360 coming back together

Always remember that once the peak is reached, a few cfm gain is not worth using a .600 over a .550 or over the .500 or whatever lift cam is in your head right now. The extra push on the valve springs is just asking for more maintenance and the small cfm gain isnt going to be a noticeable increase in power. 1 cfm = 2 horsepower, think about it, flow charts reflect that, 250 cfm generally pulls 500 or so horsepower, once your hitting the 280-290 (the ceiling on a decent pair of aftermarket heads) you should be around 550-580 horsepower.. Also, porting too much raises the powerband which destroys any low rpm breathing, and thus, any chance at driving smoothly on the street is destroyed. Not only that, its just harder on valvetrain. Dont forget about torque either, low end is important.. port velocity = torque, big ports arent always the best way to go.

Good luck, hope the build goes well :salute:
