it's all i use! good old block from a dump truck. mine is .100 over (4.350) with a 4.25 stroke crank. this makes it a 505. i use 6.535 oliver rods in her. i have used these blocks for years and had no issues with them. i can't afford a "good block" :lol:
makes me feel good that my dump truck motor i put together in the back yard will run faster than a lot of guys "professionally built" pieces with the after market blocks :shock:
