New to outdrives, so not sure what I can do with the motor. I have a '79 Spectra, 24 footer, it has an all stock 330 HP 454 with a TRS drive. I am going to upgrade the fuel pump to an Edelbrock unit, add an aluminum intake and Holley or Edelbrock carb. I figured while I am at it, throw on some fresh 049 heads that have had some work done to them. If I'm doing that, what size cam should I put in it? I have a new 292 hydraulic sitting here, just don't know what that (if anything) would do to this tug boat.
