Spoiler is probably not helping much. With those gears, I would expect that low compression 400, 700R4 and 2.73 gears to be pretty miserable below 75mph, even with a Firebird being relatively light. 1800 RPM does seem on the low end too, but I expect an engine like that to be making 90% torque by about 1500.

Just to humor myself I decided to measure the volume of the chamber on the '66 1bbl head I modified to see what it is and to plug that number into my engine parameters. It came out to 65cc's and have 9.55:1 compression on my engine, which is about 1.25 more than it currently has. I'd have to work over the other chambers, do some porting, and possibly minor machine work for me to be happy enough with it to use. I do think I have some brand new OE valves for this head, and I probably would shim up the springs it came with. If I used a set of TRW LF2289 pistons and cut some small valve relief's in them, my compression would be a flat 9.0. So I think I may have a game plan for a "back up" engine. What I'm considering for my primary turbo engine is getting some forged flat top pistons and have some minor valve relief's cut into the top and that should net me 8.8:1 or so, which is good.
Escaped on a technicality.

The wife and I are heading out for the Car Craft Anti-Tour later today. Going to take a leisurely drive to the mountains, then out to the coast before the start then up to Morro Bay for the car show there (part of the Anti-Tour). It'll be a a bit over 1,500 miles when all said and done. Hoping for a trouble free drive and a fun few days I wanted to visit the sailing rocks in Death Valley on the return, but it appears to be a ton of dirt road and actually more worrisome is running out of gas! Will have to check that off the bucket list another time.

haha, Yes, government rules dictated we get married within 90 days, so we had a short wedding in Vegas with my parents. Larger more extravagant wedding plans are for October or later (after Drag Week
Viva Las Vegas!
Through the magic of black duct tape I temporarily installed the Raspberry Pi and screen. I have it hooked up to a battery power source so it doesn't reset each time I turn the car off, just have to remember to shut it down at the end of the day.
