Just like the title says, what is this. Got any pics? What is the diff? I was told 4 is better. Is this true? Can I convert a 2 into a 4?
even a 400hp B-body will be smoking fast, and i know people with over 400hp on Impalas so i dont think it makes that big of a differenceI am asking is because I am getting a caprice with the LT-1, only problem is the caprice LT-1 is a 2 bolt main. So my alternatives are be happy with a max 400 horse beater, swap engines or ???? Oh and all of this is on Fantasy Island right now. I am gonna get the car real soon but won't have money to dump into it for a while because I am dumping all my current funds into the stereo, rims and a drop.
no, there were two different castings, 509's were better...there were:hey polecat, doesn't 400 sb chevys only come with 2 bolt mains...there is an option some machine shops will do where they turn a 2 bolt( l o l ) main into a 4 bolt angled ( \\ o // ) main, which is stronger than the normal 4 bolt( ll o ll ). i think it's an rpm based upgrade mainly.
