I'm not a Big Block guy per say but I may be one day, so I've bought 9 390's, one 428, and a 460 just in case I change my mind.
The books that I bought to help me understand the FE motors are;
High Performance Ford Engine Parts Interchange ISBN 1-884089-33-X by George Reid $20 to $30
Ford Perfomance by Pat Ganahl ISBN 1-884089-27-5 $20- $30
How To Rebuild Big-Block ord Enginds by Steve Christ ISBN 0-89586-070-8 $18.95
Building the motor is part of the fun.
