Initial jetting recommendations wanted - 09/06/16 01:42 AM
I may actually be firing up my 451 soon and would like to know what primary and secondary jet sizes (and power valve) I should start with.
10.3 CR, ported iron heads, .654" Mini-Express cam (316 advertised, don't know the .050 but prob around 270), 850 DP on Edelbrock RPM, 18 initial/34 max advance, adjustable vac advance can, 1-3/4" headers, dual 3" exhaust with x-pipe. Probably idles at 1000-1100 rpm with 7" vacuum.
I have an O2 sensor bung and will be putting in a wideband sensor/gauge for dialing it in, just want to fire up something approximate for easy break-in and shakedown cruise.
Thanks for any recommendations.
