The spare parts motor build

[Kidd]

Bruce how many pounds of boost do you think this motor could safely handle on 93 pump gas?

I don't know. I ran 14psi and 92 octane with 15 degrees of spark. It had a lot more power with 19psi and e85.

Having an 11:1 compression ratio makes the cylinder pressure about the same as stock 9.86:1 with 3 more psi. So this motor with 14psi develops the cylinder pressure that a stock compression motor would at 17psi. Those figures come from playing with the Wallace Racing calculators.

I wish I had the money to buy this off you. I'm curious to see how well it would perform n/a.

I would be interested too. When I had it na it made 337rwhp with stock heads. This was with stock cats and I was less knowledgeable about tuning. It made 347 with e85.

I'd like to think it's capable of more with the proper tuning and long tubes. It's held as much as 699rwhp and that's actual, not corrected. Ford really made the mod motors strong except for the dinky rods.

cool build! As it has been said already, I wish I could build a new motor for "fun". Every time I am having to do one it's because the last one went lol

 

[roberts]

Would this be a good turbo motor? Bruce or fuel ? Or is compression to high??

 

[JoshK]

I have basically the exact same engine except for the block. I have been meaning to get back to you, just been crazy busy at work lately.

It really depends on who you talk to. There are many cons to using this for a turbo imo. The clearances are tight so it won't like the heavier oils some turbos need. The pistons are made from 4032 aluminum like the GT500 is. They aren't as forgiving in a detonation situation like a boost spike as 2618 pistons would be.

IMO the compression would be a pro for better low end and more power with less boost. I know that a lot of people would disagree with that statement. Also keep in mind that I have zero turbo experience so everything I just posted is speculation based on others experiences.

Fuel is running almost the same motor with a turbo and making 700/780 so I'd imagine he would have some good input on his experience with it.

 

[roberts]

Well all I would be looking for is600-650 fuel can I get ur input?

As money allows I'm acquiring the parts to complete the motor. A 3v rocker arm/lifter kit came in the other day. I got around to pumping the lifters up with oil tonight. They will sit until tomorrow or Saturday when I'll give them a few more oil filled pumps and then install them along with the rockers and stock cams.

The next purchase will be an FRPP timing kit. All new chains, sprockets, guides, bolts, phasers, etc. I still need to figure out what to do with the vct. Either put block off plates on or get some housings and soilenoids. This motor may well end up in a non vct application so the block off plates would probably be the best way to go. I wonder if v10 cam sprockets can be used on a 4.6 cam? Probably not because if it were possible everyone would do it instead of lock outs.

The kit as it arrived. Two zip locks with 24 each rockers and lifters.



Lifters all pumped up and soaking.

Nice I love this stuff, my plan is to build a 460 for a notchback one day.
I know nothing about building engines but I want to work on it in my spare time, buy parts and piece it together, take my time with it...
probably in the next few years.

I'd wake up in the morning early just to go to my garage and work on my engine. that would be sweet!

 

[BruceH]

Did a little more tonight. Put the lash adjusters and rockers in tonight along with a set of stock cams.

Gave the rockers an oil bath prior to installation. The lifters had been pumped up with oil previously.



Lubed all of the cams parts up with assembly lube to make sure something will be there whenever it gets it's first start.



Stock cams. Notice that one side has a longer front end than the other. The longer snout goes on the head that's sitting farther back on the motor.

Im surprised someone hasn't picked this up already.

There has been considerable interest but that's it. I can understand. I'd be hesitant to buy a motor that was used with forced induction unless I could hear it run or really knew the seller well. Plus, this build goes against what a lot of the "experts" say about how to build a motor. High compression, tight clearances, an older generation of aluminum block, tty hardware.

I figured the low price would convince someone to take a chance on a motor that's already run successfully for 25,000 miles and survived 19psi of boost with 699rwhp uncorrected. As time goes on I'm building it up to a complete motor. It will be used or sold at sometime. For some reason a few local places will call me when they need modular parts. I can usually point them in the correct direction or help out. People blow 3v motors from time to time so at some point there will be a need for it. Or, I'll come across a vehicle with a blown motor for a good price and put this in it.

For the meantime it's a project that keeps me engaged with something to keep my mind off of day to day stresses. Kind of like therapy.

Side business?

Did a little more today. Installed the windage tray, oil pickup, and oil pan. The pan is brand new and has a bung.







Once I get enough cash together for a 3v timing kit the rest will go on except for the valve covers. Then I guess I'll look for a motorless Ford.

 

[BruceH]

Put some more new parts on today. New phasers, chains, tensioners, guides. Everything that comes with the frpp 3v timing kit.

I took pics of the timing setup just in case I have any doubts later on. The tensioner clips will be removed and the trigger wheel installed prior to the front cover going on.









The kit also came with a new front seal, phaser bolts, timing guide bolts, tensioner bolts, and front cover gaskets. It's a bargain for the parts that come with it.

 

[skwerl]

In this picture you can plainly see the oil galley plug which was missing on my head, creating a couple extra days of work after we tried firing it up.

 

[BruceH]

Front cover went on today along with a new front seal and cover gaskets. I took care to seal the mismatch that exists between a 3v cover and 1L block. I also fay sealed the engine part of the front cover to ensure a no leak build. The block I'm using suffered some power tool cleaning abuse from the place I bought it from. A thin layer of rtv on the areas they cleaned is cheap insurance against a leak. The block had to be decked for the first build with this motor because of the same power tool idiot.

All I really have left is the balancer and maybe I can scrounge up valve covers.

I got a little more use out of my $70 70 amp HF buzz box. Welded a 1 1/16 socket to an old crank gear for a crank turning tool. It's a challenge welding with 1/16" rods and 70 amps but it got the job done. I was able to weld the w/b bung in with it too. It's already paid for itself.

Looking good Bruce! You should definitely consider building these engines on the side, I really think you could make a go of it.
