cool - ty TIM!

 

I have my heart set on a 383 but was worried that I would need to settle for a 350 to pass emissions. I'll drop in the stroker and stop back by if my levels are off.

the cam timing, compression ratio,cattalitic converters, state of tune, the condition of your rings and valve seals, and ignition timing , valve adjustments, will have a great deal more to do with your passing emmission testing than the increase in displacement a 1/4" extra stroke gives the engine

ive used a crane 114142 cam in several nice 10:1 cpr 383 street combos and they all passed emmission testing with flying colors

yeah, you can go with a wilder cam, but this cam in a 10:1 cpr 383 makes for a great street torque combo and easily passes emmission testing

 

btw given the correct heads ETC, a combo like that gets you about 400 PLUS fly hp/450 PLUS fly tq which makes even a heavy corvette a low 13 /high 12 second car and add a 125 hp nitrous system and its a whole new ball game
