I was just wondering what it would take to get into the 10, 11 and 12 second range, With a carb motor. So if you could post some combo's and suspension mods, that would be great.
Thank you
Mike

 

n/a?

simple.

big cubes
big heads
big cam
longtubes
LCAs
LCA Relocation brackets
sticky tires
converter
air bag.
few weeks of tuning the engine and chassis.

thats the easy route.


thank *** we dont have such a limited number of parts that there are "formulas" and "combos".

if you read ls1 boards, or some other boards for other cars where you're limited in the selection of aftermarket parts, they have these gay "formulas" of "do this, this and this to get this result"
umm, yeeea.

 

When I build my 383 N/A I atleast want to run eleven's. Im just not to sure what cam and heads, and other mods to use to get there. So if anyone can help me that would be great.

 

Sounds like a recipe for a 13 second car to me. big this big that doesnt equal fast. There ARE formulas and "do this, this and this to get this result." Its silly to not take proven combos into consideration when you're trying to go fast. I know a ton of guys who buy fancy expensive "big" heads, throw in some huge cam, do all the other typical stuff and run horrible numbers. Then I know guys who build combos out of the cheapest simplest parts that have been proven time and time again and they run amazingly fast.

 

true. heck, i have a friend running low low 12s on vortec heads....

i'll revise my "formula" then..

heads
cam
intake
exhaust

better?

 

I think you missed a few test and tunes in there somewhere...

 

anyone have some proven 12 sec or better combo's

 

350ci
flat top pistons 10:1cr
0decked block
Stock cast crank, stock "K" rods ARP rod bolts
fully ported Sportsman II's
portmatched Vic Jr intake 750cfm holley DP
Isky 547B solid cam
Crane 1.5 gold race roller rockers
1-5/8" lng tube headers, dual 2.5" exhaust.
3500stall converter Th350
3.73's or 4.10's
low 12's@107-109MPH in 3800LBS car.
Can go 11's in a lightened car 3000-3200lbs.
Dynoed at just under 500hp.
Pump gas pretty basic

 

Heres what a guy I used to see at my local track runs in his berlenetta:

355
10:5:1 compression
Edelbrocke RPM heads
RPM air gap intake
XE274 cam w/ 1.5 rr's
650 demon carb
2600 to 2800 stall w/ turbo 350 trans
4.10 posi rear and slicks
subframe connectors,edelbrocke torque arm,LCA's
Ls1 driveshaft
3200 lbs without driver
runs consistant 7.8's in the eighth which is low 12's in the 1/4

 

I was thinkign about doing this

383
10.1
eagle kit
KB flat tops
comp XS282S cam- 2400-6800 range 520- 540 lift 282-290 duration 244-252 @ .050
AFR 190
RPM air gap
750 holley
1.6 rockers
3:42 gear
2600 stall

 

gonna need a lot more stall if you wanna run good numbers. My friend runs that cam in a 400 and hes gotta 3500 stall ...You may want even more than that for all-out straight line performance.

 

Also that would be with a 700r4. With this set up I just cant figure out what cam I want. I just want to beable to run 11 or low 12. But iam not to sure on how to get there.

 

My friends 400 runs very close to 11's and his heads dont flow nearly as well as AFR 190's. The combo you listed with more converter and gear should have no problem busting high 11's (maybe better) with a good tune.

 

See sig

 

heres a 10 sec combo in sig

 

How much power was it that you think that your car should be making? It just seems like it is going awful fast. Even screwing around w/ dd2000 I have a hard time getting it to show the power levels that I would expect you to be making. Do you know the opening and closing events on that cam? I asked bullet what they would suggest for me. They gave me a recomendation. It looks like it would be pretty strong. I emailed them and asked them about the actual opening and closing events for the cam that they suggested for me because that can make a big difference. I dont know if they give those out or not though.

Cam card is in my tool box at the shop, but I looked it up on my DDyno.

specs were at .050 lift

106 lobe serparation
255/263 int/exh actual duration
.621/.621 lift

BTDC 25.5
BBDC 61.5
ABDC 49.5
ATDC 21.5

With zero degree of retard/advance

"Supposedly" and I use that loosely, the motor on ddyno says 601 hp @ 6500
531 ft/tq. @ 5000

This was based off entering my actual head flowing data and actual cam specs so it's about as close as one could possible get as far as entering the exact data in since I had all the information to do it.

Just know it takes alot of ponies to move my heavy butt into the 10's. So generically speaking the DDyno is probably pretty close if you go by mph/weight of car math formula.
