cam route also look at the cc305.

I would go with the hot cam kid and long tube headers.

If you get a GOOD tune, it will make that 3rd gen move pretty good.

Making the numbers below with the hotcam, slp midlength headers, pcmforless tuning. The little cam can make some decent power. I plan to go bigger with it soon but it's worked well for me for the last 6 years.
