I'm almost positive that I've asked about this before but I would like more detailed answers on why.

Which would be better to run for a daily driven fun car? Turbo 250 or high compression N/A 250? Would you be able to make anywhere in the 350-400hp range with a high compression 250 without running race fuel all the time? What are the mpg differences? Which is more reliable?


69 Buick Special Deluxe. Intercooled Turbo Chevy 250 @ 15psi on a stock long block. It's kinda fast.
