Last night we got our driver behind the wheel for the first time!  Since the truck is nowhere near street legal, he drove it around our place in the country a bit to get a feel for the steering, clutch, and brakes.  Then he drove from the end of our driveway up to the house, which is roughly 1/4 mile of uphill gravel, over and over.  By the end I got him to push rpms up close to 6k, and he was never able to get the truck squirrely or out of sorts.  That means we can pull the practice motor and install the race motor!!!!  Its getting close to race time.  This is getting real!

Our driver is bringing his RED video camera along, and we'll have several GoPros mounted in/under/around the truck.

We scratched last year - too much to get done and too large a chance it wasn't being held.  The salt was awful.  This year looks the most promising in a decade.

After Thursday. I realized that I never should have pulled one of the leaf springs out of the pack to soften the ride.  Now that we have ballast bolted in the box, the springs sagged enough to make the axle touch the frame on the passenger side, ever so gently.  I reinstalled the second leaf in the pack, and now we have a LOT more room.  I also moved the entire crossmember and rear driveshaft loop up about 1 1/2" to allow more clearance.  

 

I don't think we can get the truck any lower without risking digging up the salt, which would not make us a favorable race team.  

 

In preparation for the race motor, today I installed an Aeromotive 13 psi fuel pump.  It should provide the volume we'll need to the 50 mm DCOEs at 8000+ rpm.  In case it doesn't work, I made the mount universal so we can bolt the classic Carter pump right back in place.

Thinner drop block?

 

For what?  Thicker lowers the truck.   I gained clearance by adding back in the 2nd leaf spring from the top.  I though we could do without it.  We have roughly 1" of suspension travel now, with 350-ish lbs. of plate steel in the box.

The practice motor just came out of the engine bay.  No more screwing around.  This shit's real now.  Once the flywheel is resurfaced, the race motor goes in, and all the BS that goes along with a custom install has to happen and right quick!  It may take me a month to get the Webers dialed in so we can get on the chassis dyno.   The only good news there is that the dyno session will be free - repayment for a huge favor on a Sunday for the dyno owner.   :thumbup:   And he's stoked to see what it'll do!  Surprising for a guy that only works on Mustangs.  

 

BTW, the favor was shaving the nose off a '13 GT350 overdrive crank pulley that kept throwing belts when its making over 650 hp.  Cool stuff.
