Is my engine performing as it should??

once you get the cam changed or spring changed...

you will be fighting the stock converter and 3.23 gears....

duster in sig has same problem stock converter and gears...and small tires..

in las vegas, trap speed was 101.26 but with eddy heads...and it is not a 340 but a 360.
cam is a hughes 230/237 with .515/.535....eddy air gap, holley 750.
