Wow that was a good deal! I just checked out Lunati web sight and their cheapest sbc crank is $700.
When I bought my Altered it had a sbc 434 with a Lunati Pro Series crank,they sell for $1,900. I've had on problems what so ever with the whole engine,she runs excellent! Regular maintenance is a hugh factor.
A bbc crank runs $800. to $1,900 check them out at
