Oh yeah to answer the question a bit more specifically. I have a BB with B1 heads and a KB block. Only fiberglass is front end, lexan windows. One seat with door panles. Car is a full 2"x3" frame rail tube chassis with 25.4 cert mild steel with struts up front and a 4 link out back. Car weighs 2840 as it sits full of fuel with me ready to race. That includes 27lbs of ballast under the radiator....oink oink
