Default Displacement= expensive?

Forgive my ignorance, but why does it get so freaking expensive so fast when you start to look at higher displacement motors? I have a stock '00 Ws6 and if I end up taking the motor out to bulletproof it soon I figure, "why not raise the displacement?" I want a 427 or a 454 if I'm going to do it, and I understand the sleeving process is expensive, but what the hell? I can't find anywhere that will build even just the block and rotating assembly for less then 8-9 grand! That's nuts! It's just a fun car, not a full-on race car!

If anybody knows a less expensive way to get big cubes, please let me know!

Thanks!

Even if you were trying to bump up a Gen I or II small block to that kind of displacement, you would be talking about lotsa money too. All of the rotating assembly parts and the resleeving and machining are race grade parts for this kind of project.

If you mainly want more torque and HP, consider a supercharger and a bigger cam. Even there, you talking about 4 to 6 thousand.

That's why you see alot of 402 and 408 strokers. They put out killer power and are much more reasonable to build. But they still cost big bucks when you add all of the supporting parts like drivetrain, fuel system and suspension.

Yea, it does get expesive but the more cubes you got, the better base you have to build on. You should be able to get a forged bottom end and machine work done for less than 8-9 grand though, that seems high to me. I was looking at forging my bottom end but after some research found it's cheaper to buy a 402 or 408 w/ a forged bottom. They are nice for more cubes and stronger than stock. Resleeving does start to get expensive but you really start to get expensive, like DrkPhx said, when you start putting on supporting mods for major power like complete fuel systems, full suspension jobs, full powertrain (new tranny, new rear-end), etc.

I miss this too. TSP, SLP etc. 402- 408 with LS2 block 4200 roughly. Sleeves and labor to do a resleeve (sleeves 900), Labor (1000) so say if you had an LS2 block already 2000 to get it sleeved. The parts cost the same in a 402 as does a 427 (pistons, rods, crank), 4200+2000= 6200 I missing it too, I have been in the buisness long enough to know that people are being taken advantage of when building a 427.

Depending on who is doing your work, the sleeving will cost you more than that. My LS2 dry sleeve was $2500 + $300 for a longer sleeve for the added stroke I am running. So there is almost $3k by it's self. As for your equation above, You need to take into effect the cost of the stock block in the $4200 price. You need to remove $1k from the price giving you $3200, then add in your sleeved block price of $2500. Now you have $5700. There are plenty of sponsors on here that will build you a motor for a reasonable price. You do have to remember that they need to make money to, so they can stay in buiosness. The sleeving of th eLSX block is more involved then most think. To do it right, you need a "wet" CNC machine, a skilled operator, and a place were you can keep a constant room temperature, so your metal stays consistant during the time that you are sleeving, which has to be done all at once, to be done correctlly.

Sometimes it seems like going turbo would even be cheaper than going for bigger cubes. Not to mention that you have greater power potential with a turbo. When cost comes into play, I think there is a replacement for displacement.
