Define "best".What is the best after market intake for a 93 5.7 TBI engine in a truck?
I'm running a "ZZ4" intake, adapter for TBI, purchased adapter for EGR, and (home-made) adapter for EGR. Downside is that the two center bolt holes to the heads on each side would be at the wrong angle for TBI heads; and there's no bolt hole boss for the A/C strut, or for the bracket that holds the MAP sensor and ESC module. The EGR adapter fabrication was the worst part.I’d be looking at a dual plane setup for a carb with an adapter plate
possibly a dumb statement here, but i would not recommend a dual plane intake for any TBI style injection...cylinder distribution is horrible.
i had an edelbrock TBI intake (dont even recall if it was single ir dual plane)...but during the motor swap, to vortec heads i ordered the edelbrock perf. RPM airgap, and currently runninga fitech easy street 600...the idle characteristics and AFR are all very finicky. i have had several conversations regarding this, and a SINGLE PLANE has been recommended by all with out question as the first thing to swap.
i just recently trimmed out the divider and added a 1" spacer...already it is much smoother idle, and the AFR's are much closer to commands
