1975 Chevy Monza

I saw this forum and thought I would join in. I have a 75 Chevy Monza with a 350 and a turbo 350 trans. The motor has Dart heads, shorty headers, Torker intake, 650 double pump carb. On 13" street tires it runs 13.60s in the 1/4. After that I installed five lug s10 axels and put on 15" tires. Slowed a little but still runs in the 13.6 range.
