A good second hand 3.9 is probably the cheapest option I went for a P76 (4.4) partly because it was supposedly fully reconditioned for $3000. It was'nt. Heads cost me $2000. The modifications to fit the P76 took ne a while & I spent another $200 on things like the flywheel that i could not make myself.
