I pulled apart the 750 DP to take a look inside and what I found was thst the front jets are 70's and the PV looks to be a #5 (there is also what appears to be 4 across from the 5(?))The rear are 82's. Also, the rear PV is blocked. Does this sound about right for my 454 ho?
Thanks again fellas.

I'm running 72s in the front with a 4.5 p/v and 82s in the rear. Mine runs great. I just put it on and might be a little lean in front but it runs perfect. The only difference is that mine is vacuum secondaries. my car was always to rich on idle with my 850 dp so I finally switched.

I run 74's in my 3310..rear is stock metering plate
