351 Boss Build To Spec....Preamble.

Wow...someone asking me a question. Must be a new member!!!

REAL BOSS PARTS- Mostly not. As you stated, we have better pistons, better ignition, etc. Why wouldn't I take advantage of that? Now I feel like a liar....

Everything after this is blah blah blah.

My good friends here knows how "picky" I am about correctness. These same people also know how stupid I am...and it is stupid to try to build a 351 Boss motor for a daily driver.

That being said, I will be posting all my parts, all the markings, every nut, bolt, washer with dimensions and weight. People can judge for themselves. I am not having my parts tested for hardness, which is the only way to tell on some of these parts.

In some circumstances, will I be "upgrading"? Absolutely.

Rods/Crank/Cam
As far as I know, my rods and crank match 351 Boss markings. But as I understand the situation, additional work/hardening/etc. was done to assure they would meet certain performance levels. Can I prove mine went under this scrutiny? I can't prove it and in all likelihood they did not. But, I suspect under the circumstances I will be running them, no one will be able to tell the difference.


Lifters/Rockers
To hell with solid lifters. Roller rockers? Maybe. Under 5500 RPM where I will be running, who will know? Except those who have an ear for the CLANG CLANG CLANG CLANG CLANG or DING DING DING DING DING of a solid lifter?

Ignition
And I certainly will not be using the piece of crap mechanical points, let alone dual mechanical points, mostly because the point manufacturers make crap. HEI for me.

Pistons
Now, where am I going to get .030 over Boss pistons?

Carburation
Will I have a true Boss Holley Carb? Maybe. I am actually looking for the Holley aftermarket to go with my aftermarket intake. Got one to spare?
This is probably a stupid choice on my part as the aftermarkets were meant more for the track then the street(at least that is what the propaganda says). Although some contend the aftermarket carb was intended to correct all the pitfalls of the production model. Who knows? Where is the guy who made that decision anyway? Got to be here somewhere.

Exhaust
I have stock manifolds with BOSS markings. However the manifolds have not be opened up to the BOSS specs. Will I open them. No.

Block
My block is a 2 bolt main block. It could have been a 4 bolt for a Boss. Am I going to make it a 4 bolt. No.

So, perhaps I have to take the 351 Boss labeling back....but what else would I call it? 351 Boss Clone....maybe that would be more appropriate. Don't want anyone's panties to get to tight.

"I love my Hookers!" and "Get some Strange" probably have a different connotation to non automotive enthusiasts!

Wow...I never even thought of Boss paint....but, since you asked(I don't think I am going to live long enough for the paint to dry...)(from our friends at http://www.boss351registry.com/FAQ-1.htm)

What parts under the hood are usually painted gray ?


[This color is commonly called "slop gray" or "batch gray paint". It can be obtained at finer auto parts stores or a close facsimile. Like in 1970, Dearborn built cars received this color on certain parts under the hood.

1) Export Braces: Part numbers D1ZZ-16A052-ARH and D1ZZ-16A0532H.

2) Hood Latch Brace: D1ZZ-16707.

3) Headlight Housing Supports: D1ZZ-13BU65-B and D1ZZ-13B065-A.

4) Front License Plate Bracket.

5) Front Suspension bumper brackets D1ZZ-13BU65-A D1ZZ-13B065-B.

6) Support braces (Front fender to apron) D1ZZ-3382-B D1ZZ-3383-C.]

7) The upper shock mount cap were phosphate and oil coated.

What are the correct color codes for the driveshaft and coil springs?

[First: The correct color codes are violet, red and yellow. They are located near the center of the drive shaft with violet near the transmission and yellow toward the rear end. Second: Front springs: one gold stripe and one white strip on each of the coils. The front shock has one white paint daub and the rears have one orange paint daub each.]
What are the correct part numbers, color and paint codes for the shocks?

[Original engineering part numbers for the '71 Boss 351 shocks are D!ZF-18045-BB for the front and DOZF-180-B1 for the rear. The shocks are painted semi gloss black, with one orange paint daub on the rear shocks and a white daub on the fronts.]

Paint codes for the Magnum 500's?


[The correct paint code for the D10Z-1007 Magnum 500 is two orange daubs. The A9ZZ-1007-D magnum used on the '71 Mustang before April 2, 1971 had two white daubs on the back of the wheel. Both daubs were located on the very outside of the rim directly across from each other (opposite sides)]

Special Paint Side Mirrors?

[If a '70 or '71 Boss Mustang was ordered with paint that wasn't a standard Mustang color, it received the single chrome mirror on the driver's door. If the special paint was a Mustang color but not a Boss color, the car could have come with either the single chrome mirror or the color-keyed racing mirrors depending on the factory inventory of painted mirrors. The color-keyed mirrors were painted by the mirror vendor prior to mirror assembly, which prevented the use of special-paint mirrors.]

So... you're building a 351C-4V then. Bravo

Hint: don't use Duplicolor "Old Ford Blue." You'll never hear the end of it. Poke

You guys.......
Listen, I just have to put my .02 into the ring here. Understand, what I am about to say comes from experience, as well as the fact that engine assembly is what I do for a living at Valley Head Service, an establishment that has built engines from stock restorations, to full on Nitro drag racing bullets, for over 50 years now.
You have nothing to fear from having a line bore, or line hone, performed on your 351c, or whatever engine you have. Do any of you realize that EVERY factory cylinder block that is machined for high performance stresses, be it a Ford, a Chevy, or EVERY 331/354/392 Chrysler hemi, gets aftermarket main caps, four-bolt or girdle style, fitted to them, and they are ALL line bored to fit, and usually followed up with a line hone. EVERY ONE. I have never, so far in my career, had a rear main leak or seep due to a line bore/hone.
They can leak for various other reasons, which a seasoned engine tech will recognize and address,but blaming a commonly performed machining operation for the problem.....no.
I might add here, that, it was posted that the performance envelope of a proposed build was to be to 5500 rpm. If this is the case, you don't need, or want, a real Boss 351 for that. Even the two barrel heads will pull to that, a four-bolt main block isn't really necessary here as well, nice if you got one, but not necessary. D1ZZ rods, more expensive than aftermarket H-beams, and so on.
My realistic opinion....leave the correct part number parts to a guy restoring a real Boss 351. On the street, you can buy the performance you are looking for in the aftermarket for a fraction of the price of OEM Boss parts. Don't try to put a highly built-up engine in front of an automatic, unless you are prepared to yank the trans and throw an equal amount of money into making it shift, and live, behind a big cam. Even if you do all of that, you'll need to replace your open third member with a Traction-Loc and better gearing....which now leads you to changing out your old suspension for springs/shocks/bushings/arms/bars, etc.....see where modifying will take you if you aren't pragmatic and carefull????

Hi Mike,
There is a lot of intelligence in what you say....which is probably why I disagree on a couple of points.

Spike Morelli;235350 Wrote:IEven the two barrel heads will pull to that. D1ZZ rods, more expensive than aftermarket H-beams, and so on.

Well, the 2 barrel heads will not pull nearly as fast. Been there. Done That.



And, your right. The Boss 351 can have all the correct parts numbers...except for the block, the heads, the crankshaft with the dimple, the connecting rods, the intake and exhaust manifolds....

Spike Morelli;235350 Wrote:On the street, you can buy the performance you are looking in the aftermarket for at a fraction of the price.
I respectfully disagree in regards to engine builders with limited experience, like me, who try to put on AFTERMARKET carb, Heads, or HEADERS or a DISTRIBUTOR to name a few. And all of the problems we have with how things fit, how things have to be tuned, when they break we can no longer get parts, etc.

With real parts, I know how my car SHOULD run, how to set the timing, how to set the distributor, what kind of vacuum to expect, etc. Even with AFTERMARKET FASTENERS, such as HEAD or MAIN BOLTS, you have to use THEIR torque settings. What is up with that?

Spike Morelli;235350 Wrote:Don't try to put a highly built-up engine in front of an automatic, unless you are prepared to yank the trans and throw an equal amount of money into making it shift, and live, behind a big cam.
Well...this is true, except the only way my wife is going to let me swap out the C4 auto for a 5 speed Getrag is to have the C4 blow up on the 91, or in front of my house.

Yes I will need to replace....thank God!!!! And I will share all this with my good 7173 friends...and the majority of other users on this site!!!
