This is a just a "what if" theoretical post, but I am giving it more and more thought. I really want to build a NA BBC to run down a lot of the boosted kids. These days, that's a serious machine, as 1000+whp is no big deal from a 5.3 with a ching-chong turbo. Basic parameters would be std deck, Dart alum block, heads(?) and definitely fuel injected and pump gas/E85. This would be in a 'street car', small tire/DR, mostly roll races, but I like going heads up- so maybe a chassis car. How far can I go? 1000whp, 1200whp? I realize at roughly 600ci, I would be 2+hp per cube, so that's probably not possible on pump. I do think I can get the weight down, obviously, this turns into a hp per lbs calculation= x speed. For sake of argument, figure a 2700-2800lbs vehicle, just for calculations. Just some thoughts, let me know what you think. My gut feeling is big bore- short stroke, 8000rpm in the build. I am just curious how far I can go or how far anyone else has gone. FYI, I already know everybody w/ boost will be laughing and crying "no way", but I like to beat up people bigger than me. So far, I have had good luck.
