 The stock sizes in that carburetor were .072 Jets, Primary Rods 50M, Secondary Hanger K, Secondary Rods DP. We will see what others recommend for that carb.

I really want to know what size jets and metering rods I should put in that carb so that it will run my 305. its not an h.o. motor. its in a 1983 pontiac grand prix that I took the computer off. I put an RV camshaft in it and a edelbrock performer intake. everything else is stock.

the primary rods look like they are 48's or 49's. I also have a set of 55's that I can use I just dont know what size jets to use with these rods. my jets are all scrached up so I could not tell you what they are for sure.

the secondary rods are dp's and the hanger is is a h

 Yeah, I was just giving the stock specs, in case Cliff or someone needs to know, instead of having to look them up. ;)

I'd install the stock metering rods if they are in good shape.  Those carbs used "M" series rods.  At most go up one jet number for initial testing.  This new fuel has less BTU's than older formula's due to the ethanol content and reformulation, so it helps to add more of it for best results.....Cliff
