I have 96 chevy C1500 with 5.7 with 237,000 w/ poppets still, I've had same upgrades on it since about 98-99 ish. Air intake, throttle body spacer, did cap and rotor, MSD wires, Flowmaster, and hypertech computer.
Been tinkering with Throttle body and spacer, Bored them both out to 78 mm. Than ported and polished throttle body to hourglass figure to where only blade is sealed when closed. Throttle response is much improved, also completely remove baffle and welded up holes and knife edged 2 edges. Added (also remve half of blade shaft and added 2 button head SS screws to hold blade.)
Also de screened mass air flow sensor with no ill effects.
Asked for performance dist. Dyna mod ignition mod and Screaming demon coil for Christmas.
Want to remove acordian intake tube and replace with alum and a rubber intake elbow. Worndering if throttle body lip is enough to use hose clamp?
Others to do in future
Underdrive pulley and overdrive for alt
Efans LS
Ac Delco 217-3029 inj
Taylor Vmax spacer while i do inj.
Patriot full length headers
Added (New high flow cats, still have orig.)
LT4 Hot cam
Gear drive while do cam
411 computer swap
Re tune
I know list is long, but start with bolt ons and progress little by little.
Thoughts?
