340 vs 360... virtually every SBC I see on my regular Saturday night haunt has a larger bore than our 360's can manage. There is a reason for large bores....
Do you realize that .040 is, the difference between a 360 and 340, almost nothing in a 4.000 bore. I am not interested in SBC engines, I rebuilt too many of them. How many Chevy parts are in those motors? My friend ran a 350 and I always teased him that he spent $10,000 to make his SBC into a stock SBM. Bore size is not where the power is, it is airflow through the heads. Why do Super Stock Class cars run almost the same times whether a 273, 340, or 360 using the same heads?
