i agree with what Bill said here..it will grealty determine what type of application its going on also.
the winston Cup guys are a running a 750hp engine at 9,000 rpm for 500 plus miles using a high performance mechanical ( stock location) fuel pump..with a #6 line.....Carter is a brand they use a-lot.
if i were going to be driving it on the street as a TRUE street/strip car,,the Holley Volume MAX fuel pump is an excellent choice..some of these mecahincal pumps must be regulated also. if this is the case they sell a nice carb mounted regualtor kit that works nice and neatly.
if you are dragging only..electric pump mounted as close to the fuel tank as possible..because of what Bill mentioned as far as pushing the fuel
i run a magna-fuel on my 511 bbc...very nice pump and probaly a little over kill..many pro-stock boys run this pump...
My opinion for the best all around electric fuel pump on the market that takes care of most 700hp motors/engines on down IS "OLD FAITHFUL"...HOLLEY BLUE...you cannot beat these pumps with a stick...mount them sideways , upsidedown, under the tank, on top of the tank...the will work...
just my opinion here.....i will advise to stay CLEAR of the Barry Grant pump : King endura" and anyother BG products for that matter its a BIG PIECE OF CRAP in my opinion..Plus i feel BARRY Grant is one BIGGEST rip off artist of this century...if you do not believe what i say..i ask anyone that has ever had a BG 400 pump and got one o-ring gasket leaking and had to send it off to BG....THEY GOT CHARGED $250.00 to replace a $2.00 o-ring that they would net sell you..BECAUSE THEY ARE PIRATES in my opinion...
Someone out here got wise and killed BG,,cause now you can buy these gaskets kits less than $15.00.....BG could have kepted this main line business and charged $50.00 abd still made boo coo's of money...but NOOOOOOOO..that wanted the grandslam....
PISS ON BARRY GRANT AND HIS GREED !!...( my personal opinion)
also in my opinion thay haven't had a decent carb since the silver/gold claw verison....
