Re: 408 for 550FWHP, Can it be done?
Definately ditch the Edelbrock carburetor. There can be 50 horsepower lost in the wrong carb. My little 306 makes 1.63 horsepower per cube, and you are only asking for 1.34 with an unlimited selection of parts. The only thing someone hasnt mentioned is those goofy flow numbers you posted. Your heads flow 225 on the exhaust, but only 275 on the intake?
