yeah,there is,,get rid of the turbos,,they act like mufflers.

Two pages and nobody’s pitched a cam from Bob ?

easy there or else black SUV's will be pulling up to take away your computer

You don't want a "choppy" cam in a low compression turbo 454 with cast components. The cam dictates the Rev range where the motor is most efficient at making torque. Your cast motor should be kept below 4900-5000 rpm.
We also have no idea how well the turbos will spool up with a cam that has a torque peak way faster than your "planing rpm".

If somebody ran it like it is, then start there.
You really shouldn't jump so far ahead of yourself.
Besides, you need to creep up on speed with your new hull..

Find the casting numbers on your pistons and send photos.. Find the casting numbers on your heads. Find the stamped number's on the face of your cam. Those are good starting info we need in order to help you..

Much appreciated once I get time to tear into it for maintenance before slapping it in for summer il get all photos and info

Now that’s funny! 😂

Ass u ming the engine is truly a 330hp 454 base, and me having 0 turbo exoerience, i would put this one on a list of considerations:
