the plan for the next motor is for it to run on E85

the car has full return fuel line system with 3/8 stainless lines under the car. I have a couple of feet of flex lines at the tank and engine ends to make the connections easy and to control vibration to the hard lines.
So I am removing the existing rubber lined flex lines and swapping in PTFE lined flex lines.

The flex line material that is E85 approved with a PTFE inner liner takes a fitting with an internal ferrel.
it is still hand assembly, no special tools required. The PTFE hose is a slightly smaller outer diameter, because the PTFE inner liner is much thinner than the rubber liner in regular stainless wrapped flex hose.

progress on the motor block

inside: Gyptal 1201 Red Enamel
outside: IH Engine Red

concerning the casting defect shown in the second photo......
Chrysler had a grey iron foundry in Indy through the early 2000's.
Called the Tibbs Avenue Foundry, had previously been The American Foundry.
Its all gone now.....
They implemented a molding upgrade in the mid 80's called Impact Molding.
One disadvantage of Impact molding was it produced very hard molds. A hard mold will have
lamination that will break free and float when shocked by the hot metal inflow.

I believe the photo is a mold scab. If the mold scab had floated to a bearing bridge or head face area it would have scrapped this particular casting. As it is, it resides in a non critical stress area, does not leak,,,for me is an interesting curosity.

Is this just to help drain back? Help me remember. :D

Help me remember
well,,, I am more than a bit of a neat-nick and I like the way it looks.

Are there benefits beyond the aesthetic?
My thought process goes like this:

* Is there windage drag in the crankcase when the motor is at speed?
Yes. A Yes is good.

** Would smoothing the crankcase walls have the potential to reduce the effect of the windage drag at the crankcase walls?
Yes. A Yes is good.

*** Does the Red Gyplal paint smooth the interior crankcase walls?
Yes. A Yes is good.

**** Are there potential downsides to the Red Gyptal Paint?
Yes. A Yes is not good, additional detail needed.
I reviewed many internet discussion logs concerning Red Gyptal paint use inside of crankcase's.
There are users and non users of Red Gyptal paint in these discussions. Non users out number users by a wide margin
The down side mentioned most often is the possibility of the Red Gyptal paint breaking free and contaminating the oil, clogging the oil pick up.
That the Red Gyptal paint can break free is mentioned only by the non users. I have found no occurrence where an actual user of Red Gyptal paint reported that the coating caused any downside issues. All upside benefits mentioned by all the users are conjecture as I have done in the initial three bullet points.

and that is my story and I am sticking to it :roll:

Years ago Hotrod magazine suggested Rustoleum white enamel. I tried, it worked, but I doubt if it made any difference.

My take? I seriously doubt glyptal will plug up the pickup. I would also bet the difference is too small to measure. What would intrigue me would be if it speeds oil drainback maybe you could reduce windage by running less oil in the pan without running it out.

Bottom line is if it makes you happy to do it, do it. :D

The good weekend that I had a Wilksboro changed the short term plans that I had for the 68 Barracuda.
I thought that I would be dissatisfied with the performance of the car. And to correct that, finish assembly of the
new-improved slant motor, get it in the car an head to Knoxville as a test run ahead of Clay City.

A little success changed all of that, I am not changing anything on the car. Its going to Clay City, as it was at Wilksboro.

After Clay City, over the winter months I do plan to make some revisions to the car.
I always wanted the 68 Barracuda to be a street car. And I really like Lou's approach to drag racing. Drive the car there.
Driving the car would simplify the process of getting the 68 Barracuda to the strip, I am thinking that I would make more races.
The car has been to two Slant Six racing events.
Sept 2017 Clay City, six test runs and four races.
July 2018 Wilksboro, eight test runs and ten races.
I want to increase the number of times I get the car out, to 'play'.

The plans are:
Slant Six, will plan to use the new-improved motor that is in process of being built
Stay with the 904, to streamline the process, will be a a833 car eventually
Add AC, comfort for the highway trips
Mininal interior, no back seat
Add crash protection, roll bar, improved seats and seat belts
Leave the exterior paint, trim, glass as is
Renew and strengthen the under body

The goal for 2019 is to have the 68 Barracuda running as a street car that I can drive to a Drag Srip or Autocross event,
and have fun with :D on a frequent basis.

Street It!

Im enjoying my DeSoto built for touring everyday.

My mud drag car was fun for 5 seconds 20 times a year......not so fun for the 80 hours per year of towing.

i think Seymour is the tour/race innovator...and Lou is the tour/race role model.

Working the plan to make the 68B a strip - street car.
Plan is to do an under side and engine compartment restoration, the car is getting new floor pans from the fire wall back and new inner fenders.
I have a shop in Anderson IN hired to do the metal-weld work, waiting for room to open up in their shop.


Putting the motor together, it is a last year 1987 cast crank slant.
some of the components are:
KB 239 one mm oversized pistons
K1 cast crank rods
King AM rod and main bearings
I-J up and down crank scraper
Mopar Performance windage tray
ARP studs in mains 1 & 4
Milodon BB Chevy tray studs in mains 2 & 3, those tray mount studs are not a low cost item, but they allow for adjustment to get the tray and crank clearance right.

The cylinder head is at a shop owned by one of the engineers that I worked with back in days when we worked for that Chicago base truck manufacturer.
He was an engine air flow specialists then, and he has moved on to that big bore engine manufacturer located just south of Indy. He has a really nice Serdi Valve Seat
Machine, we will see how it all turns out.

The morning of Christmas Eve day, and the 68 Barracuda went into the restoration shop for floor pans and frame work.
That is a nice Christmas present for me. :D

The shop is American Classic Restoration in Anderson IN

I interviewed and did a walk through of a couple of local restoration shops. I went with ACR as their shop is clean, organized,
they were willing to work with me on the timing and I had previously seen some of their work, good stuff.
Another plus was they do a lot of mopars, they currently have full restorations going on: a 57 Chrysler 300, a 68 Roadrunner and a tribute '70 Superbird.
Vlaid commented to me that the guy having the 57 Chrysler redone is going have over 8 grand just in chrome work.

Getting the 68 Barracuda in the shop today is about a week off what was planned by ACR back in late October, but that is still well within my planning time frame
of getting the car back to my garage in early Ferburary of 2019 so I can start my task of putting it back together and have it on the road by May.

I am currently working on rebuilding the steering column, after that I will put the cam in and build the cylinder head and finish up the motor.
