what parts are needed to change the rotation from standard to reverse rotation on a 351w?

there is no substitution for cubic inches.

Depends what year of engine you are working with.
If it is a 2 piece rear main seal you will need a completely different crankshaft.
You will need a proper distributor or a gear to swap onto your existing distributor.
You will need a different starter.
You will need a proper rear main seal if you are running a one piece rear main seal engine
You will need a new camshaft/lifters.
You will need to index the transmission pump the opposite direction if it is set up for std. rotation.
I believe the reverse rotation engines take a specific vibration damper as well
It's early I may have forgot something.
I would suggest just looking for a running take out if you can find one unless you are building a fresh engine anyways.

Zach, Would it be possible to just change out transmissions and let it reverse the prop shaft rotation???

I think I'm confused,
Here's a link to your thread from a year ago,
Seems like things are changing

Harmonic balancer isn’t functionally different but the timing marks would need to be reversed if using anything other than 0deg/tdc. Index the rwp also if you’re converting a bobtail lefty to righty. Otherwise Z has the bases covered.
Short answer to Duane’s question is no... long answer is yes/maybe/sort of but not inexpensively. Ie, you can make a LH engine turn a RH Prop with either a Pcm 1.23 or ZF63, but those are $2k+ gearboxes, plus you’ll need a new shaft and propeller to match. And you’ll need to confirm the longer body (versus the velvet 1:1) fits in the hull.

Thanks TR. On a side note: did the new clutch pack ever get tested??

Thanks to all. I guess I will keep the eng as is since everything is brand new inside. I will clock the trans correctly and get a left hand prop. Anyone have a spare left hand prop they would part with? This is for a fish nautique.
