I am also a bit concerned about oiling! Though This 455 has warrior billet 4 bolt main caps & a SD 80 psi oil pump & 74 SD rods ( I know, too high psi, this is the way I bought the car ).

There likely is no reason to have a 4:10 gear in this car & turn 6200 rpm+, as I will always run a stock 26" street tire. No porting on the stock 72' d-port heads & #041 cam, I wonder what rpm I should shoot for through the traps? & what gear, maybe a 3:73 or even a 3:55? For this year I will be racing with the 4:10.

Any reccomendation for a good quality mech. fuel pump? Need no more than6psi for my Q-jet.

Thanks again guys!!

It's a proven fact of the 041/455 combo's, shifting above 5400-5600 max does nothing for performance. All you would do is over rev the peak power of the engine possibly causing damage. Do some searches on the setup there are many examples. Way back when Jim Hand had this setup in his wagon he shifted at 5200 rpm for best track performance. Good luck! JD

P.S. Crower springs all the way!
