It would vary on how you purchase the heads etc. I puchased the heads bare and got parts at a significantly reduced prices. Off the top of my head I don't think my heads totalled over $3100. That's for the 218cc 3V's. HP/Torque differnence I can only go by feel till the car hits a dyno. Going by feel I've had a substancially large increase.falcon coupe said:Brenx, how much are 3V`s worth ?
also how much hp/torque dif is there ?
