To run 10's you are going to need AT LEAST 450rwhp. What kind of car, and Auto or M6? The PRC heads you refer to are not that great of a head. A good set of CNC'd 243's would be a better bet if you want to stay with a stock casting. Going to need more info for a cam recommendation. Are you going to be using any power adders? What stall if you are an auto? what else is done to the car? can you drive?

^^^ The PRC 2.5 5.3 heads are a great budget head. There are people making 450+ with those heads and a F.A.S.T intake. And timeslips are not all about rwhp numbers, a car with a good suspension will beat a car will similar horsepower or even more hp.
Look at those heads and a 228r, 233/239, Torquer 2 camshaft.
Im making over 400+rwhp with those heads and a small 226/228 camshaft, through a 3200 stalled automatic and factory Ls6 intake.

Heads are where all the power is man.. Do not skimp out on heads. That is the absolute last mod you would want to go cheap on if your trying to make power. I am telling you from personal experience.. If your the kind who does not suffer from buyers remorse then fine.. If not then do not buy a stock casting head. I DO NOT give a **** what you read on this forum, or what you are conned into. Dont get fooled by internet flow numbers either. Do yourself a favor... If you want to make REAL power buy an aftermarket casting.. Im just letting you know before you dump 2k dollars like I did.
Just remember if you buy a stock casting cnced head, go to the dyno and make 400rwhp, and still running 12s at the track remember, you heard it here first.

Go custom. I would PM Patrick G, PredatorZ, or even Shawn from VA speed. Tell them your goals and they will spec you a cam to exactly what your looking for.
In a stalled auto car with his race weight and at least a 1.4x 60' he should be able to squeak in with only the 425RWHP he is after

the car is a m6
its in a foxbody mustang.... the car may be lighter now but id say 3150 with me in it is a max
the reason i was thinking the prc heads is there are 2 guys here in town 1 has a 377ci ls1 with dart 225cc heads and custom cam and it only put down 411rwhp n high 3's torque......
another guy with stock bottom end ls1 fast intake and afr 205's just cleared 400 rwhp
both cars were on a dyno jet
keep coming with options and opinions

I have stock 243"s vinidcator cam no fly cutting car is 3400lbs M6 car run's 10.95's in the heat at 2000 foot d/a so in your car easy 10's with the same setup and my car made 455rwhp and 402rwtq with a heavy *** nine rear 4.56 gear and a 3.5 steel drive shaft. So your 3150lbs car with anything over 400hp with fly for sure

Becarefull with saying that-lol. There are 2 versions of the Vindicator. You are running the Original. I also have it but have a -4cc piston so I can run aftermarket heads. I havnt had it dyno'd or properly tuned yet. But really-a cam as big as the Vindicator needs to be checked for PTV clearance. some dont mind being tighter than what is recommended. Oh and I would also go with some 243 heads from a good hand porter.

I have the close to what you are asking about.
My list
00 Camaro SS
complete stock bottomend
PRC 2.5 5.3 heads
Torquer V2 cam
SLP air lid
Pacesetter LT w/ORY and cutout open
underdrive pulley
SS4000 yank stall in fully built 4l60E
12 bolt w/3.73 gears
FAST 92/92 ported by me
My car has gone as fast as 11.19@120.3. This is a full weight car still has the AC, rearseat,no weight removed except for the spare tire and jack. I do got some suspension work also. So yeah with your weight and the PRC 2.5 5.3 heads and a MS3 cam with the heads set up for it you should easily run 10's on motor.
