Edelbrock Pro Flo 4 EFI
what is you engine setup and map used?
'90 LA 360 roller block, Eddy LA RPM heads with the pushrod tunnels clearanced and gasket matched intake ports, 10.25:1 compression, Hughes 226/230 cam, headers. 4.10 gears, 727 trans with a currently stock converter, however the trans is coming out shortly for a freshening. Been in there 13 years. Considering a 2200 stall, but I pull a 4500lb camper with this truck so can't get too crazy on the converter. Turns about 2500 at 60mph.
The too large for low down grunt intake ports are even bigger now. Had to take out up to 3/16" on the port widths of the intake. The mismatch was horrible, and none of the port windows were the same size. The CNC'd port openings in the heads looked like hell too, had to do several hours worth of cleanup on those as well. Lousy quality work by Edelbrock in my opinion.
Using map 5014 in the computer, per a 45 minute phone call with Edelbrock tech. This thing just doesn't have the balls it should have. Stock converter aside, nailing the throttle from 3000 to 5000 rpm is mediocre at best. WOT fuel is currently 12.8.
