If thst is the hi-flow base and LT runners you could expect to see around 15chp gain.

Default big mouth and slp runners

hi

I just installed the edelbrock hi flo and slp runners, took about 5 hours, but because the slp runers have a thicker flange and are generally larger, it was quite awkward with the fuel rails, and only use the standard intake bolts between the intake and the heads as ARP ones foul the runners slightly.
