here are some basic numbers everyone should know before modifying something:
oversquare engine- bore bigger than stroke, good for high rpm and hp
undersquare engine- stroke bigger than bore- good for high torque
potential hp- .2575 x head cfm(at valve lift) x # of cylinders (hp based on air flow)
max cam lift- .25 x intake valve diameter
rod ratio angle- length of rod / stroke (optimum gains 1.6-1.9)
piston speed- stroke x rpm
(cast iron 3500 fps factory forged 4000 fps billet titanium 5000-6000 fps numbers increase greatly if cryo treated from onecryo.com)
everyone is welcome

thanks for the info, I'll remember that next time I change my mufflers.

this section of the forum is based on performance, and performance is a lot more than a freakin muffler, personally, i would rather smoke something than sound good and as for my other post, yeah, was a little drunk last night, somehow got maf confused with vane, my apologies and thanks for putting me in my place
