Big vs. Small I was just wondering lately all i have been hearing about is small cu LSx's riding out. I want to get some opinions about LSx stroker's. If you had a choice what size cu. LSx would you build and why? i have seriously been thinking about some around a 385cu LS1. It seem i here all about small cu motors rolling out and not many Big cu LS1's (meaning 402's and up).

Look, just because you wanna talk like you're some kind of a little iPod wearing punk wannabe rapper doesn't mean you need to talk down to me, okay? Speak English, man, and I won't have to ask that. "Running good times" is a LOT more understandable than "running out" and "rolling out". Okay, YO? LOL!

I know they SHOULD be a lot more fun to drive, regardless of track times. But how fun is a fun car when your 402 gets smoked by a 346, right?

You make a good point N4cer. it is just interesting that some of the fastest LSx's in the world are no bigger than 385ci. Just like that one Black T/A, i think his name is 1BadassLS1 it is only 385ci with a F2 on it. and has went a 7.95@172ish. I here nothing about 400ci motor's going anywhere.

LS1Firebird95,
Seeing that you only have a few posts, I will give you some advise...
If you want a mature and educated answer to a question on this board, it helps to phrase your questions and responses in the same way. While there are many members under 20 on this board, there are also a lot of 40+ individuals who are up to speed on the latest engine and drivetrain trends and could really help you. So chill the sarcasm and you'll get far on this board.
In response to the big vs. small question...it depends on whether you're talking N/A or forced induction.
N/A, displacement = torque. More cubes = more torque. More torque = more power. Basically there are two kinds of people...those with big engines and those who want them.
Forced induction is a different animal all-together. Often, a small bore will be less prone to detonation and will allow an FI motor to run more boost. Boost is the almighty equalizer. It's the reason why 3.0 liter Toyota motors can make over 1000 rwhp.

well said patrick..... so basically to sum this up-----
346-390 < 346-390 + FI (=or<) 402-455 < 402-455 + FI
all things being equal... such as the amount of FI etc.

What determines the speed of the resulting car isn't the size of engine that is used, but the size of the bankroll.
Comparing small engines to big engines to FI engines to big FI engines is more or less meaningless without considering what all that costs....and what it costs to prep the driveline and car to take the power once you start getting serious.
Basic good H/C package: $3,500, more or less.
All-out large FI engine: ten times that, more or less.
Driveline and chassis mods to suit.
Speed costs money, how fast can you afford to go?

I've been looking at a few different options. I had seen a few cheap 402 builds that were tempting but look around and you'll find they were cheap for a reason.
Now I'm debating most likely between an aluminum 347 build or an iron 370 build, either of which will be built to handle some serious amounts of spray (300+ at the minimum
). I can get a pretty stout 347 from FLP for right around $3200 or so (stock crank). That price includes Lunati rods, JE pistons, and ARP main studs. I don't want to spend much more than that at all, so I will probably be going with that unless I can get a forged 370 for a couple hundred bucks more.
I'd rather get a very high quality 347 than a medium quality 370-402. Better parts will be more reliable and can handle more power in the end.
Advantage of a 347 is that I also don't need to get the car re-tuned for N/A

i had a boosted 346 when it blew up, i chose to go NA 403, i wanted more torque as patrick stated on the tap in the low and mid range. i had the 346 @ 6psi with a P1 blower and it didnt make full power until 6k rpms and heads cam cars were running with me until 90mph. so for the street i decided to go with larger cubes and when i get more money together ill put some spray on it. as far as doing it on a budget, i think i was able to do it on a budget without cutting any corners at all, my build list has 100% new parts except the heads, i picked the dart 225's up for 1k with 1200 miles on them from a friend. That was the only used part. $10,364 installed and tuned was my final bill. ported fast 90/ported LS2 as well. i started from scratch, all i have is a corsa cat back on the car. because i was on such a budget im reusing the stock manifolds and h-pipe. so in the future when i add long tubes i should see a signficant gain.
NOW if i had oh another 7k i would have gone with the FFHP single turbo front mount T88 race kit,of course have the rear end built, low compression pistons of course, a twin disk clutch and run 8-10 psi on the street and make an easy 700whp.
the above option maybe in with in grasp next year though, we will see.

I might be doing 312ci of forced inducted furry stock LS1 bore, 4.8 crank with 6.125 rods, forged diamond pistons (maybe, might get another manufacturer), some ported LQ9 heads with some nice hefty upgrades, still deciding on turbo size, but maybe somewhere around a T76, running 15+psi

As to the real topic at hand, what is this 500CI stroker setup I hear about? It sounds wicked as hell. I forgot who makes it, but its very new I think.
