That is possible, but it sounds like you have no experience with boost. I would take a 600 hp PD blower truck any day over the 600 hp NA build that you are talking about. My opinion is based on my experiences.

 

Think about it like this

What is easier: adding boost later or pulling your whole turbo set up off then redoing the whole engine to get more cubes? Or even pulling the whole engine to harden your stuff before you hit me with the “jUst tUrN UP tHe BoOsT”

 

I think that you are saying he should build the motor. But if he builds a 12:1 motor, adding boost later is not a good idea. Your post is confusing.

 

boosting a 6.0 is cheaper and will make more power per dollar spent while being more dependable. The 408 platform by itself is less dependable than a stock stroked motor. The 408 motors I run are on weekend warriors that don't see a ton of miles and can spend months down for rebuilds. By the time you purchase the rotating assy, buy heads and an intake that will flow enough for a stroker motor and pay for machine work you could have slapped a bolt on source of boost onto a stock 6.0 and made more power.

 

How is it confusing?

Okay Timmy do you want to add boost onto your big cube motor after you build it OR pull all your boost stuff off then pull your motor out to add more cubes/reinforce? Which sounds like more work?

Now yes I understand adding boost to a high comp motor is not a good idea. That is why we have meth injection to alleviate some of the bad that comes with high comp and boost. Then even so a head swap to drop compression to add boost is much easier than disassembling your whole setup to pull the motor to then bore it yada yada yada.

P.S. You absolutely can run boost safely (with meth injection) on an 11 CR motor so my argument still stands that it is easier to add boost AFTER you have built the motor to your liking.

 

He can enjoy the fact that he spent less money and still won. a $100 pulley can make him faster and he can still retain factory like drivability.

 

This is true! Absolutely right. It is for certain something OP needs to think about, does the durability of the 402 matter? In my opinion probably not. Most stroked motors from what I have seen, mind you YMMY and this is not a first hand experience, last about 50k-60k miles before they need to get relieved of duty. Most of our setups probably don't last 50k-60k miles before we decide we want to change something or new information comes out about XYZ. Edit here: I think that really if the motor is built right and not just LS Tweaker garbage then it will last longer than you own the truck.

It all depends on the OPs wants. If he wants to do the 402 no problem. I would agree with you that yes it would be much faster and easier to do boost. I'm going to restate my original thought here and say OP should just build the motor. If he decides he wants to boost it later on then it will be easier to add boost after the fact. OP should do what OP wants to do.

 

a blower is basically like swapping an intake manifold. It's not much work at all. 98% of stroker motors will get gapped by a stock bottom end 6.0 with the right cam, boost and tuned properly.

 

I was thinking more in terms of a turbo. Why go blower when you can go turbo for half the price and make more power lol
I agree with you yes though it is not much work for a blower, I guess in that way my argument is a little weaker since that is a lot easier.

Still is a pain in the *** if you needed to swap pistons/rods/crank rather than already have that **** done and you can just pile on the boost.

 

I guess our definitions of a ton of work is different. it's just nuts and bolts. odds are, once he sees how much power the 6.0 can make with a turbo he'll probably not be able to justify the expense of a 408 anymore.
