Vegeta Posted November 10, 2003 Report Posted November 10, 2003 What does the aluminum block do for performance though...nothing. Its lighter by about 50 pounds and thats it. Id have to see it to believe it anyway, not many people have that block, especially as a roller setup...considering it was designed as a flat tappet cam setup. Quote
93GTP Posted November 10, 2003 Report Posted November 10, 2003 Other than being lighter, aluminum blocks have no advantage, aluminum is way weaker than cast iron. I hate putting bolts into aluminum, you never know whats gonna happen, especially something like head bolts. Quote
