1) How do I know what flexplate I need? 351W to a 65 c-4 . The 351 has the Harmonic ballancer on it .. but no flexplate (I assume the flexplate from the factory 289 wont work?)
2) My 289 Accesory Pulley is a 3 bolt, and the 351W is a 4 Bolt Balancer...where do I find the v-belt 4 hole pulley, or is there a dual pattern ballancer? (The pulley on the 351 is serpentine)
3) Have heard of people putting 289 heads on 302 for compression bump. Any advantage of using 302HO heads on a 351W or are they the same?

Hi

289 Flexplate should work.

Yes, there are some dual pattern balancers

Be sure to get 28oz balance damper / flexplate.

Don´t know the chamber volume of the HO heads, but when it is á late 351W (after ´77 I guess), the chambers have 69cc volume.

All 351w's are 28oz imbalance, just like your 289. Many items can be used on both engines. So.....

1. Yes your 289 flexplate will work. Just besure that it is in good shape and has no cracks around the bolt holes.

2. Dual pattern balancers are readily available from places like Summit. Again, you must specify a 28oz imbalance (if there is a choice.) Actually your 289 stuff will work, if you wanted, but you would have to swap several items to make it work properly--balancer, pulleys, timing cover, waterpump, and brackets. the alternator would require an head adapter from an early 351w. Accessories like PS or AC would require special adapters.

Four bolt balancer pulleys appeared in 1970 and continue to be used (AFAIK.) You can use one from a 302 or a 351.

3. AFAIK, there is no gain to swapping stock heads on a 351w. You need to be thinking aftermarket if you want a decent head.

Ok.. so I will need the 28oz Imballance ballancer.... The 289 has complete front accesories...and I'd like to use them...mainly for the AC. If I used the 351W front setup I would have serpentine, but only have power steering, no AC. I can use whatever I need to off the 289 to make it work. Covers, Pumps, Etc.. Will it all fit? The 351W water pump is on the wrong side anyway. So I need to lose that one. Who carries these head brackets everyone is talking about?

A friend made the head brackets for me on a CNC milling machine.

They connect the two threaded holes above and below each freeze plug on the front of each head. Simply measure the distance between these two holes and make a 3/8 thread hole right in the middle. Thickness of the spacer brackets is the same as for the old 289 brackets for the alternator and PS pump.

When you want to use and old AC compressor, you have to get a 351W AC bracket, for example for a 69/70 Mustang. I think this would be quite difficult to fabricate on your own.

In this case, the AC bracket replaces the head bracket for the PS pump.

I hope everything is quite clear, my english is not the best, sorry.

You can use all the front 289 stuff, except the brackets will need the appropriate adapters. My 393 uses the 289 water pump, fuel pump, timing chain, timing cover, balancer, pulleys and fan. You need the special 69/70 year stuff to mount the various brackets for AC, PS, and the alternator.

You can mount either water pump to the 289 timing cover. If you switch the timing cover, you will need to watch the timing cover to fuel pump eccentric clearance.

Ok... so where do I find the brackets I need to run the 289 stuff on the 351. I understand swapping the cover, pumps, ballancer and pulleys, But not sure where to find the brakets to help me fit the accesories on it. Must keep my AC as well.

Sorry, but I don't know. Older 351w cars (they will be 351w "only" items) around 69-73 are probably your only source after 30 years. The 351w was available in many different vehicles so lots of them were installed.

Checking out old local junkyards is your best bet. Secondary sources are Ebay, Mustang "specialty" shops (often have parts cars--such as CJ Pony Parts), or even a search of the net can help you score. You could even post a "wanted" on web sites, such as Ford Muscle (in the appropriate department.) If you found the parts here, you would be supporting the people who are trying to help support you.

About 2/3 of the way down this page are the power steering pump and alternator adapters you need:

At $13.99 each, they are practically giving them away.

65custom500, doesn't the AC unit bolt to the head? If so, only a longer belt should be needed.
