first trip to the track
Hello, I took my car to the track for the first time and although it ran a little slower than I though it would, I am pretty happy with it. I just wondered if you guys had any idea what difference cutouts and 4.10 gears would make. The carb was giving me some trouble to the point where it loaded up so bad that the motor actually shut off a couple of times while shifting into second gear. I have a 1000 cfm pro systems carb that is getting rebuilt for the street as we speak that should work a little better. Below is my current setup
Car:
1972 ventura (probably around 3500 lbs with driver)
Motor:
496
9.5:1 compression
950 willies carb
ported 2.19 1.88 valve 049 heads
port matched victor jr intake
248 254 @.050 .600 lift solid flat tappet cam
pro magnum roller rockers...
Exhaust:
2 1/8th inch Super comps
2.5" exhaust out the back with flow master 40 series mufflers
Tranny:
Turbo 400
3000 stall
Rear end:
12 bolt posi
3.55 gears
cal tracks
Hoosier QTP's
The car hooked just fine, but obviously struggled off the line due to the gears.
On the runs that went well, it did not stumble anywhere in the run.
60 ft's were right around 1.9 for all runs
Best 1/8th mile time was 7.98 at 90 MPH
With gears and open exhaust I was hoping for something in the 7.3 to 7.4 range. Do you think that 4.11 gears and open exhaust could get me there? What do you think the effect would be?
Thanks a lot
Adam
