Re: Performance Lacking in a 383 Build.
Why would spending more money on parts be the solution to the problem, that's just guessing. Engines aren't that complicated. If it feels slow (but without an actual measurement and assuming 300hp) it's probably down 100tq/100hp. Unless something is broken, you won't see that kind of power loss with just
non-ideal aftermarket parts. With an "RV cam", you should see more peak torque than HP. This should feel snappy and fast when you step on it, even if it has falls on its face once you get moving.
A dyno is probably $500, and will tell you a lot more than musical chairs with nice parts. It could also save you an engine rebuild, as a lot of power issues come with incorrect air fuel ratio. An old school guy may be able to tell you something similar with a drag strip, but that kind of expertise doesn't come cheap. With a good dyno tuner, you can also make some changes and run again.
