Understand the need for a clutch, I'm still there myself and always will be. Passed my driver test in a 2 year old '66 Malibu with 3 on the tree. Converted my '67 ss/rs Camaro from pg to 4 speed during the "Day 2, 3, 4" restoration...
Now has full tubular front arms and disc brakes.
Also, understand the desire for real ss cars. I don't build clones/tribute cars. Needing a real '70 SS that started life with solid lifters puts you in a very small atmosphere right from the start. If you can tolerate "upgrading" an L34 or LS5 to a solid lifter engine, it will be easier.
