Need info on c/ratio and valve sizes for 300ci
Greetings ,first time here so hope I'm doing it right.
I have a british Ford D300 truck fitted standard with the 240 which Ive just replaced with a recon 300. Vehicle weighs approx 5.5 ton.Motor is standard apart from electronic ignition,headman headers,offenhauser d/p and 390 holley.I'm looking at reconditioning the 240 head with larger valves and roller rockers that I already have.
Seeking advice on optimum valve sizes to improve torque and can anyone tell me what approx c/r I would end up with if put on the 300. sorry know nothing about the specs of the reco 300.
Regards and thanks .Steve
