Hi there,

I'm driving a '66 coupe with a 289 V8 and C4 tranny with power steering, no A/C
I was wondering what parts I need in order to swap my 289V8 with a 351W.

I figured out that i have to replace my distributor and may have to use swapheaders. Any other parts?

Starter? Intake? C4?

Thanks

Your oil pan and intake manifold won't fit. Hood clearance is tight with taller dual plane intake or any single plane, plan for a hood scoop or drop base air cleaner if you want a Weiand Stealth or something similar.
Your 66 will have a passenger side rad hose, so you'll need to set your 351 up like a 69 351W (water pump, timing pointer, timing chain cover, 3 bolt crank pulleys) or get a rad with a driver's side hose.
Speaking of rads, the 20" 2 core that is in your car now likely won't be enough cooling for your 351W, especially if it is hopped up at all. I don't know whether a 24" fits in a 66, but check that out or a 3 core 20" at least. A/C adds to the cooling load too.
If you set your 351W up like a 69, your alternator and power steering brackets will work with the addition of a spacer. That spacer is a one year, hard to find item, but it has been re-popped. I got mine from Wild Horses bronco parts. Here is the link Spacer
If you re-use your 289 heads on top of watching for valve clearance and compression ratio, you'll have to have them drilled from 7/16" to 1/2" head bolts. No big deal any machine shop can do it.
For headers, there are swap headers made or you can run the 69 351W manifolds or 289 HiPo manifolds. I went with a repop set of the HiPos. But I have a bias against headers...
Good luck and post back with any questions. I just did this swap in a 68 Cougar, so its pretty fresh in my mind. All that torque from a 351 is going to move that 66 around real nice.
