3K for a sixer, unless it's beat to hell, or owned by a grandmaw there is just no way you're gonna get anything newer than a 98 maybe 97 with 3K. The old 5.0s are a toss up because with what I have listed you could technically buy one for around 3K and be fairly fine as everything engine wise is being replaced and then the tranny, of course, would be next, which is something he forgot about. In any since, the argument is 100% pointless.

+1, pointless arguement. It is cheaper to work with what you have already, whether it be a 5.0, 3.8, 4.6, whatever. Its cheaper to work with what is in there rather then to buy something new, trade for a new car, or swap an engine.

--UNLESS you find heck of a deal to make it worth the trade.

There are a lot of comments beign pushed intot his that aren't valid to the discussion.

5.0L fox V8 cheap ...sure of course. We're not talking fox cars.
SN95 5.0L - come with the same hp/tq as the 4.2L V6 .....ooops... where's the big bad V8?

Let's take that $5910 to get 550 hp number though. It's legit. (Not talking car price or labor since we're assuming we do our own work, just mods)

Let's go high end SClong block$500. 4.2L crank $100 at any junk yard. Home ported heads and lower intake - free. Bigger cam we'll call $350 to be fair. M112 $500 (high end again to be fair). Modified to fit the V6free at home. Boxed upper we'll call $400. MAF, injectors can be picked up for $300 used. Fuel pumps are $250. Full exhuast will run you $400. Clutch that will take the power level will be $400. Tune will be $500.

over 500 for $3700 on a V6.

But there is more budget to play with. I picked up my KB twin screw for $800 used. Replace the smaller injectors with upgrades so add another $200 to their original price for larger units. Larger fuel rail and line will be $300.

So we're sitting at $5000 and flirting with 700hp/tq.
