I thought I would ask some people with knowledge. Now I plan on ordering the parts to rebuild the 351 W pretty soon. But I have no idea on what specs to follow. So I went on the net to try and find some, and I found some guys who rebuild 351 w, and sell them as long blocks on ebay.They claim to get 468 horse, and 405 ft.lbs @ 4500rpm. Now as I'm not sure as to which route to go while rebuilding, I figured I may as well go off these specs. They only use a 9.5-1 piston, but I was maybe thinking of a 10-1? Let me know. Here are the specs.

Also I'm not too sure as to the "custom" ground crankshaft? Would using a stock crankshaft make any difference? And also my windsor is a 91, would that make a difference?

 

First question is, what is your application going to be for this discribed engine?
There will be more to this than just dropping that 'long' block into a chassis, at that power level.
If for stock application then don't go with what you discribed.
There are many sources of engines such as FORD motorsports and rebuilts from a Ford dealer, Autozone etc..

 

Well, I do plan on rebuilding a t-5 tranny in the future after putting the engine in. The truck has a fairly new rear end(8.8 inch posi). Its just going to be my everyday driver, and it might see some racing(mostly street for fun).

I want a powerful engine, but it still be reliable(to the point that I'm not wrecking things because of its power).

I'm going to look for more specs, but I may just stick with those.

 

Ok. For more things to think about.
If your truck is up to 95 it is most likely Speed Density controlled.
The injection is batch fire not sequential.
The min. you need to do is convert to Mass Air and change the EEC to match using the Ford motorsports conversion kit.
Then you can drop the discribed engine in and have the best chance for success.
The injectors may need to be changed to the next larger size. This will create a need to match the AIR Meter to the injectors. Possiblely larger fuel pump. More power means more fuel volume needed.
And on and on until all the little issues are worked out.
There's more to this than meets the eye.
Good luck.

 

Those engine specs are almost identical to the build I did for my '65 AC Cobra replica.
Desktop dyno software put it too at around 460 hp but my cam was a larger; Comp Cam complete set including push rods, springs, etc. I also had larger valves installed.

I also used Holland & Sharpe roller rockers, Holly Pro Jection 750 cfm, MSD 6AL and Eldebrock Victor Jr. Intake.

It runs like a *aped ape.

Idle is pretty rough with my cam though. That cam spec should idle rough too.

With that kind of power, remove the casting marks on the connecting rods and have them shot peened. This will help them from creating stress cracks.

Good luck...

 

Alright, this is the kind of info I am looking for, thanks for the advice.

My truck is a 94' F150, but the engine I'm using is a 91'. Now I called the wreckers today to try and pick up an ecm out of a 89-94 F150 to run the engine on. No one really gave me an exact answer.

Also, by converting to MASS air what will that do? Also, EEC? Are you refering to the ECM?

 

This is why I went to Holly Pro-Jection
You can tune it to the engine you build.

 

When you ask about EEC/ECM this tells me you will have a difficult time making the conversion with yard parts without prior experience.
Get the Ford motorsports conversion kit. It includes the harness and the ECM ans air meter.
EEC/ECM is the same referral to the engine computer.
You will be converting from one to two oxygen sensors, then what is to be done with air injection etc.
There are wire changes to be done in both the injector wiring and some other areas to get the system all into concert with each function that is different than the S.D. system, if you try to do it with yard parts but that's up to you.
Then for faults after the system is installed can be a job to figure out on this kind of work unless you know how the system works.
You now have to become the expert on what you have and many garages won't touch it.
