MARINE INBOARD VS. REGULAR SMALL BLOCK

[Miles Offshore]

back in the eighties a lot of folks down my way were putting big blocks (454's) in both their inboards and i/o's. Bottom line was too much weight and i dont know if there are any left around here with that configuration. i would also make sure you had the heavy dutier gear than its sister- i dont remember the series off hand- with that lighter weight and all those extra horses she ought to run good. I dont think the pocket drive inboards can handle 40 knots though either. Maybe gary will chime in here-
