If all you want is 470rwhp, I wouldn't buy a sleeved shortblock. That's very expensive for very limited returns.

HCI @ 470 isn't going to drive like stock. And takes a lot of attention to detail.

I think the best NA goal is to get a 6L truck block and throw a 408 stroker kit in it or goto someone like Thompson and get a nice shortblock for a good price. Then add something like the PRC 247 heads to it and a good mild cam and make 500/500 with good streetability. Getting to 600+ NA needs LS7 heads and larger bores (resleeved or LS7 blocks--costly). But the cost isn't really worth an extra 25-50HP. It's a very diminished return. And guess what? A 408 with like a 239/247 cam will run mid 10s @ 130 all day in a full weight car.

But, a Turbo @ 470 is very low boost and very much stock like drivability. Cheapest way forward is with a Huron kit deal. If the car is mostly stock, stick a mild turbo cam, valve springs, and a 7875 VS turbo with Siemens 60lbs injectors and a Walbro 255 fuel pump kit. You can do 500/500 with that (actually you can push to 700/700 if your fuel system is upgraded enough) and it'll last a long time and be very fun. Shouldn't overheat if you get everything ceramic coated and wrapped.

Other option is a P1SC Supercharger kit. Little more money but can do 550-600rwhp with a mild blower cam.

I think what you need to do is set a budget then figure out what gets you there (500rwhp, $5k budget, stock drivability, longevity, etc). Then do an AoA against all the options (what we do in engineering trade studies - set your evaluation criteria and your weighting and score it). I bet an NA Superstroker with stock heads comes in pretty low during that comparison.

I was just using that as a comparison for what I think a Best-of-the-Best H/C/I/V package would get me.

Stock heads is just for now. My end goal is to have an "NA Superstroker" (had to use that!) with a mild cam....equivalent to an LS1 with a 224/224 or maybe 228/228 cam, and LS3 or LS7 heads. An "NA Superstroker" has always been my end goal. I was just thinking of doing the max H/C/I/V for now, then getting the Darton sleeved shortblock down the road, then going from there. But that was before I put the list of parts for the H/C/I/V together.

I really don't want to go Turbo or SC. The engine bay is already tight. I don't want to add more stuff.

Perfect....more cubes to choke and more money to spend. You need to research more. Blower doesn't take up all the engine bay space and will give you plenty of power.

I missed the 470hp part lol that is too easy to obtain and no fancy parts needed. My ported head and cammed LS3 made more then that on a mustang dyno. All this talk about 440ci, 454ci and stuff I figured the goal was well over 600whp.

The 470HP is just what I figured a Best of the Best H/C/I/V package would get me. It was just a reference. I am sure a 454 with LS1 heads and a mild cam will be more than that and even more torque. I cannot afford a short block and H/C/I so it is either 454 short block or top shelf H/C/I/V. The only options will be
- 454 with current LS1 heads, current valvetrain, current LSX 90 intake, current 102mm TB
OR
- Current stock LS1 shortblock with top shelf heads, custom cam, lifters, pushrods, roller rockers, port matched LSXR 102,

I say add another option... sell the LS1 to fund new engine. I tell people that all the time looking to go faster NA. They want to pay for parts and labor for a DoD Delete, cam swap , valvetrain, etc.. I'm like sell your entire engine and use the money you were going to spend on mods for a new larger engine that actually works. Guys easily get $1500+ for aluminum short blocks, and they were going to drop an easy $2000+ modifying it. Now you have at least $3,500+ towards your goal to do it right the first time. You can almost always find a 416 or 427 shortblock under $5000, throw some LS3 heads on it and be well well above your goal for not that much money. Or you can buy a $500 5.3 and a $400 Chinese turbo and make double your goal, either way its exceeded for minimal budget.

Personally I had an LSX454, neat but don't think I would go that route again. You can make damn near as much power with a 416 or 427, rev faster, etc and be cheaper.

I am not looking for minimal budget. I am looking for long lifetime. Thus the Darton sleeves instead of an LSX. I'm not buying a used motor either.
There is no way in hell that I will get $1500 for a used 1999 LS1 shortblock. Hawks sells LS1 longblocks for $1300.
I will not purchase a stock LS block with a stroke over 4". Maybe an LS2 shortblock is under $5K, but I don't think you will find anything bigger, unless it is from "Jim-Bob's Moters n Fishin"

454? LS7 heads, even stock.

Sell all your cathedral **** and grab some used stock LS7 heads, LS7 intake and a 92mm TB just to get you going.

that is exactly what I am considering right now. I just don't think I will be able to afford stock heads, and LSXR 102.

Grab a sniper for like $500. You will be close enough and running while you save up for the ITB you know you want.

FWIW I seen shafiroff racing in NY has sleeved ls454 short block $6k

Edit -- LS next not sleeved.

JakeFusion

LS Next/SHP is a better block.

Now I have to go look at Shafiroff again. Their prices are very good. And their quality is excellent. And their prices include freight.

Doesn't the LS Next have Gray iron sleeves? Aren't the sleeves stock LS length?

FCar2000TA

iTrader: (7)

What about the LSR block? I think that has Ductile iron sleeves. Anyone know the length of those sleeves. That would be around $1500 more than the Darton sleeved LS at Texas Speed, so I probably can't swing it, but might be an option.

Again, stop asking for input if you aren't actually open to the input from people who've already gone down the road and have real world experience.

So what do you know that ALL the people here who have actually "been there AND done that" somehow missed? Is your situation somehow unique enough that you need to spend way more than necessary to do what many others have done for a lot less??

Under $5k? When did you buy it 2008?

Their site lists a 416 at $8k now. Apparently, it's assembled by Thor or something.
