Here is the set up
3310lbs empty weight 71 malibu
383ci 425/460ft lbs est.
edelbrock 600cfm/airgap manifold/hei
upgraded turbo 350 and shift kit/2200stall
upgraded 8.5 rear 3.42 posi
front to rea suspension new to stock specs with f41 sway bar kit and boxed rear control arms.
25.5 inch street radials.
I ran a 9.19@77mph in the 1/8th.shifting at 5000rpm.
What modest changes can I make to this street cruiser to get solid mid 13,s in the 1/4?
The 1/8 was ran at 78degrees at about 600ft above sea level. seeems to convert to a low 14 sec qtr.

do you happen to have the spec on the motor? i think that would help others determine your time...
also, i was reading thru the archieve and it seems that people get better time if they just step on the gas with a stall converter - you might want to try that if you were foot-braking?

I think your combo has 8 second potential in it already. What are the specs(heads,cams,etc).Some sticky tires will help your 60ft times. What did you timeslip look like???More carb.

Get a 750 vacuum secondary Holley..that 600 is too small
What was your 60 ft. ?

In addition to the info posted on the 383 Malibu additional specs are
AFR aluminom heads 195
headers
2.1 60ft time
I see lots of discussion on carb sizes. I will probably run a 1/4 in Oct to test the changes. I really would like to stay away from too sticky of tires.

You're pretty darn close to mid/low 13's now at 9.19...

How big is the cam that you are running? Even with the 600 carb, i think that better times are definitely achieveable. How well are your tires grabbing?

cam on my 383 is a lunati #30112 275/285 and 225/235@.50
do these tailored barry grant demon carbs really out shine the competitors?
Again my goal is a clean looking street cruiser with a surprise for the unsuspecting tuner. These old cars set up right seem to really hammer the new iron between 30-100mph. Seems to be the torque they seem not to sell at the showroom. 70-150 mph the new iron is impressive and can still be a daily work car.
