ive read that there is Cast aluminium Blocks from GM,Dart,World, street blocks! Then theres Race blocks?
Then iv read full aluminium blocks? WTF!
"coz of my inexperience"!
Gm Block was 90 pounds instead of cast iron block that was 220 pounds? big difference in weight? Thay say you have to get them really warmed up before driving! What about prices difference in parts etc? SBC preferred
