I'm "freshening" my 78 4 bolt for my K5. I'll be running a 465 with 5.13s and probably 39.5s. Engine will be mild with around 9:1 compression. Thinking of going with the Edelbrock Performer intake and matched cam kit for good driveability. Anyone running this package or have another idea for a cam? Also looking at running a matched Q-jet from Jet perhaps or Holley's Truck Avenger. Any thoughts or experiences? I wanna do it right the first time. /forums/images/graemlins/hack.gif
