Does anyone know the weight of both the 4000 and 5000? I am trying to figure out how much hp I would need to match a 5ktq if I was running a tweeked 4000q. I am assuming the 5ktq will also have been modified, but only with the 60+ hp upgrade from Intended Acceleration. Thank you in advance. Andrew Shea 87 4000cs 120,560k miles 66 Mustang Convet. 56,000
