Slant Six Forum :: My Arm is Sore... Inside Look at a SL6 Head

This view of "inside the SL6 head" helps me visualize how the upper and lower water jacket cores were done (by the factory) and how they could be layed-out in an after-market head.

So are you saying that your working to develop an aftermarket head?

I have had the plans / blueprints for an aftermarket SL6 cylinder head for over 15 years now.
I have "run the numbers" twice... got quotes for castings, machining, (including programming, holding fixtures, cutters & taps) and the final "press work". (installation for 12 guides and 12 valve seats)

When all is said and done, we always find the same answer, "too expensive".

So... I always know what "next steps" are needed for the project and time can be your friend.
This year, I was able to move a few steps forward... finding someone with a big saw was one of those forward steps.
There are still many more to go.

Our local high school (165 students) offers an Art Metal 12 class that involves casting aluminum. They use a propane setup. My daughter (she is now a ticketed welder) loved the process and was allowed to pour whenver she had a mould. Most students make a shifter nob , ashh tray , death metal shrine, pipe stand or a mess. Kate got into fantasy figurines, four pound dragons etc. Tim:you should drop by sometime so Kate can take you up to the school.... Anyone interested in casting art should out Fredrick Remington. I was thinking it would be fun to port Dougs 2 piece head .....deck the two pieces for reassembly ......glue and clamp. I bet porting is more fun in a 2 piece head. Then you try it in plywood. Glue and clamp... Keep posting pictures Doug.

You can do a prototype head from steel weldments. Years ago Crosley brazed the block for its tiny Hot Shot motors. http://crosleyautoclub.com/Mighty_Tin.html There were warranty and corrosion problems, they went to an iron casting, but the thing did work. With the improved welding of today a welded prototype can work for a one off. With CNC you could fabricate and weld up a few test heads.

Unless you have a better Idea, I think it might be: "Bill Weertman, the Chrysler chief engineer who worked with the Slant 6 development program from 1958 to 1987 ."( c & p from the Articles section.) Anyone got any better idea/theory ? cheers,CRM

I thought about "BW" meaning "Bill Weertman", but I'm pretty sure he signed most of his work "Willem", not "Bill".
