Seems like a pretty stout build.
Getting the air in has ways been the more difficult part of running the slant. The small bore doesn't allow for big valves without shrouding them really bad.. which of course has effect on the flow characteristics from one side of the port to the next. I hear 200-220 cfm is about it. Most I've gotten was 202cfm on one port and the rest 196-199cfm w/1.7 intakes.

port flow numbers. I have 30 degree seats on this head. This gives up some flow at the higher lifts, but comes off the seat faster to get the flow started sooner.

68 B 061022 - YouTube

a list of the bigger projects completed on the 68 B over the Winter 2021 and Spring 2022 months

* Installed Roller Rockers, B3 valve train optimization shims, new pushrods, installed
valve spring retainer bushings, modified the valve cover to accept the higher positioned valve train
* Installed Tuff Wheel and adapter
* Re built 8.75 differential with new 3:55 ring and pinion
* Installled a Wagner adjustable PCV and Moroso vapor catch can
* Built brackets and trim necessary to mount quad headlights and custom grill work.

I am quickly running out of reasons to not drive this car.
I had rolled the odometer back to zero, when I started this project. The odometer is currently setting on 260 miles.
It is a 'Go' from there.

I will post a few more photos of the projects listed.
 
The B3 rocker shaft shims significantly reduced the travel of the rocker rollers across the valve stem tip.
But they also moved the rocker shaft up over .200 and to make that work I needed new pushrods and a modified valve cover.
I added up lifts on the ends of the valve cover for clearance and moved the vapor containing baffles to the outside of the valve cover. To make a nicer routing of the PCV piping I swapped PCV and air intake positions.

The goal of the new grill was to add an engine air intake, reminiscent of what was hot Rod stuff in the 60's and at the same time make it look like something Mopar could have done in 1968 and at the same time not do any changes that would impact re installing the original OE head lights and bezels.
This was an interesting project, and its done.

The OE steering wheel on this 68 Barracuda is just absolutely perfect. Has a nice shine, no cracks.
I am wanting to drive the car aggressively and I felt that a thicker steering wheel rim would give better turning grip and at the same time I would not be stressing the nice OE steering wheel. I like the way the Tuff Wheel looks and feels.

Been doing some local driving to run up a few break in miles and to establish the reliability of the car.
The photo below is of the car using it as a Grocery Getter. That day in the parking lot independently had two sets of folks approach me saying
"that car is just beautiful, what is it?"

I now have 330 miles on the car. The last trip was a 20 mile out and back, all highway. The fuel milage was 17.9 mpg on that stint.

Pulled the sparkplugs to do a compression test
the cranking pressure for 1 to 6 are
195, 190, 183, 190, 183, 185

I also adjusted the valves

I have the AF and VE tables adjusted good enough that the car starts and drives easily. No bogs or hesitations.
I think I can tune it a bit better for more performance and economy.
