Installed one of those michigan motors replacement motors 5.7's w/ bravo 2 drives last yr and the motor never has run very good. the shop that installed it was shoddy at best and now i need to check timing and change plugs because of a high speed miss and it bogs down midrange. the motor says indmar on it. any idea what timing should be and how do i check it? im mean if i get a timing light, do in need to plug anything up? not really mechanic but i can do simple stuff...michigan motors is no help after sale..dont buy from them. holly carb on this- any adjustments on this? thks for any help...
