351W - What woudl I need?
Assuming I move forward with the engine from my other post, what else would I need to install this in my 66FB? here are some of my thoughts:
- Carb 650 cfm
- Exhaust header + new exhaust line 2.5"+ flowmasters
- Transmission: I have an original ford 4 speed or a T5 (I have it handy)- if T5 should I install a torque converter?
- Rear end: ????
- Water pump
- Distributor
- Oil and fuel pump
Obviously I am novice with engines, so be kind
I am looking a nice street car with some power, but I will not be racing it ... obviously my other option would be to rebuild my 289 but it may be more cost effective to go with the 351W at that cost ...

RE: 351W - What woudl I need?
Your carb selection should be good.
You will need "swap headers" for the 351 in a 66 I advise mid length because it will be a tight fit with any headers the mid length will be easier to R&R than long tubes.
Exhaust sounds about right, but 2 1/4" would probably do..
If you have a good T-5 handy I say go for it. A T-5 will not use a torque converter. You will need a conversion kit of sorts to convert your 4 speed bell housing and a T-5 cross-member to mount the rear of the tranny.
For the rear end, I assume you have an 8" already. It will be ok with your combo, but you will probably want limited slip at some point, when you do this you can upgrade to a stronger center section.
For the water pump I would just upgrade to an aftermarket aluminum, most any brand should be fine. The 351 will have the water pump inlet on the left, the 289/302 was probably on the right. A crossover tube will need to be fabricated, or the radiator will need to be modified or replaced to facilitate this change.
My recommendation for a distributor is a Mallory HEI replacement distributor. About $150.00 for what amounts to an entire ignition system, drop it in, hook up the plug wires, hook up a single keyed power source,and go.
Oil and fuel pump should be fine stock for say a 1975 351, provided there are provisions for a manual fuel pump on the year 351 you are installing. Sorry, I cant remember the year, but I think all 351s had provisions for manual fuel pumps, but the eccentric will need to installed on the front of the cam for the pump to work...
It may well be cheaper to go the 351 route, it will be close depending on the condition of the 289. The 351 is a physically bigger engine, there will likely be some issues with the header fit even with the swap headers. I had to "modify" our swap headers with a hammer in a few spots to get the shock tower clearance we needed. Not a big deal as far as I am concerned but it is an issue none the less.
Oh,,, you might want to see if the seller knows the compression ratio of the 351, some of those truck engines had pretty low c/r. Even so, the 20% increase in displacement should more than make up for the drop in C/R.
