Hi all, I'm needing some advice.
I have a 1996 Starcraft 22' cuddy with a 5.7 2bbl. alpha one gen2. it runs well, has 150 psi on all cylinders. running a pertronix electronic marine dist in it also. Ive had it two years now and I would like to up the HP and looking for cost effective ways to do it. I considered going EFI but OMG that seems to be pretty pricy, so Im looking to the old school method. 4bbl carb, intake and cam. now for the questions.
merc or aftermarket intake?
square bore or spreadbore?
which carb? holley quadrajet edelbrock etc
and what kind of lift and duration cam can I use without having to machine the heads for bigger springs or create more problems.
and finally what kind of HP can I expect to gain?
option B is to drop a 383 in it. but then the same questions for parts would apply as well. but more costly since I would need to rework the lower end or buy a short block.
I have plenty of street performance experience and building engines, mostly big block though. but marine seems to be entirely different so I felt asking more marine savvy guys than myself would be my best bet.
