    2bl vs 4bl

(Volvo ran 715cfm vacuum secondary props for their 275hp and 310hp V8's for years). however those motors had a slightly different cam and heads than the typical mercruiser. a spread-bore is slightly better than a square bore for the average...

    Price for these parts and where to get them for a 1995 Silverton Marine 271 Express

    5.7GI-300-J: left side cylinders not firing- ignition issue???

    welcome aboard. your motor has a distributor, and with the firing order, there is no way that only one bank can not fire. That can only happen with a COP engine (coil on plug) cam retard and ignition timing are two different things. when was the last time you had the injectors cleaned?
