I have a 98 SS I would really like to get in the 10's n/a. I'll list the mods I plan to have on it and will see if you guys think it can pull off a 10 second pass. Also add what you think it wou put down to the tire if you'd like.. Also if you have a smilar 383 setuo let me know what you have ran! D/A will likely be in the 2-2500 range.

Engine mods:

Alum 383 stroker
Tsp 5.3 stge 2.5 heads
Ms3 cam
Ls6 intake
90mm TB
ram air

Trans mods:

Rpm lvl 6 4l60e
4000 triple disc circle d stall
Cooler

Other mods:

Weld rts 17" skinny fronts
Weld rts 15" rear with 28" MT DraG radial
No a/c
Spare removed

Well I have a 370 LQ9 with those same heads and a cam almost identical to the MS3. Fast 90 with ram air, full exhaust, T56, etc... No current dyno numbers or track times with the new setup but it's strong enough to be a drivers race with my buddy's 500 rwhp ported/pullied 03 Cobra

I do not see that setup going 10's in that DA unless you pull some weight out of the car.

With that setup, consider going to a fast 102 intake. That'll be worth some ponies over the LS6 intake - especially keeping that 383 fed. NW throttle as well

I think it will go 10's. I have mildly ported 243's and have the trap speed for 10's. Just haven't gotten a chance to get to the track with drag tires. Your lighter also, so I think it could pull off high 10's.

I think it's possible but a challenge.

I got my 3700lb chevelle to go 11.46 with hard ported 799s and a 230/238 cam. An fbody of the same weight would likely be a tenth or 2 faster than that due to aero. Add in a couple lbs weight loss and having more stall, more cam, and likely slightly better flowing heads and it's possible.

What gear do you have? 3.73 or steeper will help you

When I start thinking about paying for a fast and all that I may as well save and do a 408 with ls3 heads

I ran a 12.3@110 with my first bolt-on ls1 with a small 3200 stall and nitto dr's. so that kinda makes me think a h/c 383 with drag setup and a bigger stall should do 10's.

not 100% but I think they are 3.23's

I would think you have enough to go 10s if everything is dialed in. I would definitely put in some 3.73 or 4.10 gears though.

As mentioned by Darth, LS6 Intake choking the rest of your combo
Big time. FAST 102, 20-25 RWHP out of the box plus torque throughout
The whole range at least 2-3 tenths, MAMOFIED 30-35 + vs LS6
on your combo 3-4 tenths, maybe more.
3.73s if you don't have will help a lot also.
Good Luck

I hear you there. But your talking about modifying a LS6 intake already for a 90mm throttle. For a little more you get the 102 throttle and the larger plenum volume. I think your 383 will get into the 10's. Agree with gearing. Also traction, but I saw you're talking 15" rears with wrinkle walls already so I'm assuming you've got a plan for traction.

It's possible it would get a fast in the future, but I also plan to spray the car and I don't want to blow up an $800 intake.... I've had about 5 different fast setups on previous cars and I think they work great, but on a little bit of a budget with this car. Have to cut down in a few area's.

Or should i save for 408?

I would definitely upgrade to a nice ported 102/102 setup. That alone will give the car a nice kick in the ***.

Instead of building a 408 or 383, put more money in the top end and just rebuild the 346. Save a ton right there not buying a crank.

Mamo 220's
Mamo ported Fast 102
A cam with smoother lobes then the MS3, unless TSP is now making that cam with the callies lobes.
Good lifters(Johnson 2110's)
Mamo YT rockers
1 7/8 LT's and a good TD exhaust(kooks)

This will be a 10 second capable combo at your weight and track DA.

It looks to me like you will certainly have the power/weight to run 10's, even at that DA. If you don't, it will be the gearing and suspension holding you back. What are your rear suspension mods?
