    Default My Chevy Vandura mods

    I have an integral head 250 in my van. Two barrel carb , no cat, air pump and egr. It will fail.[ head cracking]

    Just passed aircare.
    Looking for a head and manifolds that would keep the emissions where they are and improve power or gas mileage. Must be drivable in the winter [carb icing].
    Stovebolts cast iron exhaust manifold looks good.
    A 292 intake maybe, but I'd have to see one first.
    Have to figure out which year head is the best.
    I like 12bolt.coms head mods, maybe buy a head from him?

    Dump the carb and air pump and go TBI. Still pass aircare. I'm familiar with the GM TBI [S10]
