Default Help me nail down a combo

Ok,

I have a G8 GT and im trying to nail down the combo i want to put on the car so i can get parts ordered and get it going. My goals for the car are as follows:

-450whp + (no more than 485-500)
-Maintain decent street manners
-Maintain at least semi decent fuel mileage(obviously gonna loose some)
-Dont want cam profiles etc that are gonna kill valvetrain parts.
-Basically want it to run like it should have from GM lol, and last a
good while. Its a driver not a track car.

The budget is approx 6k installed and tuned. (if possible)

Any advice i could gather i would much appreciate.

Your best bet is going to be a used blower kit.

i think this power can be made on motor pretty easily. id not even consider leaving the stock cam in this car. its only a matter of time with those afm lifters.

You've probably heard it before but the l92 head and a good cam with a great intake will net you those numbers. Or you can go with a blower but you better have better internals if you go over 500 hp. You can stroke it out to a 408. You can get a rotating assembly pretty cheap these days but I would balance it all. So many different ways to do it but it all depends on what you want and who's building it.

He has a G8 so he already has a rectangular port head from the factory. There are plenty of cars hitting 500 hp with stock internals. Patrick G is one of them, as a matter of fact he has 508 rwhp. The OP's budget is 6 grand. You are not going to build a stroker for 6 grand.

yea im not seeing where its neccessary to build a stroker to come close to those power levels. id stretch the budget a good bit if needed, but honestly i dont know that its needed. I really dont want to put boost on a stock bottom end at all.

Possible Combo:
Mast LS3-Med Bore 12-degree black label heads
Fast 102
Stock ported TB
Roto-fab
Kooks LT, Off-Road X, and Solo Axle-Back
Cam?????
Tuned(Probably be done by Mike Norris)

Thats sorta the high buck version the other one is
Dr J Airwolf LS3 heads(pro comp castings)
Ported LS3 intake
Stock Ported TB
Roto-fab
Kooks LT, Off-Road X, and Solo Axle-Back
Cam???
Tuned(Probably be done by Mike Norris)

With either setup probably going to run a 3200 stall yank or precision or should i look at a different speed? or manufacture?

They dont have the triple disc stalls really lined out do they?

smallish cam and aftermarket heads are a bit of a waste for your HP goal.

Have WCCH port your stock heads
102/102
4" CAI and MAF
FTI cam 234/240 112 range.
Manton 11/32 .125 or next size down push rods
Lunati gold spring kit
4" exh or cutout
