Cam advise
Hey guys I have a Pontiac G8 I know it's not a Camaro but very similar engine. I was looking into a mild cam with some head work. But I ended up picking up a set of aftermarket heads locally. They are milled .030. I have a 3200 rpm circle d converter, with 3.27 gear. I was looking to change the gear to a 3.73 but I everyone I hear says stay from Richmond gear and I'm not sure about another company so I have been looking at 3.91 from GM. I have a GPI ported and rod mod LS3 intake and throttle body.
I would like a bigger cam than originally thought to support the heads. I have called around and off course get many different answers. GPI recommended SS3 233/253 .646/.637 112+4 lift seems pretty high Cam Motion recommended Titan 3 227/237 .621/.604 LSA 113+3.5 or I might give up little off the line of I don't go higher stall but they said their Titan King would be a great choice as well 232/244 .621/.604 LSA 112.5+4 Tick performance torque master 1 219/230 .607/.573 111+4 Texas Speed Cletus McFarland Bald Eagle cam 229/242 are all they really tell you Just trying to see what the thoughts from you guys would be? Here is the info on the heads

Out of all those I would go with the GPI hands down. The tuner I use loves the GPI cams.

What are your goals and is this a daily driver?
Out of those I would run any of those except the ss3. The SS3 needs a bigger stall than that 3200 circle D. I have the same stall and it is not an optimum stall speed for the ss3. You can probably get away with the SS2 from GPI but 3200 is basically minimum for the ss2. GPI has the best cam specs imo for all out power. There cams are proven but that doesn't mean that is what you want. If you want little or no maintenance and the springs to last over 50k I would try to stay at or around 600 lift. Also, Cam motion has amazing cams and GPI cams are ground by Cam motion if I am not mistaken to GPI specs. Remember you have a 6.0 so it is a little smaller then the LS3 6.2. They are close in size but you can get away with a slightly larger cam in a 6.2 than a 6.0 as a daily. If you go to the G8 forums a lot of those guys run cams in the 216-226 intake and 224-230 exhaust. I personally would run a Cam motion Titan 2 222 230 595 587 from cam motion or an ss1 or ss2 from GPI for all out power with your stall and gears. Make no mistake the Titan 2 lopes hard for a 6.0. You will know it is cammed! The worst thing you can do is over cam a street car. Guys do it all the time and you see them doing another cam swap down the road. Go to the G8 forums and check out what those guys are saying as well. The difference between the ss2(very similar to Titan 3) and ss3 is probably 15hp or so and your drivability won't be great with that cam imo with that 3200 stall. Follow what the manufacturers of these cams say or put in a bigger stall but 15hp isn't much when it comes down to it and bigger cams don't make funnier street cars in my experience unless properly set up for it. |

Go about 9 minutes in on the Video. Titan 2 is a common cam in these cars.

Thanks guys. Spoke with Steven today and he suggested the Titan 3 and for all out power the Titan King. Spoke with the shop that I got the heads from and they stated a can 23X/24X is their recommendation.

Contact Rick Crawford. And check out the G8 forum. Loved my G8 when I had it.

Agree that the SS3 is a bit much for a 3200rpm stall. You gotta keep piston to valve clearance in mind too - with .030" milled, you're gonna be flycutting with any of our cams.
Yet another thing to consider is the L76 is a bit of an odd duck - you've got the big valve 823 heads on the smaller 4.000" bore. This shrouds the intake valve quite a bit, so you need to be careful with the intake duration. You've got the compression to make something like the SS3 work with flycutting and the right converter...

Do you think I would I need to flycut with aftermarket 11 degree heads?

If you know what the intake and exhaust valve free drop values are for those heads (before, or after the milling) as well as what your piston deck height is and the depth of any valve reliefs (depends on which motor you have, but probably .006 out of the hole and flat top pistons) then you can have a pretty good idea if you're going to have PTVC clearance issues or not. OEM LS3 heads have around .135" intake free drop, and .160" exhaust free drop. At that amount, with stock thickness .051" head gaskets, you're at acceptable but minimum piston to valve clearance.

Cam Motion recommended Titan 3 227/237 .621/.604 LSA 113+3.5 , maybe grind it on a 111 or 112 lsa
