My intake is a weiand team G single plane with a 800 holley DP carb. HEI dist with MSD coil. The trans. is a turbo 350 with a 3200 stall and the rearend is a 8.5 ten bolt 4.56 gears. The car is a 1971 nova that weighs 3100lbs with me in it. I recently took this car to the strip and with slicks went 12.80 at 101mph at Heartland Park in Topeka Kansas. What am I doing wrong?
Like everyone has said the heads are a little small.
I would also like to see a min. of 12.5 to 1 for a comp. ratio.
If this is a true drag car then I would run a 4,500 to 5,000 stall speed.
What are your 60 ft times?
