then at least take the crank to be measured/polished? also what is the intended use for the car? if it's primarily a street car the 383 will be more than you'll 'need' even if it's less than you'd ideally 'want'. we all tend to get greedy when planning an engine build and then don't use half of the performance available to us. seems a waste to me and only done for bragging rights, lol. if ultimately you do want 'big' power it'll mean a 400/440 block to start and saving for a big power build. you may as well build the 383 for now, you never know it most likely will be enough. if not at least you already have the big block swap parts already sat there. oh, and someone will buy the 383 when the time comes too. at least you'll be out driving rather than saving for the 'big' power build while looking at the 'dead' car with no motor sat in the garage.
neil.
