Hey guys hope someone out there can help me. I am running factory stock class and i am finishing up my new motor. I was wondering if all chevy mechanical fuel pumps for 350's are the same or is there certain years of certain cars that flow better(without return line). Thanks for any help you can give me. Chris

I like the Carter mechanical pump. It will handle plenty of flow, but it's not as big a body as the Holley high flow pumps. It's an all aluminum housing that seperates in the middle with screws so that you can rotate the inlet to suit your chassis. You can get rebuild kits for them. It uses 1/4" pipe thread inlet & outlet instead of the clamp on inlet that most cheapies have. It has a stronger arm that contacts the cam and It was original equipment on some hi-po Chevies in the 60's. AC makes an equivelent pump, but more expensive. The Carter will run you about 60 bucks.

Oh yeah i have to run a stock appearing pump so the aftermarket ones wont work. That is why I am trying to find the best flowing factory pump.

Small block carbureted Corvettes from the late 60's. Has to be pre-emissions or the pump has extra fittings for return lines. AC makes one and I believe that Carter was an OEM supplier for GM fuel pumps in the sixties as well (carburetors I'm sure of, Carter AFB on GTO's).

I just looked at advance auto parts online and they have a carter mechanical with no return for $25 bucks. I think that is what i will go with. Thanks for the help guys. This is an awesome forum. I am just getting started in the racing scene and i have found so much info on this site. Now if I could just find someone with some parts front suspension and brake stuff for my 71 skylark. Thanks again guys.

Check with THERON#40 he's running a 64 Chevelle, maybe he's got some extra disk brake front end stuff.

That's not legal and way too much carb for your motor Chris

I notice some fuel pumps are alot bigger in height than others. I think the corvette one is a tall one, does this provide alot better performance than a short pump?
