Hi, my son sent me that link this morning.
I don't know how to post them but I'm glad you did.
Interestingly enough, Brad Wallace is mentioned. I knew Brad Wallace, he was our car owners engine builder.
His engine shop was called Horsepower Hospital in Maryland.He was definitely a mechanical genius, and I wouldn't be surprised if he built that engine for a customer.
I was much better friends with Brad's brother Dewayne, and nephew Bobby Wallace. We were all involved with Saturday night stock cars at Riverhead raceway. We are all from Long Island, NY.
Back then our motor was the Chevy 250.
Brad put in 14:1 compression, big block Chevy roller rockers, big block chevy fluid damper etc.
Now my son Peter runs into Bobby every now and then, and will certainly show him the clip.
It is pretty mind blowing to see the details of this engine.
Unfortunately Brad Wallace passed away a while ago.
Good luck
B RON CO. Still workin' on it!

I'm not a facebook member. Can someone contact this guy to see if the owners would be willing to let a casting be mode of the heads? This would be a nice addition to the work that WorldChampGramps and others are doing for a set of aluminum heads.

Bruce AKA "WorldChampGramps" was the one that developed the six piece head using 351C heads.
Using that head on the 300 six in a Pinto he was able to win the 1975 NHRA Championship along with other National titles. See the following links for details

https://www.ford-trucks.com/forums/show ... stcount=50

We expect the new aluminum crossflow head to outperform the old six piece iron head.
The old head used two short pushrods with an intermediate lifter in between.
The new head will use a single pushrod and all the rocker arm assemblies are available as "Off the shelf" items.

In addition, a mold could not be made from the head and used to cast a one-piece aluminum part because the mold has to be "scaled up" to account for the rate of thermal expansion of the aluminum. Otherwise when it cooled it would be too small.

I was going to post the second video, but saw it in here. I was thinking of changing the name to "6 piece Cleveland headed 300 six", or similar that should get more interest, views, talk, etc.

Something I noticed that interested me is how easily it looks to run link-bar roller lifters. Most have said it would take removal of the lifter cover stud bosses. It doesn't look that way. Base circle and lifter height would need to be calculated, but it only looks like minor clearancing to the bosses and/or link-bars would be needed and a stock cover would work. It gives me hope of one day getting a hydraulic roller at an affordable price, even though that one is quite old and probably out of my price range.

It also looks just like a Crane cam core to me from the tell tale bronze coloring.

Anyone have any info or ideas on the crank? One off or modified stocker? Just curious though, not really interested in using one.

Also interested in opinions on why the gasket pushed into the cyls.

My experience is that only the square end bosses prevent installation of tie-bar lifters. On the engine shown they chose to grind away the tie bar on the end cylinders. I do not like that - instead I grind away the lower part of the boss on the block.

I think the crank is a Moldex Tool piece.

The head gasket looks too thin to be reliable to me. Maybe that's why it deformed. I wonder if he was using 1/2" head studs or the stock 7/16"?

I'm still betting he will find pieces of the head that need welding and further machining.
