why does everyone on [TB.com](http://TB.com) say thats they are no more higher nickel than any other block? you really think GM made special provisions just for the turbo buick? i mean were talkin about 30,000 cars or so. until i see some lab results i’m doubting that urban legend.

here ya go C-nut

now the lifter valley of a 109 N/A or turbo block is beefier than that of an earlier 3.8. the 4.1 and 84/85 3.8 are very similar in the lifter valley and the 4.1’s have been proven into the 700 hp range.
