I got out of racing 8 years ago and sold most of my racing stuff. went to the track a few weeks ago just to watch and got the urge to race again. I figured my 67 barracuda notchback street car would be a good choice to race in the street class and keep things affordable. The car has full interior, all steel except a fiberglass hood. The engine is a mopar performance 380 horse crate engine with a 750 vacuum secondary carb, doug's headers, pertronix 3 ignition set at 35 degrees total advance all in by 3000 rpm. trans is still fully automatic 727 from 727 specialist with an 11 inch 727 specialist converter advertised 2400 -2600 stall. rear is 81/4 with 3:55 and a new sure grip unit. I run 28 inch tall tires on street but I have a set of 26 x 8.5 slicks so I put those on thinking it would help the effective gear ratio. I ran the car this past week and the car hooked well, never missed or popped or hesitated but the best time was only 14.21 in the 1/4. 60 foot times were 2.05. 1/8 mile times were pretty consistent 9.16 to 9.18. it made no difference leaving the car in drive and letting it shift itself at 4500 or shifting it manually at 5700. I know I need a better converter but I want to keep the car drivable on the street and would like to keep the 3:55's. I have been told switching the m1 intake to an edlebrock air gap would help. I know for bracket racing the car just needs to be consistent but it would definitely be more fun if I could get into the low 13's or high 12's. What do you guys suggest? I should mention the car has 21/2 inch exhaust with flowmaster 40's that dump at rear axle.
