You can delete it,it will run fine. My 97 chevy truck used to have a 400 small block with 11-1 compression 490 lift Summit cam,long tube headers ,no cats,and vortec heads and intake,and stock computer,though I did adjust fuel pressure to about 70 psi and ran only 93 or 94 octane gas. I also had a MSD 6a box and blaster coil and solid core wires. It ran good,but I always thought the stock intake manifold was retarded,and would probably have a lot more power with a good intake and carb,and a real dist instead of the stupid plastic one, which was always getting wet.
