Default TSP Giant Cam, PP LS6 Heads and stock SB

I have seen on other website that larger cams like the T-Rex were used on stock head motors. I would like to know if the Giant Cam can be used with Patriot Performance Stage 2 LS6 unmilled heads, and a stock 2001 short block. Will there be issues of the valves hitting the pistons? This would be a N/A setup.

I actually talked to tsp about the very same question and they said that thie biggest cam they would recommend for a stock bottom end would be the ms4. anything bigger will be breaking alot of parts.

And you are going to have a geometry issue with your valvetrain if you are not careful. And fly-cut might begin to be necessary.

I don't know why I put geometry. Lol. I meant valve events. Depending on your heads you are going to want to double check before you bend some pushrods and eyelash some pistons. Clearances are everything when it comes down to the big cam questions.

Any advice that you get over the internet take with a grain of salt.
Except for this:

Always double check for your own peace of mind to be sure that everything will fit properly. And just because it fits doesnt neccesarily mean that it is any better. You might want to make sure that this cam is going to be the route that you are wanting to take.

The head are Patriot Stage 2 LS6 heads that have not been milled. The chamber was re-worked to 59cc without milling. This would give me a 11.3:1 CR.

And actually geometry will play an issue depending on what kind of springs you are planning on running, and if you are going to shim them.

I personally wouldn't run hydraulic with that cam in a stock cubed motor. Solid roller.
Either aftermarket pistons or flycutting would be needed.

That is actually the cam I am running in my 402.

Ok. I will go ahead and tell you now. 248/254 .629/.622 LSA 113 is a big cam and will probably not work with those heads.

I was going to say that it seemed like a stroker profile.

This cam will not work, might not even work with flycut pistons.
Besides it would be a huge waste in a stock motor unless it was 13+:1 Compression and a race only car.
Probally a trailor queen.

It is.

2300-6800 RPM Power Band with a peak around 6400rpm; This is an excellent performance camshaft with a rough idle! Custom tuning required

THIS CAMSHAFT IS DESIGNED FOR BIG CUBE ENGINES!!
That is from TSP's site.
