Attached is the .bin file I ended up with on my 93 K1500, with the following engine modifications.
Bone stock Swirl Port heads with performance valve springs (Z28 springs) and 1.6 roller tip rocker arms.
Bone stock L31 Vortec roller cam and lifters.
9:1 Compression Ratio
Modified Stock TBI intake, throttle bores enlarged to 54mm. Also radiused the throttle bores.
454 Throttle Body with Cop Car Injectors (65lb)
Shorty headers, with 3" single cat back exhaust system.
0 - 60mph in slightly over 7 Seconds!
The performance fell flat at 4500 RPM's.
