I have the Roush 427 SRTW #460. I got the Cobra used and it came with a Bigs Performance Products 750 Stage 5 Carb. The primary jets are 75, secondary: 82, primary power valve is 4.5, there is no secondary power valve, the primary & secondary shooters are both 0.035, the idle feeds are 0.033, the idle bleed is 0.073 and the main bleed is 0.036. I wonder what all that means! I get about 13 MPG. The engine seems to run perfectly. I don't think it has ever stumbled. The original owner did not like the carb that came with the Roush. Made me wonder how could that be??
