73 Mustang 351C Rebuild – Tear Down’s Final Conclusion

Thanks for continuing to follow #ProjectSportsRoof.   The 351 Cleveland has been torn down and you’ve seen the major components and their deplorable condition and it is time now to get it to the machine shop.

It’s not easy finding a good shop.  While I was hunting around for a machinist I asked a few car guys I know for suggestions and found the two that were recommended were out of business.  That is not uncommon.  It is often times more expedient to just drop in a crate  or re-manufactured engine (long or short block) and that’s tough to compete against.  I was concerned that I’d have to transport the 351C block 100 miles away to check get the work done.

While I was searching for a shop, I was simultaneously search for a re-man’ed long or short block.  Of course I was specifically looking for a closely date code 351C and I was told that those blocks are not plentiful.   I took my local search to the hot rod shops (by hot rod shops I mean, shops that sell hot rod parts) in town and the shop I chose was recommended by several.  I double checked the review that were available and these guys have a very good rep.  I’m going to withhold the name until I get the block back.

 

 


 Luckily I had the block still bolted to the engine stand.  That and my cat-like reflexes (HA) kept a disaster from occurring.

Hoisted!!!

Hoisted!!!                                                                                                                                                                    ^^^ lots of Mustang parts

Not withstanding my attempts to bounce the block off the garage floor it is finally suspended and ready to get loaded.

Tied Down

Tied Down – This is the fastest this engine has done in months!!!

 

Upon arrival at the machine shop two guys unloaded the block and I asked them to measure the current bore and the size of the crank.

The results were as follows:

The stock bore is 4″ and the measurements of the current bore is .030  under making the bore 4.030.   You’ve seen the condition of the cylinders and the shop recommended to take another .010 off making the proposed bore 4.040″.

Now the crank was measured as well and it was .010 machined from stock thickness.  Purposed is to take it down another .010 to .020 under.

The shop recommended to replace the cam, so that will happen.

This ended the speculation about the originality of the engine.  Clearly this was rebuilt at least once.

Now decisions need to be made.  But first let’s take stock of where we are and then play a little “What If”, shall we?

Using this standard formula for determining displacement:  Bore2 X Stroke X 0.7854 X Cylinders  (laid out below from a spreadsheet)

Bore X Bore  X Stroke X 0.7854 X Cylinders = Displacement
Stock 4 4 3.5 0.7854 8 351.8592
Current 4.03 4.03 3.5 0.7854 8 357.1568801
Proposed 4.04 4.04 3.5 0.7854 8 358.9315699

Just cleaning up the cylinders will move  the displacement  from 351 (stock) to 358 as proposed.  That is currently where we are.

Now let’s play What If!!!  What if I increased the bore a bit more?  Here is what that look like in displacement terms.

Taking up the bore one more .010 to 4.05″  looks like this.

Bore X Bore  X Stroke X 0.7854 X Cylinders = Displacement
Option 4.05 4.05 3.5 0.7854 8 360.710658

4.05 is the furthest  I want to do with the bore – if it’s possible.  I know one Mustang owner that has his bore 4.06″, however, I’m not comfortable with that. So we’ve increased the displacement 360.

Now let’s work on the stroke.  The machining of the crank will net little to no change in the displacement. To increase that I’d have to go with a different crank.  So what do those number look like?  Leaving the bore at 4.04 and increase the stroke yields the following increases:

Bore             x                  Bore                      x             Stroke                    x                   0.7854                    x        #Cylinders                                            Displacement

Option 4.04 4.04 3.75 0.7854 8 384.5695392
Option 4.04 4.04 4 0.7854 8 410.2075085 Basically the 400

Let’s go a bit further with the increase in bore:

Bore             x                  Bore                      x             Stroke                    x                   0.7854                    x        #Cylinders                                            Displacement

Option 4.05 4.05 3.75 0.7854 8 386.475705
Option 4.05 4.05 4 0.7854 8 412.240752
Option 4.05 4.05 3.85 0.7854 8 396.7817238 Off the shelf long stroke cranks
Option 4.04 4.04 3.85 0.7854 8 394.8247269 Off the shelf long stroke cranks

In-depth Tech: Valuable Tips For Selecting The Right Crankshaft

Cast, forged, billet? Straight-shot or cross-drilled? Experts from Eagle, Lunati and Scat offer tips and advice on selecting a crankshaft for your engine.

Engine builders are often conditioned into selecting crankshafts based solely on the expected horsepower output of the engine, or at least that often-optimistic number carries the most weight in the decision process. But savvy builders — whether assembling an honest street engine, rogue weekend warrior or a savage race-only bullet — will recognize the importance of analyzing other factors before choosing between cast iron, forged steel or billet steel.

A Look At Drifting Clutch Technology With Spec

Thought I’d share this technology.  I have a Stage 2 Spec in my Corvette and has served me well on the street and auto cross.  Chase the link below to get all the details.

For most of us, we like our Mustangs to be well-rounded. Many of us can only afford one, so it needs to be able to do a few things other than just getting us from Point A to Point B. Fortunately, we can make a Mustang be good at a couple different types of performance without making wholesale changes. It’s pretty hard to make it great at several things at the same time, but we’re willing to make concessions in order to make it more than a one trick pony. We can take it to the drag strip, that’s easy. We can also take it road racing – which isn’t as easy – but we can still have a blast provided we have outfitted it accordingly with the right brakes. We can even take it drifting.

SPEC Clutches is a company that knows after the act of drag racing, drifting is something that comes natural to a Mustang. SPEC’s David Norton has been involved with drifting since the sport’s beginnings, and knows V8 power mixed with a tail-happy suspension, getting a Mustang to drift isn’t difficult.

963 horsepower from a combined combustion/electric engine?!!!  Yes!!

Farrari Combo Combustion-Electric

Farrari Combo Combustion-Electric

It has been long-awaited for the day we see the successor to the mighty Enzo supercar. After its debut this morning at the 2013 Geneva auto show, the automotive world is in uproar over the new Ferrari icon, LaFerrari. Producing a combined 963 horsepower through a 800 horsepower combustion engine and a 163 horsepower electric motor, the new LaFerrari is the most powerful and efficient Ferrari built to-date. 0-62 in under 3 seconds and achieving 205 mph top speed. Body & chassis structure is similar to the multi-material used to in the Scuderia F1 racecar. Like its predecessors, LaFerrari will be a limited production vehicle. Though just 499 copies will be made, that’s much more than the Enzo 24 copies. Price has yet to be announced, but expect it to be north of the $1 million dollar mark.

Enjoy the video.  I DID!!!
