Go Mark... go!

As for the engine mounts, I started with 67 - 72 brackets and reworked them from there.

With my bracket "magic" and Mark's firewall and rear trans mount work, we got a good 1 1/2 inchs of engine set-back and set the engine as low as possible in the chassis... all good stuff for weight distribution.

Have fun riding!
Thanks and yes... we had a great day on the slopes.
Clocked another 400 miles on my butt, driving a car... that brings me to a 1200 mile total for the long weekend. ( I am standing as I type this... :roll: )

It sure sounds like this car is now on the "fast track" to at least moving under it's own power! :D :D

I thought I would add some text to the photos I took during my "house call" to deliver the Guzzi engine.
Here is the car, a 62 Valiant with the roof lowered and going for the "Rat Rod" look:

Image

Upon arriving, we quickly unloaded the parts from the wagon and I bolted the trans to the engine, installing a great looking 8 inch torque converter into the assembly. We screwed-on the special motor mounts and the fuel pump, placed a lift strap onto the assembly and up & into the car it went.

Image

Mark called-up his friend Randy and asked if he wanted to help, Randy was on location before Mark hung-up the phone... Randy drives a nice clean, all factory 65 Dart 2 door post car so he knows what a SL6 is all about.
I snapped this "mug shot"... smile!!

Image

We quickly got the engine/trans down into the chassis but we were 1 inch forward of getting the mount studs into the K-frame "eyelets" and had the head touching the firewall. I was starting to list options when Mark walks up with 2 big "cheater bars"... a little push here and a pry there and the assemble dropped into the holes. 8)

This shot shows how close to the fire wall the head is but hey, the engine is in there and it does not touch.

Image

Here is the other side, note how the fuel pump is now over the engine mount bracket, the bracket has a notch to allow room for the fuel pump.

Image

After a few "hi 5's"... I grab the Clifford shorty headers and mock those up, knowing darn well that we would have clearance issues. The good news, the rear header fits well and dumps out in a good place. The bad news, the front header lands right on top of the steering box and interfers.

Image

Image

With the intake manifold in place, we marked where the front header will be modified. There is enough room between the bottom of the intake manifold and the steering box, to allow the collector to be rased. Some heating and bending is in that header's future. I really don't know why Clifford does not rase that front header's collector a couple of inches, that would save everyone a bunch of hassle.

Then I was back under the car, fussing with the rear trans mount when Mark blew the "quitting time" whisle. We wrapped up the next morning and I was on my way back home, with a wagon full of parts!
Mark gave me a bunch of stuff that he "won't be using"... I made him keep some of the stuff... I think he will be using it :wink:

Doug, what a great view that 62 is. I bought a 62 Lancer about 5 years ago, now I know what to do :-) Do you mind me using your top chop design?

Doug, that is one of the "koolest" '62 rides I've seen. :shock: :D
That looks great.....I never liked the small '62, but that one is Fine! My regards to the builder :D ........

Moto Guzzi Mark (Mark Ethrdge) gets the credit for the car's concept, design and "top chopping". :twisted: Me, I am the engine builder and camera man! :lol: :wink:

Mark is a true fabricator, one of those people that is not worried about thinking "outside the box" and he really knows how to work metal. He made the first "new" VW Bug convertables by paying top dollar for one of the first hard tops off the line, then he took it home and cut the roof off of it! :roll: :o

We both agreed that it is a good thing that there is 375 miles between us... if our operations were any closer, the automotive world would be in for some surprises.

Post subject:  Back to the other "Twin"...
OK, now that Guzzi is in good hands, it's time to get back to "Requel".

The cranks came back last week and look real good.
As you remember, we sent 2 different forged SL6 cranks to the shop, both had problems with the rear pilot hole. Here is the before photo of the rear pilot holes.

The repair on the "hacked-on" crank went as planned with the repair ring pressing-in and taking a skim cut to center the ID.

Image

The early "small pilot" crank turn-out even better, it's now has an enlarged pilot hole and there is still .050 worth of hub wall to center-up the flex plate.

Image

The early crank is actually a pinch lighter and more "streamline" thru the counterweights so we did the "full treatment" to that one. It got oil hole "banana grooves", deburred, shot peened, ground .010 / .010 and rebalanced... on top of getting it's butt "reamed-out".

OK... no more excuses, it is time to put this baby together!
The next step... mock-up the cam & oil pump to check the gear mesh pattern. Then install the crank and #1 piston assembly, in order to set the cam timing and measure the final compression ratio... stay tuned!

Thought you might be interested in my "61 Valiant. I have a 2 inch setback and a 2 inch to the left, your drivers side our pasengers side. I set the engine back more to get a good size radiator and A/C Condenser and moved to the centre to get more room for the brake booster etc. on my right hand drive. I suppose it must help the weight distrubution though.

Very impressive.we do have a advantage to sitting on the better side of the car for torque reasons.wondering if your toilets really swirl the other way.or is that a rumor?Guzzi Mark

Post subject: 
Don't know about toilets but water and cyclones definately go anti clockwise.


Subject: D3) Why do tropical cyclones' winds rotate counter-clockwise (clockwise) in the Northern (Southern) Hemisphere? Contributed by Chris Landsea

The reason is that the earth's rotation sets up an apparent force (called the Coriolis force) that pulls the winds to the right in the Northern Hemisphere (and to the left in the Southern Hemisphere). So when a low pressure starts to form north of the equator, the surface winds will flow inward trying to fill in the low and will be deflected to the right and a counter-clockwise rotation will be initiated. The opposite (a deflection to the left and a clockwise rotation) will occur south of the equator.

NOTE: This force is too tiny to effect rotation in, for example, water that is going down the drains of sinks and toilets. The rotation in those will be determined by the geometry of the container and the original motion of the water. Thus one can find both clockwise and counter- clockwise flowing drains no matter what hemisphere you are located. If you don't believe this, test it out for yourself.

doug i noticed on guzzi engine that it has a mechanical fuel pump, will it be backup with a electric or is it a v8 pump with a modified arm to fit a slantsix
Author:  Doc [ Thu Feb 21, 2008 9:34 am ]
Post subject: 
The fuel pump is currently a stock pump, it will be backed-up with an electric pump, back by the fuel cell.

I tend to "push & preach" a "just get it running ASAP" approch with this type of project because I do not' like to see newly assembled engines / trans, etc sitting for long periods of time.

We all know that there will be many days of "sort-out" once the car is running, especially after it makes it's first dragstrip pass.

Do you normally use an electric pump and just fabricate a simple block off plate for the Fuel Pump hole in the block? At what point will the stock pump not keep up and an electric pump is deemed necessary?
