Hi all, I'm kinda new to the site, and I heard this is one of the best Big Block Ford sites on the web. After much debate I'm planning on building a 521' motor, but need some info on the build by some season vets. I've done some homework on the Big Block Ford, but I'm still a novice when it comes to the engine. Any info and input would help alot. The car is a race only 88' LX. Thanks.
