The first head to document will be an old E88 from my 72. I used this head a long time ago worth 40DCOE triple Webbers. In typical fashion long long ago I did my best to do what I thought was right. I blended the seats to match the bowls with a grinder, and port matched the head to the intake, opening up the port about 1" in from the entrance to blend the new opening (not good). other than that, stock valves and chambers So lets flow it. Hoping to borrow a stock E88 to compare later. Some pics for referance Here are the head Specs Cylinder 2 Intake with 84mm Bore And Cylinder #2 Exhaust with 84mm Bore I then switched out the bore to 86.5mm and tested again, here is a comparison chart of the effect of only a larger bore Sorry the image is hard to read I need to figure out how to upload better resolution pics, but you can download the PowerPoint below E88_Flow_Bench_Comparison_Cyl2_84mm_vs_86.5mm_FIXED (1).pptx

09-06-2026 ATLAS Z UPDATE: Ok, so I mounted my electric panel into the car and began wiring it up. The garage is SO HOT. I had to go inside and get a fan to blow in there on me (see pic). going pretty well! about 75% done. PICS

Last weekend i got the offer to run a single day of a multi day event if I wanted to shake down the car. So i scrambled all week getting a bunch of things checked off the list. a couple days getting up at 5am and working for a couple hours before work and then to 10-11pm after work but got it so i could run it. Added a front splitter. strut bar, seat belts. fuel cell bulkhead, fire extinguisher, coolant overflow, battery tie down and kill switch, tow hook, brake bias controller, some tuning changes and im sure a few more things. But i made it. My uncle and I loaded up friday evening and saturday morning drove an hour and a half to the track. Had a great time. car was an absolute trooper and didnt skip a beat. New track for me so had some getting used to the track and the car. but i did 4 sessions problem free, I didn't change a single thing all day. found one loose bolt after session 3 that i caught before it was a problem. Car performed well. Had a fairly competitive pace by the end. Anyway. huge photo dump
