Best block for a 440
Best block for a 440 So i helped my brother buy a new house and since im a first time buyer i get an $8000 bonus on my taxes this year plus the money i usually get about $2000 or more so come apirl ill have $10000 to play with and i was thinkin bout a 440 for my 02 ws6 im just not sure what the best block to use is. i was thinkin a lsx or ls7 the warhawk and rhs blocks are way to much if i do this motor i was hoping for around 550rwhp on pump gas and a little n20 maybe 150 to 200 shot so what would the best block be to use i would rather not spend more then $2200 on a block. Also i was thinking trickflow 235 heads ported fast 92/92 and a custom cam prob in the 240 range. Thanks for your input.
The long block with TFS 235's would be in the $10950 range using better quality valvetrain components or $10389 using LS7 lifters and Comp Magnum or TFS PR's. Add 1100-1300 for a ported FAST combo.
For real heavy nitrous use we would rather see a 4.155 bore and 4 " stroke (434 cid) but as is it will handle a good amount. Tunning is the key as gasket material gets thin between cylinders.
Lead time of course depends on availability of parts but the piston alone will take in the 8 -10 week range to have made. Its not a quick build.
But we do have a 454 right now that a customer can not complete. We could use that engine I supposed and order a different crank to make the 440 and build time would be greatly reduced. That leaves me with a 4.125 crank but we can use it in the next 454.
TFS 235's add $100 for the 6 bolt option, add $350 for 6 bolt 245's.

I've been looking to upgrade to bigger CI and go NA but i want to know what's the biggest CI we can go on an LS7 as far as the stroke goes without having premature wear on the block? I've heard of people who have problems when they go with too long of a stroke. Is there any aftermarket blocks where we can get 500+ci?

You would have to re-do the pistons as well.
BTW, I saw your motor yesterday
your right, forgot about that. Just would not be a good idea I suppose. We'd need to start from scratch.A saquatch sighting?!@?!? LOL j/k.
I'm making the car ready for it right now. If I get all the bugs worked out in time I'll take it to Texas here in a few weeks. I've got a road trip to Wolfforth (TSP) and then maybe Houston planned

Yes to 500 cid. The superdeck blocks from ERL would be what your looking for. We build them the ERL SD as well but your looking at decent money for the block.

Now, is that necessary to achieve your 550 RWHP? Nope. You can do a motor for ALOT cheaper and make 550 RWHP than a 500" version. Now, don't get me wrong the 500" is a BAD BOY
but ain't gonna be cheap!If you stay in the 400-450 range, you can get there (550 RWHP) and will be cheaper than the 500" motor. Now granted, teh 500", all things being equal (except $$$$) is gonna make more power, and make it easier.
All comes down to whatcha want to spend, and what kind of deal you want. You could do a 434" LSx Block with a 4.00 crank, good heads Like AFR or TFS or All Pro (that's what I like, but more money though) and go make power. Man, there is a million different combo's, but YES, you can do it though is the short answer!
don't forget before you even start down this road make sure your drivetrain can handle all of that added power. No need in spending your whole wad on a motor just to have the trans or rearend go out.
So i helped my brother buy a new house and since im a first time buyer i get an $8000 bonus on my taxes this year plus the money i usually get about $2000 or more so come apirl ill have $10000 to play with and i was thinkin bout a 440 for my 02 ws6 im just not sure what the best block to use is. i was thinkin a lsx or ls7 the warhawk and rhs blocks are way to much if i do this motor i was hoping for around 550rwhp on pump gas and a little n20 maybe 150 to 200 shot so what would the best block be to use i would rather not spend more then $2200 on a block. Also i was thinking trickflow 235 heads ported fast 92/92 and a custom cam prob in the 240 range. Thanks for your input.
Plus, you can rebuild it a bunch of times if need be through the years. Should be the last block you ever own.
But the complete engine plus the nitrous system, upgraded fuel system, dyno tuning and install. Only $10,000 won't do it.

Hmm i was pricing up stuff and ill prob need more $$ but im just lookin into different builds i can do havent made up my mind yet. A 500" motor would be awsome i saw in gmhtp they did a 496 with a warhawk tall deck block and i heard the new rhs tall deck block can get 500" i bet both of those would be cheaper then the erl superdeck but still a bit out of my range dam! basically what i would like to have is 550rwhp to 600rwhp on pump gas that i could drive on the street like weekends and when its nice and also handle some nitrious so maybe a 434lsx doesnt sound to bad!
I want to try the LS7 440 built for NA with standard tension rings and high compression. I want to stay away from nitrous and my goal is to hit a 10.5 on motor. I have some TF 235 heads and the FAST im just shopping for the bigger motor. I want the LS7 cause weight is a concern. Im putting this in a truck.

erik built my last few motors just looking into building another one but for my gto and tired of the iron 408 in it. i will let it rumble around in my head a little longer and might order one from ccperformance since built by erik

So as Gen414 said there are many combinations to hit 550 rwhp. I would not drop the coin for a tall deck unless 650+700 rwhp n/a was your goal or you were looking for max cubes and power add.
We've got a 457 long block that will run mid to low 9's in a 3300 lb car on 91 octane pump gas n/a for $15950 or a 460 you can spray up to a 200 shot on for $16750. 457 is an LS7 and the 460 is a re-sleeved LS2. But those are way beyond 550 rwhp
We can do a nice 408 long block for you for about 8k and get you in the 550 range, you can spray a 250 shot on it or we can add some different rings and build it to take 300+Or we could do a 416 and keep you in aluminum for about $9200. Have you around the 550 range and the ability to spray as well. So there are a few options and you certainly don't have to break the bank to hit the power levels your looking for.
You could get 550 out of a 408 cid on up so it really comes down to budget. The bigger the engine the easier it makes the power (with the right heads of course) but 550 isn't a huge number. Erik and I were talking last night about a couple 408's he did recently with TFS 235's on top putting down 550 through stout drive-train.
