i just put the edelbrock perf. rpm package on my 289. i need to rejet my carb for this change(stock heads, performer cam). anybody have a ruff idea of what metering rods/jets they are using so i can get in the ball park? thanks
Amazingly, I went from a stick 351 windsor to a 393 with the RPM package, and I haven't rejetted my 750 Holley. Until I can get on a dyno or get a wide band, I am not going to guess at it. My plugs read fine.
I recommend you change to a holley also. I had an edelbrock 1406 on my package and then changed to a holley 600 and it was like night and day. I also could never get the edelbrock to run smooth even after rebuilds. I just need to do some more fine tuning on my holley and It will be one of the best changes I have made.
