Did some searches on the pulley swap and haven't found that much specific info. Will it boost earlier then the stock system (3k rpms)? Will the by-pass valve still function normally to reduce unwanted boost when cruising? And Finally are any of you worried about boosting 10+ psi on a 10:1 comp. ratio on a stock block? Thanks for the education and please excuse my ignorance, what I know is very limited. Just want to make my $3500 purchase worth while. Thanks
