Why do people do 383 Stoker LS1 I've been watching some videos on YouTube thinking of ideas for my 2000 Z28 Camaro and I saw that the dyno videos of 383 stroker builds don't make that much more power than a big cam,heads,Intake, stock internals LS1 so why do people do the 383 stroker kits in the first place
Reason for 383 LS?
Back in the early days (1997-2003) people built 383 LS1's with heads cam and spray to beat folks that had heads & cam 346 LS1's with spray. Forced induction was rare and tuning was much cruder. Any edge was an edge etc.
Now the extra 35 to 50 foot pounds of rear wheel torque NA is a lot of fun in a daily driver type car/truck. With the same heads & cam, intake package the LS stroker will make the power lower in the rpm range etc. The extra ~5 whp or so isn't impressive. In short one can have a very docile nice driving 383 LS vs a more high strung 346 LS etc.with basically the same peak hp etc.
The well mannered daily is main reason I have a 383 LS1 in my 91 RS. The car drives basically like a stock LS1 and can pull 6th gear at 35 mpg if one wants...and makes 465whp. Its a fun driving set up but definitely not the hot race set up.

Why do people only look at peak horse power numbers?
Why do people spend 15g on a big inch motor to make 700 wheel when they can throw a procharged on in a weekend and make that power for way less $$$?
Simple answer we all have different goals and power under the curve matters.

Increase in torque!!! Thanks Reason for 383 LS?

Torque in the mid-range driving RPM. Not a dyno Queen!!!
Biebs is right. More midrange torque, in the useable rpm range.
The 383 will have some hp advantages but the midrange will be better than stock cubes.
It will feel better & funner just cruising around as well. You don't have to be in high rpm to feel the strength of a 383 compared to stock cubes.

If there is one thing I can support without thinking twice is more cubes. More torque and more horsepower go a long way in your quest to be quicker and more cubic inches is a good way to get there.

I did one because it was the most practical way to go since my block wasn't hurt. It would have cost me more to go to a LS2 based stroker. I'm happy with the power it made (467 through an LS6 intake and a 9" with 4.30s). I think cost is the biggest factor for most of us.
that’s bull s#@t, 383s built and tuned right make excellent power. I built One 4 years ago using hand ported Dart 225s, a 243-251 .624 cam with a Edelbrock ProFlo that made 534rwhp through a 3” X’ed exhaust system dumped on 91 octane, not too many 5.7 making that number NA, Tusky......

I'm not a fan of dynos as they all read differently from one another. Remember Pat G also cracked 500 rwhp years ago out of a ls1 stock cube motor.

Im thinking in my mind with a 400 pound weight reduction the h/c/I ls1 car will trap 127 mph ..

It's all about airflow. Topping off a 383 with an ls6 topend will obviousley be lousy compared to a high dollar 346 build. Put a good set of heads and a decent intake on a 383 and it will walk the 346 all day long.

Now I'm not crying just stating facts because I actually don't have too bad of air where I run and some guys are running in 7000+ DA. So lets not act like you have it so bad down south especially with some of those fly paper tracks you can't walk on without losing a shoe...LOL

97 Kpa was ambient pressure. Since moving east, it is 101 ambient in SC. DA on a bad day here might reach 2k. Phoenix was 4600-5500.

Since you like facts elevation plays a big role as well as temp in calculating density altitude. If it's 105 degrees in Miss. with 99% humidity the density altitude will be similar to what it is here at 90 degrees so it's very likely you could have the exact same DA on the same day in Miss. as I do in Iowa. Now the hotter temps on a sunny day will play a factor in track temp, but since we are talking about trap speed it's all about air density. The southern states also have the opportunity to run in much lower DA after the tracks up here close due to colder temps. We don't have it bad here at all compared to some other states, but lets not act like the south has it so bad. Of course August isn't good for anyone's record attempts, but there are some days in the spring and fall down there where you will see better air than just about anyone in the country. Then lets not forget not all tracks are prepped the same. Some of us are still fighting traction on the back half of an 1/8th mile around here at podunk tracks that are worse than some no prep tracks...

Go to your Google bar and type in worst summers in the United States. Mississippi is #1.... California is not even in the top 10. I know in the day time it gets hot in California but at night it cools off with that good dense air floating around. Mississippi is different. 10 at night its still Muggy as hell. You'll catch a break here in early October but the tracks will be on the borderline closing for the year. I cant speak on Iowa.
