    A lot of talk of 383's and vortech heads in recent weeks. Well I have said that the main draw back of the vortechs on a 383 is the small intake ports... well good Ole Edelbrock has come to the rescue w/ the new E-tec heads... Was reading about them for the second or third time in the new Car Craft and decided to see if they had info on their website and could post for all to see... check them out http://www.geocities.com/milnerlives_2000/blazer.htm

    We have talked extensively in the past about engine stuff for my Blazer. I think this is just another reason for me to wait a while before I change anything. There are so many new products and crate motors coming out, its hard to know what to do. I figure I'll let the dust settle and then see what things look like.
    I read about those new heads in my magazine a few days ago too. Sounds pretty sweet. I think a 383 with those heads would be a really fun motor to have. But the big block crate motors are still very tempting.
    What were you saying about those heads and being a daily driver? Is aluminum a bad choice in cold weather?

    Basically aluminium is very sensitive to heat and cold... and most times I have found that when you pair an alum head on a cast block... leaks happen when the weather temps are as extreme as they are here in MN.

    Aluminum heads on a Cast Block= mucho head gasket swaps! Its always been this way. But if they dont warp on ya, you can pull some ponies out of that setup for a while anyways! Later-
