Unless you are planning to run a blower/turbo or adding a 150-200 hit of NOS, you are not going to see a "livable" (i.e. streetable) 600HP 408. JMHO.

A good place to star would be going out to 427 cubes. I know that can be done.

Keith Craft advertises a 427 Windsor that produces 580 HP for $11,495. I'm sure this maybe slightly conservative, in order to match this number on a regular basis, but it can be tweaked upwards too.

There are other engine builders out there, so I'm sure this could be duplicated by others.

Find an outlet for a used Nextel Cup engine. It'll have all the good parts and be "Way North" of 600HP even after you detune it. 358 CU IN

600hp can be achieved with CHI 225 heads and manifold using a cam something like this 242/248@ 0.50 duration 630 lift 106 lca. These results can be seen on the engine masters challege for the last 3 or 4 years. These are Cleveland style heads though not windsor heads. Makes a big difference.Check out these engines from MME and Kaase

OR, you could just buy one for lots of $$$$. RDI does a 427 stroker (all aluminum 635 HP with a solid roller cam.

How much money do you have to spend?

I did 600 easy hp with 445ci and a small hydraulic roller camshaft.

You can also do a 408, use the 225cc AFR heads, a Super Victor intake, and a solid roller camshaft.

Decide how much money you need to spend, and I can help you pick a cam.

Keep in mind though, a 600hp 408 won't be too timid...

600 hp will be easier to get on some dyno's as compared to others.

On pump gas right?

Whew!, it will take more than a set of heads on a 351W.

I think Red is right, get a power adder.

Can I ask, why is 600 hp important?

Besides, everyone knows that 1,000 hp is the new 500 hp

Go with a big block instead, the low end torque will be much more fun than the high rev. horse power.

Coach bought a 408 from Keith for less than $10K and got something like 525 fwhp & 535 ftq. Coach installed the motor in his Daytona Coupe. Very streetable.

You don't need 600 hp in every car.

A 427 bore/stroker combo would be a good place to begin. I would agree that with other on this thread that would say that breaking the 600 hp barrier with a streetable combination would be almost impossible without some sort of power adder. Suggest you take a look at a centrifical supercharger. This combination on a 351-w based stroker should get you into the 625 hp (600+ ft-lbs torque) range on 93 octane pump gas in a streetable combination that should last for awhile.

Yes it can be done, however; it is not that easy to do if it is a street engine on pump gas with a hyd. cam. Anybody can advertise 600 hp on a dyno, but is it an honest 600hp? Remember horsepower is a marketing tool (It sales engines).

You will need a dart block, big heads that will flow at least 300 and an intake that will flow just as good (225cc and super victor intake) and a big cam and a lot of stroke

My engine specs
461Ci SBF
AFR 225 heads (8mm valve stems with titanium retainers)
High rev lifters
LSM custom ground Hyd. roller cam 262 268 at 50, 680 680 with a 1.72 ratio
Super Victor
Ross custom pistons with total seal rings (gapless)
Eagle rods and crank
Quick Fuel 850
Max dyno pull 601 HP 596TQ (small headers)
Average dyno pull 596HP

Give Adam or Mark a call http://www.precisionraceengines.com/ they did a great job for me.

I have this engine in my coupe and it dyno'd at 579.5 HP, but 609 on torque. Torque is what really counts!

Thats the one Rick, Keith Craft built me an alloy engine based on 351 windsor 9.2 deck, based on Cup parts and new parts, this engine produces "Way North" of 600hp with 373 cubes, 10.3 comp ratio, so can run pump gas. Usage is mainly club racing and some road use to enjoy the capital outlay, but this aint a town car with Jerico etc! I strongly recommend KC everything he promised I received and more, plus I am hard to please, we dynoed the engine here as well to test a different inlet manifold and were pleased with results.

My WIndsor based, 600 HP motor built by Keith Craft, is cery streetable. A buddy's, only displacing 410 ci, is at 590+, and is just as streetable. Both use AFR 205's that Keith has worked his magic on. I'd say it is definately doable without a power adder!

Talk to Keith!
