What are the approximate hp numbers i can get out of a stock WS6
by cranking the LS1 to 383?

will prolly add longtubes and exhaust but that will be later

 

769whp and 802ftq

 

Whoa whoa whoa
you have to be kidding
there no way its gonna jump from 325-769
i was thinking maybe 400-430

 

 

haha...well it depends what you do to it besides the stroker and what you do for a cr...my setup is making 430hp and 475tq but thats 9.1 compression no blower or nitrous..i kno a guy with a 10.1 cr thats running 450hp and 515tq with a mild cam and not so good heads..its really about the motor who knows...you will prolly be looking at numbers close to those 2...but along with all this hp u need a car that will support it.i got a mear 55k into mine already but im ready for that turbo i have been long waiting for...and i can see that 800rwhp coming up soon.either way hope that helps

 

Ive seen 383 be in the high 475-490 hp area and 480-520 in torque

 

A good rule of thumb on a 383 is your not going to build a whole hell of alot more hp over a 346 head and cam car but you build a lot more torque in the powerband than a 346 does due to the stroke.

 

AMEN god bless the lil torque monsters

 

Ok so if i stroke and put longtubes and FAST 92mm maf and tb i can look at a definite 450hp and over 500ftlbs?
i just want a streetable 450hp

 

Heads and cam are far more important than the throttle body at that power level. Find a used LS6 intake to save money.

 

i figure im gonna be doing this all at the same time
so why not just get FAST maf and tb
i dont want it not being able to breath

how big is the LS6 maf???
never really researched

 

Well you were saying you weren't even sure about headers right away so I assumed you might be on a tight budget. If that's not the case, then spring for the FAST intake.
If on a budget, just use a LS6 for now and spend the money on a good shortbock, heads, cam,exhaust, etc. The LS6 intake and throttle body won't cost you much horsepower at the 450hp level.

In other words, the bigger intake may gain you 10-20 hp. The heads and cam will be worth 50-100 hp depending on your choice. After you pass the 450-500hp mark, the intake really begins to be a restriction. Headers are a must, period.

 

like said above, if you are going to do it... do it right. You have to have headers, but if you are gonna spend the time and money to stroke it, you might as well put a decent cam in it and some good flowing heads. then you gotta look at the drivetrain too, cause the stock drive train (depending on how hard you are on it) ain't gonna last long.

 

486 / 462 is what I am currently putting down. The heads and cam will determine the powerband and torque. For more torque use a smaller cc intake runner.

 

Stroker kits run about $1000 im guessing
and i dont want to spend much more than $2000 on the engine at first

this will be my college car afterall and as of right now im a lil short on cash

how much do a good set of headers run?

how much hp/tq can the stock rear take?

 

you may want to admit a stroker is out of reach. Build a solid 346, it's no slouch. We all want a big inch beast, then again I want a Ferrari Enzo.

 

Unless you are doing the work, I'd expect to pay more than a grand to build a stroker. Headers will run you anywhere between $400-1000 (ballpark), depending on the brand, size, and finish.

As far as the stock rear, the results vary, but I wouldn't push it past 500 hp, especially if it is an M6. Especially if this thing gets some sticky tires. That right there would be game over for that 10 bolt.

 

lol i dont want over 500 i still want reasonable mpg

and i will be doing everything myself with my dad so its just the cost of the parts im worried about

and how much are a good set of heads that keep the compression relatively low
10.5:1 is about the highest i want to go

 

If you have $2000 to spend you will not be building an ls1, of any displacement. Not with any quality anyway.

 

stroker kits arent that costly are they?

i know my dads LT1 383 kit was roughly 900
