Hello, I am the proud new owner of a 1988 25' Bayliner Trophy / Command Bridge with a 5.7 / Volvo Dual prop for power.
I intend to use it for offshore fishing here in California. I plan to add fuel tank, and try to maximize economy and reliability.
The engine is a 350 chevy with iron heads, it has center bolt valve covers and is carbureted. Is this a first gen small block?
I plan to start stock piling parts to build a new engine for it.
My first thoughts are to start with a core from a 87-88 corvette maybe a L-98 350 TPI with aluminum heads.
My corvette could knock down almost 30 mpg at about 1500 rpm.
How difficult would it be to step up to an LS series engine?
I will be balancing and blueprinting this engine, with new pistons to achieve compression ratio of about 9 to 1
Are there camshafts available designed to maximize economy in the 1400 - 4000 range?
And will they still provide enough power to get this big boat up on plane?
What kind of performance / economy are other people getting with 5.7 and a dual prop?
Thanks in advance, Roy
