      Whats a good choice for a mechanical fuel pump for my 383? I was thinking about getting this one

      http://holley.com/12-327-11.asp

      Is 110gph sufficient for my horsepower?

      A mechanical pump "CAN" drop fuel pressure like that

      You need a video like that at the track for a solid 1-2-3 run

      The reason the fuel pressure drops is the pump has a cut off pressure, at a certain pressure it cuts off then builds up pressure again

      For example read this Holley pump here

      The Carter pump is 7 to 8.4psi cut out pressure

      I am considering going back to a mecahnical fuel pump (mainly because I am not good at fabrication, so my current electric fuel pump mounting location is not ideal). I have the correct fuel pump pushrod on the way from Straub Technologies (who I purchased my cam from). My question is would the Edelbrock 1721 or the Holley 12-327-11 fuel pump be better?? 383 small block, that is supposed to be around 500/500.

      Now, if there is someone close to me who is good at fabrication and would be willing to help me get the eletric fuel pump moved to a better location, that would be awesome (I would not expect them to work for free). I do like having an electric pump, simply because I can prime the carburetor quickly if the car sits for a while, but this is the second time that the motor has quit working on the pump (it was rebuilt in 2013 - the original one only lasted about 4 years).

      Let me know what your thoughts are. Thanks in advance.



      P.S. If someone knows of a straight through electric fuel pump (i.e. cylinder shaped) that would work well in a carbureted application, I am open to suggestions there. All of them that I have seen put out a lot of pressure, which requires a regulator (and I don't know if the regular Holley regulators will work at 40 PSI and above).
