Looking to upgrade power in 18' 2+3 in next year or so. '79 260/alpha now--would like to know comparative merits of BBC vs. SBC (maybe "enhanced" 383 stroker ). 383 appears to be suited to high torque lower rpm applications--encountered in marine usage. Concerned about weight and space ("fit")issues with BBC--also handling etc.
Bravo is probably also in the future.
Also interested in comparison of IMCO and Gil exhaust manifold/ systems.Imco slightly cheaper-- but is performance substantially different? Also muffler comparison?
What differences with either-- over stock mercruiser manifolding/ systems?
My intent is to upgrade exhaust this year-- swap engine to 350 HP 383 next year-- upgrade engine and outdrive the following.(HP to 400+ ,Bravo.)
Would you recommend other alterations first?
( I know this is probably not the best way to spend the $$-- friends tell me to instead get into a 22 or something a little bigger-- but I'm nuts about my 18-- and don't think I could ever part with it)
Thanks and good boating
