Commander 351 upgrades

just be sure and get a holley kit and not some other brand of kit to rebuild the carb. Also take it to someone that has a 5 gal bucket of carb cleaner so that the carb completely clean. Using spray carb cleaner never gets everything that needs to be cleaned.

IF the carb is proper, its typically jetted spot-on, there is not much to gain unless you dink with the top end.

forget the intake and carb unless you are going to install a new cam, waiste of money, you're only going to burn more gas and not get any more performance.

The only thing I would suggest is upgrading to electonic igntion, either replace the points with a conversion or better yet upgrade to a new electronic dist. That will improve gas consumption and improve starting and idle. The intake will help slitghtly and i would rebuild the carb before i ever would replace it. The intake will produce a slight improvement not really worth the cost unless you are going to change the valve train then you should replace the intake.

Well, I plan on taking the boat in for a good once-over and to troubleshoot the loss of power issue that we've already discussed, and it's got me thinking...

Are there some reasonable engine upgrades that might make some sense?

In particular, I was thinking of a carb/manifold and distributor.

I'm not really interested in pulling the motor or even the heads, just some minor updates to increase performance and reliability.

thanks
