Edelbrock heads

Alright, I thought I would vist the 5.0 forums to ask this question. My buddy has a 1993 5.0 5-spd with the following mods done: 3.55 gears, long tubes, off road h-pipe, and flows along with a chip.

My 97 4.6 has 4.10's, SCT custom chip, PI intake manifold, X-pipe, and magnapacks. On the highway our cars are dead even but from a stop I get him pretty good.

Anyways, my quetion is he just got some Edlbrock heads, their intake manifold and cams made by Edelbrock although not too agressive. How much power is going to be making and how bad is he gunna whoop me now? Thanks guys.


future mods for me are- throttle body, intake plenum, and torque converter:)
